Independent Broadcasting Authority in the context of "Channel Four Television Corporation"

Channel 4 is a British free-to-air public broadcast television channel owned and operated by Channel Four Television Corporation. It is publicly owned but, unlike the BBC, it receives no public funding and is funded entirely by its commercial activities, including advertising. 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 BBC1 and BBC2, 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 nationwide television channel. The network's headquarters are in London and Leeds, with creative hubs in Manchester, Glasgow and Bristol.

Independent Local Radio is the collective name given to commercial radio stations in the United Kingdom.

As a result of the buyouts and mergers permitted by the Broadcasting Act 1990, deregulation resulting from the Communications Act 2003 and further deregulation from the Media Act 2024, most commercial stations are now neither independent (although they remain independent from the BBC) nor local, as almost all of them are now relays of a national brand, with remaining locality reduced to nothing more than localised commercials, news (which may be from the Ofcom approved area region), weather and peak-time travel information.
