Anglophone

Anglicisation or anglicization (see -ise vs -ize) is the process of converting verbal or written elements of any other language into a form that is more comprehensible to an English speaker. Or, more generally, to alter something such that it becomes English in form or character.
The term most often refers to the process of altering the pronunciation or spelling of a foreign word when it is borrowed into English. Personal names may also be anglicised. This was rather common for names of antiquity or of foreign heads of state, and it was and is also common among immigrants to English-speaking countries (e.g., Battenberg became Mountbatten).

Loanwords

Non-English words may be anglicised by changing their form and pronunciation to something more familiar to English speakers. For example, the Latin word obscenus /obskeːnus/ has been imported into English in the modified form obscene /əbˈsiːn/. Changing endings in this manner is especially common, and can be frequently seen when foreign words are imported into any language. For example, the English word damsel is an anglicisation of the Old French damoisele (modern demoiselle), meaning "young lady". Another form of anglicising is the inclusion of a foreign article as part of a noun (such as alkali from the Arabic al-qili).

Proper names

Place names
Place names are commonly anglicised in English. Examples include the Italian cities of Napoli and Milano, known in English as Naples and Milan, the German city of München (Munich), the Danish city of København (Copenhagen), the Swedish city of Göteborg (Gothenburg), the Dutch city of Den Haag (The Hague), the Spanish city of Sevilla (Seville), a number of Arabic speaking places, like Cairo (القاهرة Al-Qāhira). Such anglicisation was once universal: nearly all cities and people discussed in English literature up to the mid-20th century had their names anglicised. In the late 20th century, however, use of non-English names in English began to become more common. When dealing with languages that use the same Latin alphabet as English, names are now more usually written in English as they exist in their local language, sometimes even with diacritical marks that do not normally exist in English. With languages that use non-Latin alphabets, such as the Arabic, Cyrillic, Greek, Korean Hangul and other alphabets a direct transliteration is typically used, which is then often pronounced according to English rules. Non-Latin based languages may use standard romanisation systems, such as Japanese Rōmaji or Chinese (Mandarin) Pīnyīn. The Japanese and Chinese names are spelled English following these spellings with some common exceptions, usually without Chinese tone marks and Japanese macrons for long vowels (Chóngqìng to Chongqing (重慶/重庆), Shíjiāzhuāng to Shijiazhuang (石家莊/石家庄), both in China, Kyōto to Kyoto (京都) in Japan).
De-anglicisation has become a matter of national pride in some places and especially in regions that were once under colonial rule, where vestiges of colonial domination are a sensitive subject. Following centuries of English rule in Ireland, an argument for de-anglicisation was delivered before the Irish National Literary Society in Dublin, 25 November 1892; "When we speak of 'The Necessity for De-Anglicising the Irish Nation', we mean it, not as a protest against imitating what is best in the English people, for that would be absurd, but rather to show the folly of neglecting what is Irish, and hastening to adopt, pell-mell, and indiscriminately, everything that is English, simply because it is English." Despite its status as an official language, the Irish language has been reduced to a minority language in Ireland as a result of centuries of English rule, as is the case in North America where their indigenous languages have been replaced by that of the colonists. As a consequence of national pride, anglicised names have been officially discouraged in many places: Ireland's Kingstown, named by King George IV, has reverted to its original Irish name of Dún Laoghaire; India's Bombay is now Mumbai, even though this is not the oldest local name (see Toponymy of Mumbai) and "Bombay" is still commonly used in the city; Calcutta is Kolkata, Dacca is Dhaka and Madras is Chennai Many Chinese endonyms have become de-anglicised: Canton is now more commonly called Guangzhou (廣州/广州), and Peking is generally referred to as Beijing (北京), although this reflected a name change from Beiping (Peiping) to Beijing (Peking)with the de-anglicisation of the name taking place after the name change to reflect a pronunciation change in Mandarin.
In other cases, established anglicised names have remained in common use where there is no national pride at stake: this is the case with Ghent (Gent/Gand), Munich (München), Cologne (Köln), Vienna (Wien), Naples (Napoli), Rome (Roma), Milan (Milano), Athens (Αθήνα/Athina), Moscow (Москва/Moskva), Saint Petersburg (Санкт-Петербург/Sankt-Peterburg), Warsaw (Warszawa), Prague (Praha), Bucharest (Bucureşti), Belgrade (Београд/Beograd), Lisbon (Lisboa) and other European cities whose names have been familiar in their anglicised forms for centuries. However, the de-anglicised names now often appear as an alternative on maps, in airports, etc.
Often the English name reflects a French origin, sometimes unchanged from French, e.g. Cologne, sometimes changed slightly, e.g. Vienna (Vienne), Venice (Venise). The English city-name for the Czech capital - 'Prague' is taken verbatim from the French name for the city, itself descended from the Latin name for the city (Praga), which had been borrowed from an earlier Czech name (pre-dating the 'g'>'h' shift).
Sometimes a place name can appear anglicised, but is not, such as when the form being used in English is an older name that has now been changed. For example, Turin in the Piedmont province of Italy was named Turin in the original Piedmontese language, but is now officially known as Torino in Italian. English-language media can sometimes overcompensate for this in the mistaken belief that the anglicised name was imposed by English speakers and is cultural domination. The International Olympic Committee made the choice to officially regard the city as "Torino" throughout the 2006 Winter Olympics.
The English/French name for Florence in Italy is closer to the original name in Latin (Florentia) than is the modern Italian name (Firenze).

Historical personal names
In the past, the names of people from other language areas were anglicised to a higher extent than today. This was the general rule for names of Latin or (classical) Greek origin. Today, the anglicised name forms are often retained for the more common persons, like Aristotle for Aristoteles, and Adrian or (later) Hadrian for Hadrianus. However, less well-known persons from the antiquity now are often given their full name (in the nominative case).
For royalty, the anglicisation of personal name was a general phenomenon, partly until recently: Charles for Carlos, Karoly, and Karl; Frederic for Friedrich or Fredrik, et cetera. For popes, anglicisation is still the rule: Pope John Paul II instead of Ioannes Paulus II, Pope Benedict XVI instead of Benedictus XVI.

Immigrant family and personal names
During the time in which there were large influxes of immigrants from Europe to the United States and United Kingdom during the 19th and 20th centuries, the names of many immigrants were changed. Many times this happened right at arrival, with the immigration officials mishearing and writing down whatever they heard, or was done by the immigrants to give themselves a more American or British sounding name.
French immigrants to the United States (both those of Huguenot and French Canadian background) often accommodated those unfamiliar with French pronunciations and spellings by altering their surnames in either of two ways: spellings were changed to fit the traditional pronunciation (Pariseau became Parizo, Boucher became Bushey, Mailloux became Mayhew), or pronunciations were changed to fit the spelling (Benoît, pronounced [bənwa], became /bɛnˈɔɪt/). In some cases, it could go either way (Gagné, pronounced [ɡaɲe], become /ˈɡæɡni/ or Gonyea), or something only slightly similar (Bourassa became Bersaw).
Most Irish names have been anglicised. A good example of this can be seen in the surnames of many Irish families – for example, Ó Briain has often become O'Brien, Ó Rothláin became Rowland, Ó Néill became O'Neill and some surnames like Ó Súilleabháin may be shortened to just O'Sullivan or Sullivan. Similarly, native Scottish names were altered such as Somhairle to Sorley, Mac Gill-Eain to MacLean, and Mac Aoidh to MacKay. Many Welsh names have also been altered, such as 'ap Hywell' to Powell, or 'ap Siôn' to Jones.
German names have also been anglicised (von Licht to Light) due to the German immigration waves during times of political instability in the late 19th century and early 20th century. A somewhat different special case was the politically motivated change of dynasty name in 1917 by the royal family of the United Kingdom to the House of Windsor.
The anglicisation of a personal name now usually depends on the preferences of the bearer. Name changes are less common today for Europeans emigrating to the United States than they are for people originating in East Asian countries. For instance, Xiangyun might be anglicised to Sean as the pronunciation is similar (though Sean - or Seán - is Irish and is a Gaelicisation of the Anglo-Norman Jean, which itself has been anglicised to John).

Ethnonyms
In some cases ethnonyms may be anglicised from a term in another language (either the language of the group described or the language of another people).

The anglicisation of other languages

A more recent linguistic development is anglicisation of other languages, in which words are borrowed from English; such a word is known as an anglicism. With the rise in Anglophone media and global spread of British and American cultures in the 20th and 21st centuries, many English terms have entered popular usage in other tongues. Technology-related English words like internet and computer are particularly common across the globe, as there are no pre-existing words for them. English words are sometimes imported verbatim, and sometimes adapted to the importing language in a process similar to anglicisation. In languages with non-Latin alphabets, these borrowed words can be written in the Latin alphabet anyway, resulting in a text made up of a mixture of scripts; other times they are transliterated. Transliteration of English and other foreign words into Japanese requires the special katakana script.
In some countries such anglicisation is seen as relatively benign, and the use of English words may even take on a chic aspect. In Japan marketing products for the domestic market often involves using English or pseudo-English brand names and slogans. In other countries, anglicisation is seen much more negatively, and there are efforts by public-interest groups and governments to reverse the trend; for example, the Académie française in France insists on the use of French neologisms to describe technological inventions in place of imported English terms.

Anglicisation of minority language groups

The adoption of English as a personal, preferred language is another form of anglicisation. Calvin Veltman, following the methods of analysis developed in Quebec, Canada for establishing rates of language shift, uses the term to refer to the practice of individuals in minority language groups who cease using their mother tongue as their usual, preferred language and adopt English instead. When such individuals continue to speak their mother tongue, they are referred to as "English-dominant bilinguals" and when they cease to do so, they are referred to as "English monolinguals". Rates of anglicisation may be calculated by comparing the number of people who usually speak English to the total number of people in any given minority language group.

American Idol Moving To New

As its tenth season nears, "American Idol" continues to shake things up.

Fox announced on Friday that in January the amateur-talent juggernaut will now air on Wednesdays and Thursdays after launching from a Tuesday-night slot for years. According to the network's 2010 to 2011 midseason schedule, Tuesdays will lead with "Glee" at 8 p.m., followed by "Raising Hope" and a new sitcom "Mixed Signals."

The lineup change is the latest in a slew of revamps to the Fox hit. The buzzed-about judges' panel was completely overhauled and now includes Jennifer Lopez and Steven Tyler alongside "Idol" veteran Randy Jackson. The minimum age limit was also lowered to 15. In addition, the show will no longer whittle down the finalists from 24 to 12, and instead just introduce a dozen singers for fans to vote for. Tenth-season hopefuls will also be tasked with crafting memorable visuals as part of a brand new music video competition.

Lythoe has dished on how Tyler and Lopez are approaching their new gigs, praising them for their serious take on the job. He also added that longtime critic Jackson is stepping up his game and providing pithy insight.

"Randy is pulling his weight," Lythgoe said recently. "He really has stepped up. He's essentially come out of himself. He's enjoying being in that position."

Lopez has also said that next season with show will be more forgiving with auditioners, and try not to let panicky nerves get in the way of recognizing a talented hopeful.

"I don't want to let anybody really great [not make it through] because they're nervous, and not get to see what they could have did," Lopez said in September. "They're going to come in here and be a little bit nervous in the beginning, and then you realize, 'Wow, that person is really talented.' So we work them a little bit more than maybe you've seen in the past. We've given them more of a chance."

Acid throwing

Acid throwing (acid attack or vitriolage) is a form of violent assault. Perpetrators of these attacks throw acid at their victims (usually at their faces), burning them, and damaging skin tissue, often exposing and sometimes dissolving the bones. The consequences of these attacks include blindness and permanent scarring of the face and body. These attacks are most common in Cambodia. Afghanistan, India, Bangladesh, Pakistan and other nearby countries. According to Taru Bahl and M.H. Syed, 80% of victims of these acid attacks are female and almost 40% are under 18 years of age.

Victims and treatment

There is a high survival rate amongst victims of acid attacks. Consequently the victim is faced with physical challenges, which require long term surgical treatment, as well as psychological challenges, which require in-depth intervention from psychologists and counsellors at each stage of physical recovery.
Depression and anxiety are common amongst all patients with large burn injuries; however for victims with acid injuries the physical scarring can lead to feelings of shame and embarrassment, resulting in the survivor living a life in hiding due to fear of prejudice and stigma from their peers and the community. Many survivors continue to have vivid memories of the incident which cause great levels of distress, especially when they know their attackers are free to attack again.
The Acid Survivors Foundation (ASF), Nairpokkho and Action Aid assist survivors in Bangladesh. The Acid Survivors Foundation in Pakistan (ASF-P) operates in Islamabad offering medical, psychological and rehabiliation support. The Acid Survivors Foundation in Uganda (ASF-U) operates in Kampala and also provides counselling and rehabilitation treatment to victims of acid attacks, as well as their families if need be. Additionally in Cambodia, LICADHO, the Association of the Blind in Cambodia and the Cambodian Acid Survivors Charity (CASC) all assist survivors of acid attacks. The Acid Survivors Trust International (ASTI) provides specialist support to its sister organisations in Africa and Asia through its specialist team who work across the organisations transferring medical, psychological and social rehabilitation skills whilst supporting knowledge sharing and best practice.

Attacks in South Asia

In South Asia, acid throwing attacks have been used as a form of revenge for refusal of sexual advances, proposals of marriage and demands for dowry. Scholars Taru Bahl and M.H. Syed say that land disputes are another leading cause. In Bangladesh, where such attacks are relatively common, they are mostly a form of domestic violence.Tom O'Neill of National Geographic reported that acid throwing is also used to enforce the caste system in modern India, where uppercaste individuals often attack Dalits for supposedly violating the order. In Cambodia, it was reported that these attacks were mostly carried out by wives against their husbands' lovers. According to New York Times reporter Nicholas D. Kristof, acid attacks are at an all time high in Pakistan and increasing every year. The Pakistani attacks he describes are typically the work of husbands against their wives who have "dishonored them". In India, the number of acid attacks have been rising. There had been 68 reported acid attacks in the state of Karnataka since 1999.
According to a Rand Corporation commentary, hundreds of women in Pakistan, Kashmir and Afghanistan have been blinded or maimed "when acid was thrown on their unveiled faces by male fanatics who considered them improperly dressed". Attacks or threats of attacks on women who failed to wear hijab or were otherwise "immodestly dressed" have been reported in other countries as well. In Afghanistan in November 2008, extremists also targeted women (schoolgirls) in acid attacks for attending school. During the Taliban's rule, girls were banned from school.
The chemical agents most commonly used to commit these attacks are hydrochloric acid and sulphuric acid. According to Mridula Bandyopadhyay and Mahmuda Rahman Khan, it is a form of violence primarily targeted at women. They describe it as a relatively recent form of violence, with the earliest record in Bangladesh from 1983. The scholar Afroza Anwary points out that acid violence occurs not only in Bangladesh but also in Pakistan, China, Ethiopia and has occurred historically in Europe.

Legislation
In 2002, Bangladesh introduced the death penalty for throwing acid and laws strictly controlling the sales of acids.
Under the Qisas law of Pakistan, the perpetrator may suffer the same fate as the victim, and may be punished by having drops of acid placed in his eyes. This law is not binding and is rarely enforced according to a New York Times report. Iran has a similar law, and sentenced an attacker to be blinded in 2008.

Skin grafting

Walter Yeo, a British soldier, is assumed to be the first person to be benefited from plastic surgery employing tubed pedicle flaps, performed by Sir Harold Gillies in 1917. Before (left) and after (right) the operation.
Skin grafting is a type of medical grafting involving the transplantation of skin. The transplanted tissue is called a skin graft.

Skin grafting is often used to treat:
Extensive wounding or trauma
Burns
Areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans
Specific surgeries that may require skin grafts for healing to occur
Skin grafts are often employed after serious injuries when some of the body's skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: it can reduce the course of treatment needed (and time in the hospital), and it can improve the function and appearance of the area of the body which receives the skin graft. There are two types of skin grafts, the more common type is where a thin layer is removed from a healthy part of the body (the donor section) like peeling a potato (see donor section), or a full thickness skin graft, which involves pitching and cutting skin away from the donor section. A full thickness skin graft is more risky, in terms of the body accepting the skin, yet it leaves only a scar line on the donor section, similar to a Cesarean section scar. For full thickness skin grafts, the donor section will often heal much more quickly than the injury and is less painful than a partial thickness skin graft.

Graft taxonomy

Autologous: The donor skin is taken from a different site on the same individual's body (also known as an autograft).
Isogeneic: The donor and recipient individuals are genetically identical (e.g., monozygotic twins, animals of a single inbred strain; isograft or syngraft).
Allogeneic: The donor and recipient are of the same species (human→human, dog→dog; allograft).
Xenogeneic: The donor and recipient are of different species (e.g., bovine cartilage; xenograft or heterograft).
Prosthetic: Lost tissue is replaced with synthetic materials such as metal, plastic, or ceramic (prosthetic implants).

Graft classification

Skin grafts can be
Split-thickness - epidermis and variable amounts of dermis. Commonly taken from the thigh or buttocks. The donor site heals by re-epitheliasation from the dermis and surrounding skin and requires dressings.
Full - thickness- epidermis and all the dermis. The donor site is either sutured directly or split-thickness skin grafted.
Composite graft - small grafts containing skin and underlying cartilage or other tissue. Donor sites include, for example, ear skin and cartilage to reconstruct nasal alar rim defects.

Donor selection


Skin Graft Donor site 8 days after the skin was taken

When grafts are taken from other animals, they are known as heterografts or xenografts. By definition, they are temporary biologic dressings which the body will reject within days to a few weeks. They are useful in reducing the bacterial concentration of an open wound, as well as reducing fluid loss.
For more extensive tissue loss, a full-thickness skin graft, which includes the entire thickness of the skin, may be necessary. This is often performed for defects of the face and hand where contraction of the graft should be minimized. The general rule is that the thicker the graft, the less the contraction and deformity.
Cell cultured epithelial autograft (CEA) procedures take skin cells from the patient to grow new skin cells in sheets in a laboratory. The new sheets are used as grafts, and because the original skin cells came from the patient, the body does not reject them. Because these grafts are very thin (only a few cell layers thick) they do not stand up to trauma, and the "take" is often less than 100%. Newer grafting procedures combine CEA with a dermal matrix for more support. Research is investigating the possibilities of combining CEA and a dermal matrix in one product.

Surgical procedure

In order to remove the thin and well preserved skin slices and stripes from the donor, surgeons use a special surgical instrument called a dermatome. This usually produces a split-thickness skin graft, which contains the epidermis with only a portion of the dermis. The dermis left behind at the donor site contains hair follicles and sebaceous glands, both of which contain epidermal cells which gradually proliferate out to form a new layer of epidermis. The donor site may be extremely painful and vulnerable to infection.
The graft is carefully spread on the bare area to be covered. It is held in place by a few small stitches or surgical staples. The graft is initially nourished by a process called plasmatic imbibition in which the graft literally "drinks plasma". New blood vessels begin growing from the recipient area into the transplanted skin within 36 hours in a process called capillary inosculation. To prevent the accumulation of fluid under the graft which can prevent its attachment and revascularization, the graft is frequently meshed by making lengthwise rows of short, interrupted cuts, each a few millimeters long, with each row offset by half a cut length like bricks in a wall. In addition to allowing for drainage, this allows the graft to both stretch and cover a larger area as well as to more closely approximate the contours of the recipient area. However, it results in a rather pebbled appearance upon healing that may ultimately look less aesthetically pleasing.
An increasingly common aid to both pre-operative wound maintenance and post-operative graft healing is the use of negative pressure wound therapy (NPWT). This system works by placing a section of foam cut to size over the wound, then laying a perforated tube onto the foam. The arrangement is then secured with bandages. A vacuum unit then creates negative pressure, sealing the edges of the wound to the foam, and drawing out excess blood and fluids. This process typically helps to maintain cleanliness in the graft site, promotes the development of new blood vessels, and increases the chances of the graft successfully taking. NPWT can also be used between debridement and graft operations to assist an infected wound in remaining clean for a period of time before new skin is applied. Skin grafting can also be seen as a skin transplant


Skin graft on lower leg trauma injury, some 5 days after surgery. Take and healing aided by use of Vacuum Assisted Closure.

Risks

Risks for the skin graft surgery are:
Bleeding
Infection
Loss of grafted skin
Nerve damage
Graft-versus-host disease
Rejection may occur in xenografts. To prevent this, the patient usually must be treated with long-term immunosuppressant drugs.

Prognosis

Most skin grafts are successful, but in some cases they do not heal well and require repeat grafting. The graft should also be monitored for good circulation. The recovery from surgery is usually rapid after split thickness skin grafting. The skin graft must be protected from trauma or significant stretching for 2-3 weeks. Depending on the location of the graft, a dressing may be necessary for 1-2 weeks. Exercise that might stretch or injure the graft should be avoided for 3-4 weeks.

Chelsea and Westminster Hospital

Chelsea and Westminster Hospital is a public hospital located on Fulham Road, in the Chelsea area of London, England.

History

The new Chelsea and Westminster Hospital was opened on the site once occupied by St Stephen's Hospital, and brought together staff, services and equipment from five London hospitals:
The Westminster hospital in Horseferry Road (previously situated opposite Westminster Abbey) and its medical school in Page Street
Westminster Children's hospital , originally in Vincent Square, then later amalgamated with the Westminster
West London hospital, opened in 1860 and known from the early 1970s for its maternity services
St Mary Abbots hospital, an infirmary occupying the site of what had been the Kensington work house
St Stephen's hospital
The Chelsea and Westminster Hospital was designed by the architects Sheppard Robson. The hospital displays many treasures from the old hospitals. Some of these are in the first floor Hospital Chapel, including an 16th century painting by Veronese from the Westminster Hospital and stained glass windows from Westminster , St Mary Abbots and the Westminster Children's Hospitals.
The hospital is managed by the Chelsea and Westminster Hospital NHS Foundation Trust.

Services

Chelsea and Westminster maintains a full range of medical and surgical acute services, as well as outpatient facilities and a 24 hour Accident and Emergency department. In addition to these services, which are primarily aimed at local residents and visitors, the hospital is a specialist tertiary referral centre for a number of services including HIV and Genitourinary Medicine, Burns and Bariatric Surgery.

Hand Trauma
The hospital provides a number of services which include a specialist hand surgery/management unit sometimes known as HMU.
Access to these services is often made via GP referral. However, various A&E departments can make urgent tertiary referrals.

HIV / GUM
The hospital’s HIV / GUM Clinical Directorate was established in April, 1991 , and is today the largest specialist HIV unit in Europe , caring for more than 5,000  HIV patients, and enjoys a worldwide reputation as a centre of excellence in both the care of HIV-positive patients and a wide range of associated clinical research. Its director, Professor Brian Gazzard , is one of the world's leading authorities on HIV, founded the British HIV Association, serves as Chairman of the British HIV Guidelines Writing Committee, and is a member of both the Scientific Committee of the World AIDS Congress and of the IAS USA Guidelines Committee.
The St Stephen’s Centre at Chelsea & Westminster Hospital is also home to the core laboratory of the International AIDS Vaccine Initiative (IAVI). 

Education

In 1984, Westminster Hospital Medical School merged with the Charing Cross Hospital Medical School to form Charing Cross and Westminster Medical School. This was part of a series of mergers of London medical schools in the early 1980s, foreshadowing a larger series in the late 1990s, which brought all the institutes together into five large schools. In 1997, as part of the second wave, CXWMS merged with Imperial College, London (and its medical department, St Mary's Hospital Medical School), the National Heart and Lung Institute, and the Royal Postgraduate Medical School, to form Imperial College School of Medicine
Chelsea & Westminster Hospital maintains strong ties with Imperial College School of Medicine and is a teaching hospital for students undergoing clinical attachments in various specialties.

Trust

The Chelsea and Westminster Hospital NHS Foundation Trust was formed on 1 October 2006[8]. It is based at the Chelsea and Westminster Hospital and also manages a number of sexual health clinics at 56 Dean Street, the West London Centre for Sexual Health at Charing Cross Hospital, and the St Stephen's Centre. The Trust's chief executive is Heather Lawerence and its chairman is Professor Sir Christopher Edwards.

Channel 4

Channel 4 is a British public-service television broadcaster which began working on 2 November 1982. Although largely commercially self-funded, it is ultimately publicly owned; originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by the Channel Four Television Corporation, a public body established in 1990, coming into operation in 1993. With the conversion of the Wenvoe transmitter in Wales to digital on 31 March 2010, Channel 4 became a national TV channel, after almost 28 years.
The channel was established to provide a fourth television service to the United Kingdom that would break the duopoly of the Television licence-funded BBC's two established services and the single commercial broadcasting network, ITV. Channel 4 enjoys almost universal coverage in the United Kingdom and some neighbouring countries and a significant audience share, despite having seen new competition with the growth of cable, satellite and digital services.

Public service remit

Channel 4 was established with, and continues to hold, a remit of public service obligations which it must fulfil. The remit changes periodically, as dictated by various broadcasting and communications acts, and is regulated by the various authorities Channel 4 has been answerable to; originally the IBA, then the ITC and now Ofcom.
The preamble of the remit as per the Communications Act 2003 states that:
"The public service remit for Channel 4 is the provision of a broad range of high quality and diverse programming which, in particular:
demonstrates innovation, experiment and creativity in the form and content of programmes;
appeals to the tastes and interests of a culturally diverse society;
makes a significant contribution to meeting the need for the licensed public service channels to include programmes of an educational nature and other programmes of educative value; and
exhibits a distinctive character."
The remit also involves an obligation to provide programming for schools,and a substantial amount of programming produced outside of Greater London.

Channel Four Television Corporation

As an organisation, Channel 4 is known as the Channel Four Television Corporation (sometimes abbreviated to C4C), a statutory corporation, though this form is more recent than the station itself, having previously been the Channel Four Television Company Limited, a subsidiary of the IBA, between 1982 and 1993.
Towards the end of the 1980s, the government began a radical process of re-organisation of the commercial broadcasting industry, which was written onto the statute books by means of the Broadcasting Act 1990. Significantly, this meant the abolition of the IBA, and hence the Channel Four Television Company. The result led to the creation of a corporation to own and operate the channel, which would have a greater deal of autonomy and would eventually go on to establish its other operations. The new corporation, which became operational in 1993, remained publicly owned and was regulated by the new Independent Television Commission (ITC), created under the same act. The ITC and its duties were later replaced by Ofcom, which like its predecessor is responsible for appointing the Corporation's board, in agreement with the Secretary of State for Culture, Media and Sport.
In terms of the station's remit and other duties, the creation of the corporation meant little change; the new corporation would have to manage its own advertising, rather than this being carried out on its behalf by the local ITV contractors (see Funding).

History

Wales
 S4C
At the time the fourth service was being considered, a movement in Wales lobbied for the creation of dedicated service that would air Welsh-language programmes, then only catered for at 'off peak' times on BBC Wales and HTV. The campaign was taken so seriously by Gwynfor Evans, former president of Plaid Cymru, that he threatened the government with a hunger strike were it not to honour the plans.
The result was that Channel 4 as seen by the rest of the United Kingdom would be replaced in Wales by "Sianel Pedwar Cymru" or "Channel 4 Wales". Operated by a specially created Welsh Fourth Channel Authority, S4C would air programmes in Welsh as made by HTV, the BBC, or from independent companies. Initially limited frequency space meant that Channel 4 proper could not be broadcast alongside S4C, though some English Channel 4 programmes would be aired at less popular times on the Welsh variant, a practice that carried on up until the closure of S4C's analogue transmissions in 2010.
Since then, carriage on digital cable, satellite and digital terrestrial has introduced Channel 4 to Welsh homes where it is now universally available.

Conception
Before Channel 4 and S4C, Britain had three terrestrial television services: BBC1, BBC2, and ITV. The Broadcasting Act 1980 began the process of adding a fourth, and Channel 4, along with its Welsh counterpart, was formally created by an Act of Parliament in 1982. After some months of test broadcasts, it began scheduled transmissions on 2 November 1982.
The notion of a second commercial broadcaster in the United Kingdom had been around since the inception of ITV in 1954 and its subsequent launch in 1955; the idea of an 'ITV2' was long expected and pushed for. Indeed television sets sold throughout the 1970s and early 1980s had a spare channel called 'ITV/IBA 2'. Throughout ITV's history and until Channel 4 finally became a reality, a perennial dialogue existed between the GPO, the government, the ITV companies and other interested parties, concerning the form such an expansion of commercial broadcasting would take. It was most likely politics which had the biggest impact in leading to a delay of almost three decades before the second commercial channel became a reality.With what can crudely be summed up as a clash of ideologies between an expansion of ITV's commercial ethos and a public service approach more akin to the BBC, it was ultimately somewhat of a compromise that eventually led to the formation of Channel 4 as launched in 1982.
One clear benefit of the 'late arrival' of the channel was that its frequency allocations at each transmitter had already been arranged in the early 1960s, when the launch of an ITV2 was highly anticipated. This led to very good coverage across most of the country and few problems of interference with other UK-based transmissions; a stark contrast to the problems associated with Five's launch 14 and a half years later.

The first voice ever heard on Channel 4's opening day of Tuesday 2 November 1982 was that of continuity announcer Paul Coia, who intoned, "Good afternoon. It's a pleasure to be able to say to you: Welcome to Channel Four", before heading into a montage of clips from its programmes set to the station's signature tune, "Fourscore", written by Lord David Dundas, which would form the basis of the station's jingles for its first decade. The first programme to air on the channel was the teatime game show Countdown, at 16.45 produced by Yorkshire Television; it is still running as of 2010. The first person to be seen on Channel 4 was Richard Whiteley with Carol Vorderman being the second and the first female on the channel. Whiteley opened the show with the words "As the countdown to a brand new channel ends, a brand new countdown begins." On its first day, Channel 4 also broadcast controversial soap opera Brookside, which ran for 21 years.
Upon its launch, Channel 4 committed itself to providing an alternative to the existing channels, an agenda in part set out by its remit which required the provision of programming to minority groups.
In step with its remit, the channel became well received both by minority groups and the arts and cultural worlds during this period, especially under Isaacs, where the channel gained a reputation for programmes on the contemporary arts. The channel often did not receive mass audiences for much of this period, however, as might be expected for a station focusing on minority interest.
Channel 4 also began the funding of independent films, such as the Merchant-Ivory docudrama The Courtesans of Bombay, during this time.
In 1992, Channel 4 also faced its first libel case by Jani Allan, a South African journalist, who objected to her representation in the documentary The Leader, His Driver and the Driver's Wife.

After control of the station passed from the Channel Four Television Company to the Channel Four Television Corporation in 1993 (see above), a shift in broadcasting style took place. Instead of aiming for the fringes of society, it began to focus on the edges of the mainstream, and the centre of the mass market itself[citation needed]. It began to show many US programmes in peak viewing time, far more than it had previously done. It premièred such shows as Friends and ER.
In the early 2000s, Channel Four began broadcasting reality formats such as Big Brother and obtained the rights to broadcast mass appeal sporting events like cricket and horse racing. This new direction increased ratings and revenues.
In addition, the channel launched a number of new television channels through its new 4Ventures off-shoot, including Film4, At The Races, E4 and More4 (see Other services).
Partially in reaction to its new 'populist' direction, the Communications Act 2003 directed the channel to demonstrate innovation, experimentation and creativity, appeal to the tastes and interests of a culturally diverse society and to include programmes of an educational nature which exhibit a distinctive character.
Under the leadership of Freeview founder Andy Duncan, 2005 saw a change of direction for Channel 4's digital channels. Channel 4 made E4 'free to air' on Digital Terrestrial, and launched a new 'free to air' digital channel called More4. By October, Channel 4 had joined the Freeview consortium. By July 2006, Film4 had also become a 'free to air' and re-started broadcasting on Digital Terrestrial.
Venturing into radio broadcasting, 2005 saw Channel 4 purchase 51 per cent of shares in the now defunct Oneword radio station with UBC Media holding on to the remaining shares. New programmes such as the weekly, half-hour The Morning Report news programme were among some of the new content Channel 4 provided for the station, with the name 4Radio being used. As of early 2009, however, Channel 4's future involvement in radio remained uncertain.

On 2 November 2007, the station celebrated its twenty-fifth birthday. It showed the first episode of Countdown, an anniversary Countdown special, as well as a special edition of The Big Fat Quiz and using the original multicoloured 1982-1996 blocks logo on presentation and idents using the Fourscore jingle throughout the day.

In November 2009, Channel 4 launched a week of 3D television, broadcasting selected programmes each night using stereoscopic ColorCode technology. The accompanying 3D glasses were distributed through Sainsbury's supermarkets.

The future
Channel 4 has raised concerns over how it might finance its public service obligations after digital switch-over. However, some certainty lies in the announcement in April 2006 that Channel 4's digital switch-over costs would be paid for by licence fee revenues.
On 28 March 2007, Channel 4 announced plans to launch a music channel "4Music" as a joint venture with British media company EMAP which would include carriage on the Freeview platform. On 15 August 2008, 4Music was launched across the UK. Recently, Channel 4 have announced interest in launching a high-definition version of Film4 on Freeview, to coincide with the launch of Channel 4 HD, however the fourth HD slot was given to Five instead. Channel 4 has since acquired a 50% stake in EMAP's TV business for a reported £28 million.

Carriage

Channel 4 was carried from its beginning on analogue terrestrial (except in Wales), which was practically the only means of television broadcast in the United Kingdom at the time. It will continue to be broadcast through these means until the changeover to digital terrestrial television in the United Kingdom is complete. Since 1998, it has been universally available on digital terrestrial, and the Sky platform (encrypted, though free of charge) as well as having been available from various times in various areas, on analogue and digital cable networks.
Due to its special status as a public service broadcaster with a specific remit, it is afforded free carriage on the terrestrial platforms, in contrast with other broadcasters such as ITV.
Channel 4 is also available overseas: some viewers in Ireland and parts of the European mainland have been able to receive terrestrial transmissions from the United Kingdom, and some overseas cable networks, especially in Ireland, have carried the service. From 4 December 2006 Channel 4 was officially available to Sky viewers in Ireland; some programmes, mainly imports, are not aired on this channel variant, due to Channel 4 not owning the relevant broadcast rights within the country.
Channel 4 allowed Internet users in the United Kingdom to watch Channel 4 live on the Internet[citation needed]. However some programmes (mostly international imports) were not shown and this service no longer exists. Channel 4 is also provided by Virgin Mobile's DAB mobile TV service which has the same restrictions as the Internet live stream had.
Channel 4 also makes some of its programming available "on demand" via cable and the Internet (see 4oD).


Funding

During the station's formative years, funding came from the ITV companies in return for their right to sell advertisements in their region on the fourth channel.
Nowadays it pays for itself in much the same way as most privately run commercial stations, i.e. through the sale of on-air advertising, programme sponsorship, and the sale of any programme content and merchandising rights it owns, such as overseas sales and video sales. It also has the ability to subsidise the main network through any profits made on the corporation's other endeavours, which have in the past included subscription fees from stations such as E4 and Film4 (now no longer subscription services) and its 'video-on-demand' sales. In practice, however, these other activities are loss-making, and are subsidised by the main network. According to Channel 4's last published accounts, for 2005, the extent of this cross-subsidy was some £30 million.
The change in funding method came about by the Broadcasting Act 1990 when the new corporation was afforded the ability to fund itself. Originally this arrangement left a 'safety net' guaranteed minimum income should the revenue fall too low, funded by large insurance payments made to the ITV companies. Such a subsidy was never required, however, and these premiums were phased out by government in 1998. After the link with ITV was cut, the cross-promotion which had existed between ITV and Channel 4 also ended.
In 2007 due to severe funding difficulties, the channel sought government help and was granted a payment of £14 million over a six-year period. The money would have come from the television licence fee and would have been the first time that money from the licence fee had been given to any broadcaster other than the BBC. The plan was scrapped by The Secretary of State for Culture, Media and Sport, Andy Burnham, ahead of "broader decisions about the future framework of public service broadcasting". The broadcasting regulator Ofcom released their review in January 2009 in which they suggested that Channel 4 would preferably by funded by "partnerships, joint ventures or mergers".

Programming

 Channel 4 programming


Channel 4 share of viewing 1992-2007 BARB figures. Peaks from mid-2000 coincide with broadcast of Endemol's Big Brother and Celebrity Big Brother
Channel 4 is a "publisher-broadcaster", meaning that it commissions or "buys" all of its programming from companies independent of itself, and was the first broadcaster in the United Kingdom to do so on any significant scale. This had the consequence of starting an industry of production companies that did not have to rely on owning an ITV licence in order to see their programmes air, though since Channel 4, external commissioning has become regular practise on the numerous stations that have launched since, as well as on the BBC and in ITV (where a quota of 25% minimum of total output has been imposed since the 1990 Broadcasting Act came into force). Ironically, having been the first British broadcaster to completely commission its core product from third parties, and after 25 years in-house, Channel 4 will now become the last terrestrial broadcaster to outsource its transmission and playout operations (to Red Bee Media).
The requirement to obtain all content externally is stipulated in its licence.Additionally, Channel 4 also began a trend of owning the copyright and distribution rights of the programmes it aired, in a manner that is similar to the major Hollywood studios' ownership of television programs that they did not directly produce. Thus, although Channel 4 does not produce programmes, many are seen as belonging to it.
Channel 4 also pioneered the concept of stranded programming, where seasons of programmes following a common theme would be aired and promoted together. Some would be very specific, and run for a fixed period of time; the 4 Mation season, for example, showed innovative animation. Other, less specific strands, were (and still are) run regularly, such as T4, a strand of programming aimed at teenagers, on weekend mornings (and weekdays during school/college holidays); Friday Night Comedy, a slot where the channel would pioneer its style of comedy commissions, 4Music (now a separate channel) and 4Later, an eclectic collection of offbeat programmes transmitted to a cult audience in the early hours of the morning.
In its earlier years, Red Triangle was the name given to the airing of certain risqué art-house films due to the use of a red triangle DOG in the upper right of the screen, dubbed as being pornographic by many of Channel 4's critics, whilst general broadcasting of films on the station for many years came under the banner of Film on Four prior to the launch of the FilmFour brand and station in the late 1990s.
Its critically acclaimed news service, Channel 4 News, is supplied by ITN whilst its long-standing investigative documentary, Dispatches, causes perennial media attention.


Other services

November 1998 saw Channel 4 expand beyond its remit of providing the 'fourth service' in a significant way, with the launch of FilmFour. Since then the corporation has been involved in a range of other activities, all in some way associated with the main channel, and mainly using the '4' brand.
In March 2010 these additional services were reviewed by the government's Culture, Media and Sport select committee. The channel and its Chief Executive were criticised for breaking service commitments, a lack of transparency in accounting for digital channels, poor governance and failed investments

4Ventures/4Rights
In 2001 4Ventures was created as the parent body of Channel 4 related commercial activities, rather than public-service obligations, with the intent of making profit which would serve to subsidise the main Channel 4.
Following the sale of Quiz Call (a gaming channel operated by the then-owned subsidiary Ostrich Media) in 2006, a restructure of 4Ventures saw many of its activities re-integrated back into the main channel's operations (including day-to-day running of E4, Film4 and More4).
4Rights, was formed from an amalgamation of Channel 4 International and Channel 4 Consumer Products. As part of the restructure, much of the 4Ventures management team either left the company - former chief executive (and Channel 4 commercial director) Rob Woodward, and managing director Anmar Kawash are now Chief Executive Officer and Chief Operating Officer respectively of STV Group plc - or transferred to other posts within Channel 4.
In 2007, the expanding, UK-based, independent distribution group Digital Rights Group (DRG) announced an intention to buy Channel 4 International (adding it to Zeal and ID Distribution among its other companies), following a review by Channel 4 of its commercial division. The deal was completed in November of the same year. The Consumer Products division has been retained by Channel 4 as part of a new, restructured, 4Rights division.


Television


Channel 4 digital channels viewing figures 1998-2008

]Film4

Channel 4 has had a long record of success in funding the production of films through Channel Four Films, renamed FilmFour in 1998 to coincide with the launch of its digital channel of the same name. Notable successes include The Madness of King George, The Crying Game and Four Weddings and a Funeral. However, this dedicated film-making wing was scaled back in 2002 as a cost-cutting measure in the face of substantial losses.
Channel 4 launched a subscription film channel, FilmFour, in November 1998. It was available on digital satellite television and digital cable. Companion services, such as FilmFour+1, FilmFour World and FilmFour Extreme were also available on some digital services. In 2003 Extreme and World were discontinued, and replaced with FilmFour Weekly. FilmFour Weekly closed in July 2006, when the main, newly named Film4 channel went free-to-view and became available on Digital Terrestrial. The switchover to digital terrestrial was heavily advertised. The adverts featured Lucy Liu, Christian Slater, Ewan McGregor, Judi Dench, Gael García Bernal, Willem Dafoe, Mackenzie Crook, Rhys Ifans and Ray Winstone declaring "Film4 is now free" in various situations across London. It remains the only film channel available free on digital terrestrial television.
In 2002, Channel 4's film financing division (Film4 Productions) was seriously scaled back, due to massive losses, although total closure was averted. It had however had various successes, most notably Four Weddings and a Funeral and Trainspotting. In 1994, BAFTA/LA (the Los Angeles branch of the British Academy of Film & Television Arts) presented a full-length film festival in Los Angeles in conjunction with the American Cinematheque (the US equivalent of Britain's National Film Theatre) that saluted the considerable contributions to British film of Channel 4's film division since its inception. The festival presented many of the most celebrated Channel 4 films, and also featured panel discussions about Channel 4's role between Channel 4 chief executive Michael Grade and US TV producer Norman Lear.
When Channel 4 had the rights to broadcast test match cricket in England, the downtime of the FilmFour channel was often used to broadcast uninterrupted coverage of a match when the main channel was committed elsewhere, usually to racing. At these times FilmFour was available unencrypted and free-to-air.

E4
: E4 (channel)
E4, a digital entertainment channel previously available on the Internet, with a target age-range of 16-34, was launched in January 2001. It features premières of US imports and supplementary footage for programmes on its main channel (most notably extended Big Brother coverage).
In 2005 it launched on Digital Terrestrial. E4 now has as much coverage as other services available on Cable, Satellite and Digital Terrestrial like ITV2 and BBC Three. It is a very successful channel with a first look or sneak peek, with the next episode of some series, such as Hollyoaks and Desperate Housewives appearing on E4 immediately after the show on Channel 4 has finished. Also they have "Second Chance Sunday" which allows you to see programmes you have missed during the week on a Sunday. New show Skins was a massive success for E4, peaking at the 2 million mark - one of the most viewed premières in digital TV history. There has, however, been some criticism that E4 (like many other digital channels), relies on seemingly endless repeats of a small selection of shows (notably Friends), with further suggestion that it is often the same season of a particular show that is endlessly repeated.[citation needed]
During Big Brother, E4 plays host to live coverage of the show, subject to a delay. Until 2005, programmes on the channel didn't air until 14.00 GMT, but on 12 August 2005 the widely-advertised E4 Music airs from 06.00 until 10.00 GMT, with various music shows and videos being showcased. This however is rested during Big Brother. Transmission of E4 Music has since declined and has been replaced with repeats of popular E4 shows. It has been declared that E4 Music has been moved permanently to the new 4Music channel. Since 2008, live coverage of Big Brother has been shortened during the day.
E4 is widely available in Ireland in close to 70% of homes. It is carried on the NTL / Chorus cable networks and also on Sky. The channel operates a separate advertising opt-out in Ireland allowing advertisers to directly target Irish audiences. This has been a highly successful commercial operation and all airtime sales are handled on the channels behalf by Medialink in Dublin.

More4
More4 is a channel aimed at those aged 35–60. Launched on 10 October 2005, it channel carries news and nightly discussion programmes, such as More4 News, an extension of Channel 4 News that attempts to look "beyond the headlines", giving in-depth analysis. Advertising before the launch of the channel flaunted such HBO shows as Curb Your Enthusiasm and The Sopranos, as well as NBC's The West Wing. Its conception has met conflicting responses; many people believe the programmes shown to be of great quality, while others see it as an excuse to free up more room for a deluge of property programmes or less respectable programmes (see Fat Pets) in all other free slots on Channel 4.

4Music
Over recent years 4Music has risen, showing new single releases, as well as other music shows frequently broadcast across T4, Channel 4 and E4. 2007 saw its own logo being devised and since then has had many themed weekends dedicated to a current band or performer.
On Sundays, Channel 4's 4Music strand aired between 17:00 and midnight on The Hits. The first 'episode' was presented by the most successful female act of the century Sugababes, however 4Music Sundays were meant to feature live acts and also The Shockwaves Album Chart Show.
On 20 February 2008, it was announced that The Hits was to be rebranded as 4Music later in the year, and on 15 August 2008, Channel 4 replaced The Hits with 4Music. 4Music is available on Sky 360, Virgin 330 and Freeview 18. (See Box Television)
4Music also has its own monthly music magazine show, The Crush. Which is hosted by Rick Edwards.

'+1' Channels


Channel 4 "+ 1" logo.
Channel 4 runs timeshift variants of all its services (excluding 4Music and Channel 4 HD), including Channel 4 +1 since 20 August 2007. across all digital platforms. Channel 4 is the only terrestrial broadcaster in the United Kingdom to offer a time-shift variant of its main channel. In common with many other broadcasters, these channels output exactly the same programmes and continuity as was broadcast an hour previously, and are titled with the station name followed by a "+1" suffix.
Channel 4 +1, E4 +1 and More4 +1 all carry a "+1" indication onscreen. There was some concern[who?] about how it would be indicated on Channel 4 +1 as Channel 4 doesn't carry its own on-screen graphic. Eventually, a "+1" symbol that is derived from the Channel 4 logo was unveiled. Neither Film4 nor Film4 +1 carry on-screen graphics.

Box Television
In July 2007 Channel 4 bought 50% of Box Television Ltd for £28 m from Emap plc. It has since emerged that, as a result of Emap's decision to sell off its divisions in a break-up sale of the group, Channel 4 may be interested in acquiring the remaining half of the business. Box TV operates seven music TV stations (4Music, The Box, Smash Hits, Kerrang!, Q, Kiss and Magic). Emap's stake in Box Television Limited was transferred to new owners, Bauer Consumer Media, following Bauer's acquisition of Emap's publishing and radio businesses.

Channel 4 HD


On 10 December 2007, Channel 4 launched a high definition television simulcast of Channel 4 on Sky+ HD, after British Sky Broadcasting agreed to contribute toward the channel’s satellite distribution costs It is planned to roll out on other platforms "in the future". On 31 July 2009, Virgin Media added Channel 4 HD on channel 146 as a part of the M pack. On 25 March 2010 Channel 4 HD appeared on Freeview channel 52 with a placeholding caption, ahead of a commercial launch on 30 March 2010, coinciding with the commercial launch of Freeview HD.
The channel carries the same schedule as Channel 4, broadcasting programmes in HD when available. Initially this has been mostly American imports (such as Ugly Betty for example) and movies, however, original programming such as Hollyoaks and Skins have been broadcast in HD. Although the intention is to increase the amount of "home grown" material being broadcast in HD. It has been announced as the UK's first full-time high definition channel from a terrestrial broadcaster.
Previously, in the summer of 2006, Channel 4 ran a six month closed trial of HDTV, as part of the wider Freeview HD experiment via the Crystal Palace transmitter to London and parts of the home counties, including the use of Lost and Desperate Housewives as part of the experiment, as US broadcasters such as ABC already have an HDTV back catalogue.

Previous channels
At the Races
In 2000, Channel 4 launched a dedicated horse racing channel, At the Races. The channel ceased broadcasting in 2003. It was subsequently bought by British Sky Broadcasting and relaunched in June 2004. Channel 4 has no involvement with the new At The Races, which is branded with almost identical livery as Sky Sports. Channel 4's racing coverage, re-named to incorporate "At The Races" in the title, returned to its original name of Channel 4 Racing when the channel left involvement with At The Races. Channel 4 racing programmes now feature close co-operation with rival digital racing channel Racing UK, who sub-licence the live rights and share the same production company. Channel 4 cross-promote Racing UK's coverage of the day's racing during its broadcasts.

Radio
4 Digital Group
Channel 4 was the leading member of the 4 Digital Group consortium, which includes EMAP, UTV and STV Group plc as partners (although STV's involvement will cease when Virgin Radio is floated as a separate company). In July 2007 The group was awarded the 12 year licence to operate the second national DAB radio licence after having defeated its only rival, National Grid Wireless, in the three-month bidding process.
The service would have operated ten radio stations, including Channel 4 Radio, E4 Radio, Sky News Radio (operated by BSkyB and Global Radio) and Radio Disney (in association with Disney). Many of the services, especially Channel 4 Radio and E4 Radio would have competed directly with national BBC Radio stations. Podcast and text services were also to have been provided.[38] In October 2008 Channel 4 announced that it was abandoning its plans for digital radio stations.

4radio

In June 2006 Channel 4 tried to launch 4radio, offering audio programmes in the shape of podcasts aimed at introducing new public service radio services informed by C4's values of creativity and innovation. Coupled with its strategy of becoming a truly multimedia company, 4radio hosts shows that tie in with its flagship TV hits including Big Brother, Lost, and Channel 4 News.
The successful multiplex consortium was expected to launch in 2008 with a taste of Channel 4 Radio's audio output made available earlier, including a revival of the channel's The Tube music programme, and a very small amount of 4radio-branded content was heard on Oneword until its closure in January 2008.
Channel 4, as part of its review of public serving spending in 2008 decided to focus its expenditure on TV content and decided to stop its radio plans, resulting in the closure of 4 Digital Group.

Oneword
Oneword was a digital radio station featuring the spoken word. In early 2005 Channel 4 purchased a minority stake in it, later that year buying a majority one worth £1,000,000. On 4 January 2007 it was announced that had Channel 4 sold its 51% stake back to UBC Media for £1. Its normal programming was suspended while a strategic review took place on the station. The station ceased broadcasting on 11 January 2008.

Channel4.com
The station's website is channel4.com. The site offers detailed programme information, highlights, and chats with actors and presenters of all Channel 4 channels. It also has in-depth sections including news, film, homes, sport, and more. Its learning sections are often used by many for educational needs.

Internet
4mations
In January 2008, Channel 4 joined with Aardman Animations and Lupus Films to create 4mations, a user-generated content animation portal, similar to aniBOOM or MyToons.

4oD / Catch-up


4oD Logo
Launched in November 2006, 4oD stands for "4 on Demand", an Internet Television service which allows Internet (e.g. via SeeSaw, Virgin Media, TalkTalk TV and BT Vision) users to view programming recently shown on Channel 4, E4 or More4, or from their archives. The cable and IPTV versions is operated through an appropriate set top box whilst the Internet variant can be accessed via Internet websites such as Channel 4 or SeeSaw.
As of April 2009, the Internet version is fully available to Windows, Mac and Linux users so long as Adobe Flash Player is installed. The "Catch-up" service offers content free of charge for both streaming and downloaded versions of a programme for thirty days after its broadcast on Channel 4. At this time, not all content is available to Irish users, due to licensing restrictions, however the majority of the programming is available.
A Download to Own (DTO) or "Buy" feature was once available on selected content, allowing users to purchase a programme and keep it for as long as they wish. This service has now been suspended alongside the application to power it, in favour of further investment into their online cross platform catchup service powered by Adobe Flash 10.
The 4OD service is also partly available on YouTube, launching in the United Kingdom in late 2009 with seven genre dedicated channels for 4OD, additional to separate channels Channel 4 and E4.


Teletext
4-Tel/FourText
Channel 4 originally licensed an ancillary teletext service to provide schedules, programme information and features. The original service was called 4-Tel and was provided in collaboration with Oracle. In 1993, with Oracle losing its franchise to Teletext Ltd, the running of 4-Tel was taken over by Intelfax, and in 2002 was renamed FourText.

Teletext on 4

In 2003, Channel 4 awarded Teletext Ltd a ten year contract to run the channel's ancillary teletext service, named Teletext on 4. The service is provided on both Channel 4 analogue and digital television services, Channel 4, E4 and More4. This has now been ceased and Teletext is no longer available on Channel 4, ITV and Five.

Operating profits for the year to 31 December 2006 fell 70% to £14.5 million from £56.9 million in 2005.

Headquarters


The Channel 4 building


The Channel 4 building with the Channel 4 Logo Statue outside
Channel 4 was originally based at 60 Charlotte Street in the West End of London. Since 1994 the channel has occupied distinctive, purpose-built headquarters at 124 Horseferry Road, Westminster. Designed by Richard Rogers Partnership with structural engineering by Ove Arup & Partners, its 15,000sq metres architecture follows on from - but is more restrained than - the Lloyd's building in the City of London, and was constructed between 1990 and 1994. Twin four-storey office blocks arranged in an L shape are connected by a curved front with a dramatic concave glazed wall.
Despite nearly all Channel 4 programmes being commissioned from independent production companies, the Channel 4 headquarters originally contained a studio and post-production facility, marketed as 124 Facilities. The studio was used for Channel 4 programmes (such as T4 continuity), and other channels' programmes such as Five's football coverage. The studio was closed at the end of October 2007 and only the post-production operation remains, though it is now managed by Red Bee Media.


Regions

Channel 4 has, since its inception, broadcast identical programmes and continuity throughout the United Kingdom (excluding Wales where it does not operate on analogue transmitters). At launch this made it unique, as both the BBC and ITV had long established traditions of providing regional variations in their programming and announcements between transmitters in different areas of the country (although in the case of BBC2, variations have by and large tended to be limited to national idents as opposed to regional ones). In ITV's case, this was a consequence of its inherent federal structure (see ITV companies). Since the launch of subsequent British television channels, Channel 4 has become typical in its lack of variations of this nature.
A few exceptions exist to this rule for programming and continuity: Ireland has a dedicated variant broadcast on Sky Ireland which omits programmes for which broadcast rights are not held in Ireland. For example, the series Glee is not available on Channel 4 on Sky in Ireland.
Some of Channel 4's schools' programming (1980s/early '90s) were regionalised due to differences in curricula between different regions.
Part of Channel 4's remit covers the commissioning of programmes from outside London. Channel 4 has a dedicated director of nations and regions, Stuart Cosgrove, who is based in a regional office in Glasgow. As his job title suggests, it is his responsibility to foster relations with independent producers based in areas of the United Kingdom (including Wales) outside of London.
Advertising on Channel 4 does contain regular variation: prior to 1993, when ITV was responsible for selling Channel 4's advertising, each regional ITV company would provide the content of advertising breaks, covering the same transmitter area as themselves, and these breaks were often unique to that area. After Channel 4 became responsible for its own advertising, it continued to offer advertisers the ability to target particular audiences and divided its coverage area into six parts coining the term 'LEMNUS' standing for "London, The East [and South] of England, The Midlands, The North of England, Ulster and Scotland. At present, Wales does not have its own advertising region, instead its viewers receive the southern region on digital platforms intentionally broadcast to the area, or the neighbouring region where analogue transmissions spill over into Wales. Ireland shares its advertising region with Northern Ireland (referred to by Channel 4 as the 'Ulster Macro') with many advertisers selling products for Ireland here. E4 also has an advertising variant for Ireland.
The six regions are also carried on satellite, cable and Digital Terrestrial. Five and GMTV use a similar model to Channel 4 for providing their own advertising regions, despite also having a single national output of programming.

Future possibility of regional news
With ITV plc pushing for much looser requirements on the amount of regional news and other programming it is obliged to broadcast in its ITV regions, the idea of Channel 4 taking on a regional news commitment has been considered, with the corporation in talks with Ofcom and ITV over the matter. Channel 4 believe that a scaling-back of such operations on ITV's part would be detrimental to Channel 4's national news operation, which shares much of its resources with ITV through their shared news contractor ITN. At the same time, Channel 4 also believe that such an additional public service commitment would bode well in on-going negotiations with Ofcom in securing additional funding for its other public service commitments.
