{{See also|Television in the United Kingdom}}
The first television network in the United Kingdom was operated by the British Broadcasting Corporation ([[BBC]]). On 2 November 1936 the BBC opened the world's first regular high-definition television service, from a 405 lines transmitter at Alexandra Palace. The BBC remained dominant until eventually on 22 September 1955, commercial broadcasting was established to create a second television network. Rather than creating a single network with local channels owned and operated by a single company (as is the case with the BBC), each local area had a separate television channel that was independently owned and operated, although most of these channels shared a number of programmes, particularly during peak evening viewing hours. These channels formed the [[ITV (TV network)|ITV network]].

When the advent of [[Ultra high frequency|UHF]] broadcasting allowed a greater number of television channels to broadcast, the BBC launched a second channel, [[BBC Two|BBC 2]] (with the original service being renamed [[BBC One|BBC 1]]). A second national commercial network was launched [[Channel 4]], although [[Wales]] instead introduced a Welsh-language service, [[S4C]]. These were later followed by the launch of a third commercial network, [[Channel 5 (UK)|Channel 5]]. Since the introduction of digital television, the BBC, ITV, Channel 4 and Channel 5 each introduced a number of digital-only channels. [[Sky Limited|Sky]] operates a large number of channels, as does [[UKTV]].
