BBC Two (or BBC2 as it was formerly styled) was the second UK television station to be aired by the BBC and Europe's first television channel to broadcast regularly in colour (from 1967), envisaged as a home for less mainstream and more ambitious programming.
At 11 a.m. on April 21, power had been restored to the studios and programming began, thus making Play School the first official programme to be shown on the channel. The launch schedule, postponed from the night before, was then successfully shown that evening albeit with minor changes. In reference to the power cut, the transmission opened with a shot of a lit candle which was then sarcastically blown out by presenter Denis Tuohy.
To establish the new channel's identity and draw viewers to it, the BBC decided that a widely promoted, lavish series would be essential in its earliest days. The production chosen was The Forsyte Saga, a no-expense-spared adaptation of the novels by John Galsworthy, featuring well-established actors Kenneth More and Eric Porter. Critically for the future of the fledgling channel, the BBC's gamble was hugely successful, with an average of six million viewers tuning in per episode of a total of only 9 million able to receive the channel at the time, and BBC 2 was safely established with the public.
Unlike the other channels available at that time (BBC One and ITV), BBC Two was broadcast only on the 625 line UHF system, so was not available to viewers with 405 line VHF sets. This created a market for dual standard receivers which could switch between the two systems. BBC One and ITV later joined BBC Two on 625-line UHF but continued to simulcast on 405-line VHF until 1985. BBC Two became the first channel in Europe to broadcast in colour in July 1967, using the PAL system. BBC One and ITV simultaneously introduced PAL colour on UHF in late 1969. BBC Two is to be the first BBC channel to leave the domain of analogue television. The analogue service will be switched off from 2008, region by region, about a month before the other remaining analogue channels. This will be the first major step in forcing those relying on analogue signal over to one of the BBC's digital platforms - Freeview or Freesat.
The channel has often been judged in more recent years to have moved away from this original role and become increasingly oriented towards the mainstream. The perception of its greater minority interest nevertheless persists in today's multi-channel world so that a programme that is moved from BBC Two to BBC One will often attract a much larger audience, even though no other change has been made. Since 2004 there have been some signs of an attempt to return closer to parts of BBC Two's earlier output with the new arts strand The Culture Show and intermittent night-time repeats of programming from BBC Four.
During the evenings BBC Northern Ireland broadcast local programmes on BBC Two NI, while BBC Wales broadcasts a special channel BBC 2W. These are both only available on Digital Television such as Freeview; presently, during this period BBC Two's regular programming is only available via analogue transmission. Additionally, BBC Two Scotland broadcasts Gaelic-language programmes, often under the banner "BBC Two Alba". BBC Wales also broadcast BBC Two Wales which is simular to network BBC Two but with local continuity and occasional opt-outs on their analogue transmitters.
Following a long and important association with the Open University, which has always co-produced programming with the channel, BBC Two has also carried BBC's Schools programmes from 1983 onward from BBC One. In recent years the Open University programming has been broadcast under the wider category of BBC Learning Zone, in its longstanding slot late at night and during the early hours. However, in 2004 the Open University announced it is to stop its late night programmes on BBC Learning Zone in 2006.
As a result of the channel's commitment to community broadcasting and amongst other related programming the channel produced the symbolic "Open Space" series, a strand developed in the early 1970s in which members of the public would be allotted half an hour of television time, and given a level of editorial and technical training in order to produce for themselves a film on an issue most important to them. BBC Two's Community Programmes Unit kept this aspect of the channel's tradition alive into the 1990s in the form of Video Diaries and later Video Nation, an intended role which, despite intermittent reappearances in the form of "Video Shorts" has since gradually been given up during the channel's move toward the mainstream.
As well as programmes, BBC Two has also proved memorable for its numerous idents—various short films shown in between programme junctions, promoting the channel identity. Since it began in 1964, the figure '2' has almost always been used, using revolving, mechanical models and computer-aided technology, including the world's first computer-generated ident in 1979. On Easter 1986 the '2' was replaced by the word 'TWO' in red, green and blue on a white background. However, a survey carried out by the BBC in 1990 found that this gave the channel a 'dull' and 'old-fashioned' image, and the ident was changed back to a figure '2' in 1991. From then the '2' appeared the same shape but in various guises, adopting ideas like a remote-controlled car, a rubber duck, a dalek and a fluffy dog. These are generally regarded as the best idents ever produced for a television channel and stayed in use for 10 years, ending in November 2001, (but the new BBC Logo was incorporated within the idents from 1997 to 2001). From November 19th 2001, the figure '2' remained, but it was now always shown white on a yellow background, with various computer technology to aid it. Occasionally, the ident changes also to advertise a show on BBC Two. For example, as a trailer for the second series of The Catherine Tate Show, one of the characters is shown arguing with a '2', in the guise of a dog.
In some rare cases, withdrawn idents have been brought back for special events. The 'Garden' ident (where a 2 grows out of flowers) was re-used for the 2001 Chelsea Flower Show, after having been retired in 1997, and remained in occasional use until the November 2001 refresh. For the 2006 Winter Olympics, the 2000 Christmas ident was used again. For the 2006 Chelsea Flower Show, the 'Predator' ident (The one where the 2 butterfly gets eaten by the Venus 2-trap) was used again. In each case, the branding has been updated to match the current style.
On July 2, 2006, it was confirmed that new idents will be produced for the channel, recent reports have gone around that the channel flagship identity since 1991 the '2' is to be dropped after 15 years.
