Channel 4 is a British free-to-air public broadcast television channel owned and operated by the state-owned Channel Four Television Corporation. It is publicly owned but, unlike the BBC, it receives no public funding and is instead funded entirely by its own commercial activities, including publicity. It began its transmission in 1982 and was established to provide a fourth television service in the United Kingdom. At the time, the only other channels were the licence-funded BBC One and BBC Two, and a single commercial broadcasting network ITV.
Originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by Channel Four Television Corporation, a public corporation of the Department for Culture, Media and Sport, which was established in 1990 and came into operation in 1993. Until 2010, Channel 4 did not broadcast in Wales, but many of its programmes were re-broadcast there by the Welsh fourth channel S4C. In 2010, Channel 4 extended service into Wales and became a UK-wide television channel. The network's headquarters are in London and Leeds, with creative hubs in Glasgow and Bristol.
Fourth UK television service
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; Channel 4 was formally created, along with its Welsh counterpart, by an act of Parliament in 1982. After some months of test broadcasts, it began scheduled transmissions on 2 November 1982 from Scala House, the former site of the Scala Theatre.
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 often had a spare tuning button labelled "ITV 2" or "IBA 2".

London ('lʌndən ) is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as Londinium and retains its medieval boundaries. The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament.
