Channel 4

Channel 4 is a public-service British television station, broadcast to all areas of the United Kingdom (and also the Republic of Ireland), which began transmissions in 1982. Though entirely 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 for this purpose and which came into operation in 1993, following the abolition of the IBA.
