BBC Television is the television service of the BBC. The corporation has operated a public broadcast television service in the United Kingdom, under the terms of a royal charter, since 1 January 1927. It produced television programmes from its own studios from 1932, although the start of its regular service of television broadcasts is dated to 2 November 1936.
The BBC's domestic television channels have no commercial advertising and collectively they accounted for more than 30% of all UK viewing in 2013. The services are funded by a television licence.
As a result of the 2016 Licence Fee settlement, the BBC Television division was split, with in-house television production being separated into a new division called BBC Studios and the remaining parts of television (channels and genre commissioning, BBC Sport and BBC iPlayer) being renamed BBC Content.
The BBC operates several television networks, television stations (although there is generally very little distinction between the two terms in the UK), and related programming services in the United Kingdom. As well as being a broadcaster, the corporation also produces a large number of its own outsourcing programmes and thereby ranks as one of the world's largest television production companies.
John Logie Baird set up the Baird Television Development Company in 1926; on 30 September 1929, he made the first experimental television broadcast for the BBC from its studio in Long Acre in the Covent Garden area of London via the BBC's London radio transmitter propagating an analog signal. Baird used his electromechanical system with a vertically scanned image of 30 lines, which is just enough resolution for a close-up of one person, and a bandwidth low enough to use existing radio transmitters. The simultaneous transmission of sound and pictures was achieved on 30 March 1930, by using the BBC's new twin transmitter at Brookmans Park. By late 1930, thirty minutes of morning programmes were broadcast from Monday to Friday, and thirty minutes at midnight on Tuesdays and Fridays after BBC radio went off the air. Baird's broadcasts via the BBC continued until June 1932.
The BBC began its own regular television programming from the basement of Broadcasting House, London, on 22 August 1932. The studio moved to larger quarters in 16 Portland Place, London, in February 1934, and continued broadcasting the 30-line images, carried by telephone line to the medium wave transmitter at Brookmans Park, until 11 September 1935, by which time advances in the all-electronic 405-line television system made electromechanical broadcasts and systems obsolete.
Following a series of test transmissions and special broadcasts that began in August 1936, the BBC Television Service officially launched at 3.00pm on 2 November 1936 from a converted wing of Alexandra Palace in London. The opening day's programming started using the Baird System at 10.00 am with "Opening of the B.B.C. television service by Major G. C. Tryon", the Postmaster General of the United Kingdom, followed by the latest British Movietone News newsreel at 10.30. This was then followed up with a 10-minute variety show with Adele Dixon and the African-American duo of Buck and Bubbles, and the BBC Television Orchestra. These programmes were then shown at 3.00pm using the Marconi-E.M.I. System. "Ally Pally" housed two studios; Studio A for the 405-line Marconi E.M.I. system, and Studio B for Baird's 240-line intermediate film system. It also housed several scenery stores, make-up areas, dressing rooms, offices, and the transmitter itself, which then broadcast on the VHF band. BBC television initially used both the Baird and Marconi-E.M.I systems on alternate weeks. The use of both formats made the BBC's service the world's first regular high-definition television service; it broadcast from Monday to Saturday between 10:00 and 15:00, and 17:00 and 22:00. The first programme broadcast – and thus the first ever, on a dedicated TV channel – was "Opening of the BBC Television Service" at 10:00. The first major outside broadcast was the coronation of George VI and Elizabeth in May 1937.
The two systems were to run on a trial basis for six months; early television sets supported both resolutions. However, the Baird system, which used a mechanical camera for filmed programming and Farnsworth image dissector cameras for live programming, proved too cumbersome and visually inferior, and ended with closedown (at 22:00) on Saturday 30 January 1937. It was advertised in Radio Times for two weeks later but the decision to end the Baird system was made too late for it be changed in the printed Radio Times.
Initially, the station's range was officially a 40 kilometres radius of the Alexandra Palace transmitter—in practice, however, transmissions could be picked up a good deal further away, and on one occasion in 1938 were picked up by engineers at RCA in New York, who were experimenting with a British television set. The service was reaching an estimated 25,000–40,000 homes before the outbreak of World War II which caused the BBC Television service to be suspended on 1 September 1939 with little warning.
On 1 September 1939, the station went off the air; the government was concerned that the VHF transmissions would act as a beacon to enemy aircraft homing in on London. Also, many of the television service's technical staff and engineers would be needed for the war effort, in particular on the radar programme. The last programme transmitted was a Mickey Mouse cartoon, Mickey's Gala Premier (1933), which was followed by test transmissions; this account refuted the popular memory according to which broadcasting was suspended before the end of the cartoon.
According to figures from Britain's Radio Manufacturers Association, 18,999 television sets had been manufactured from 1936 to September 1939, when production was halted by the war.
The remaining monopoly years (1946–1955)
BBC Television returned on 7 June 1946 at 10:00. Jasmine Bligh, one of the original announcers, made the first announcement, saying, 'Good afternoon, everybody. How are you? Do you remember me, Jasmine Bligh? Well, here we are after a lapse of nearly seven years ready to start again and of course we are all terribly excited and thrilled...' The Mickey Mouse cartoon of 1939 was repeated twenty minutes later. On 31 December the BBC broadcast First-year Flashbacks, a compilation of the year's highlights. An edited copy is now the oldest programme on the BBC's iPlayer streaming service.
Alexandra Palace was the home base of the channel until the early 1950s, when the majority of production moved into the newly acquired Lime Grove Studios. Postwar broadcast coverage was extended to Birmingham in 1949, with the opening of the Sutton Coldfield transmitting station on 17 December, and by the mid-1950s most of the country was covered, transmitting a 405-line interlaced video image on VHF.
When ITV was launched in 1955, the BBC Television Service (renamed "BBC tv" in 1960) showed popular programming, including comedies, drama, documentaries, game shows, and soap operas, covering a wide range of genres and regularly competed with ITV to become the channel with the highest ratings for that week. The channel also introduced the science fiction show Doctor Who on 23 November 1963 - at 17:16 - which went on to become one of Britain's most iconic and beloved television programmes.
BBC TV was split into BBC1 and BBC2 in 1964, with BBC2 having a remit to provide more niche programming. The channel was due to launch on 20 April 1964, but this was postponed after a fire at Battersea Power Station resulted in most of west London, including Television Centre, losing power. A videotape made on the opening night was rediscovered in 2003 by a BBC technician. The launch went ahead the following night, beginning with host Denis Tuohy sarcastically blowing out a candle. BBC2 was the first British channel to use UHF and 625-line pictures, giving higher definition than the existing VHF 405-line television system.
