BBC Two

BBC Two is the second flagship television channel of the British Broadcasting Corporation in the United Kingdom, Isle of Man and Channel Islands. It covers a wide range of subject matter, but tends to broadcast more "highbrow" programmes than the more mainstream and popular BBC One. Like the BBC's other domestic TV and radio channels, it is funded by the television licence, and is therefore free of commercial advertising. It is a comparatively well-funded public-service network, regularly attaining a much higher audience share than most public-service networks worldwide.

Originally styled BBC2, it was the third British television station to be launched (starting on 21 April 1964), and from 1 July 1967, Europe's first television channel to broadcast regularly in colour. It was envisaged as a home for less mainstream and more ambitious programming, and while this tendency has continued to date, most special-interest programmes of a kind previously broadcast on BBC Two, for example the BBC Proms, now tend to appear on BBC Four instead.

Launch
British television at the time of BBC2's launch consisted of two channels: the BBC Television Service and the ITV network made up of smaller regional companies. Both channels had existed in a state of competition since ITV's launch in 1955, and both had aimed for a populist approach in response. The 1962 Pilkington Report on the future of broadcasting noticed this, and that ITV lacked any serious programming. It therefore decided that Britain's third television station should be awarded to the BBC.

Prior to its launch, the new BBC2 was promoted on the BBC Television Service: the soon to be renamed BBC1. The animated adverts featured the campaign mascots "Hullabaloo", a mother kangaroo, and "Custard", her joey. Prior to, and several years after, the channel's formal launch, the channel broadcast "Trade Test Transmissions", short films made externally by companies such as Shell and BP, which served to enable engineers to test reception, but became cult viewing.

The channel was scheduled to begin at 19:20 on 20 April 1964, showing an evening of light entertainment, starting with the comedy show The Alberts, a performance from Soviet comedian Arkady Raikin, and a production of Cole Porter's Kiss Me, Kate, culminating with a fireworks display. However, at around 18:45 a huge power failure, originating from a fire at Battersea Power Station, caused Television Centre, and indeed much of west London, to lose all power. BBC1 was able to continue broadcasting via its facilities at Alexandra Palace, but all attempts to show the scheduled programmes on the new channel failed. Associated-Rediffusion, the London weekday ITV franchise-holder, offered to transmit on the BBC's behalf, but their gesture was rejected. At 22:00 programming was officially postponed until the following morning. As the BBC's news centre at Alexandra Palace was unaffected, they did in fact broadcast brief bulletins on BBC2 that evening, beginning with an announcement by the newsreader Gerald Priestland at around 19:25. There was believed to be no recording made of this bulletin, but a videotape was discovered in early 2003.

By 11:00 on 21 April, power had been restored to the studios and programming began, thus making Play School the first programme to be shown officially 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 (1967), 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: a feat made more prominent by the fact that only 9 million were able to receive the channel at the time.

Technological advancements
Unlike BBC1 and ITV, BBC2 was broadcast only on the 625 line UHF system, so was not available to viewers still using sets on the 405-line VHF system. This created a market for dual standard receivers which could switch between the two systems. Set manufacturers ramped up production of UHF sets in anticipation of a large market demand for the new BBC2, but the market did not materialise. The early technical problems, which included being unable to transmit US-recorded videotapes due to a lack of system conversion from the US NTSC system, were resolved by a committee headed by James Redmond.

On 1 July 1967, during the Wimbledon Championships, BBC2 became the first channel in Europe to begin regular broadcasts in colour, using the PAL system. The thirteen part series Civilisation (1969) was created as a celebration of two millennia of western art and culture to showpiece the new colour technology. BBC1 and ITV later joined BBC2 on 625-line UHF band, but continued to simulcast on 405-line VHF until 1985. BBC1 and ITV simultaneously introduced PAL colour on UHF on 15 November 1969, although they both had broadcast some programmes in colour "unofficially" since September 1969.

In 1979, the station adopted the first computer-generated channel identification (ident) in Britain, with its use of the double striped, orange '2' logo. The ident, created in house by BBC engineers, lasted until March 1986 and heralded the start of computer-generated logos.

As the switch to digital-only terrestrial transmission progressed, BBC Two was (in each region in turn) the first analogue TV channel to be replaced with the BBC multiplex, at first four, then two weeks ahead of the other four channels. This was required for those relay transmitters that had no current Freeview service giving viewers time to purchase the equipment, unless they had already selected a satellite or cable service. The last region for BBC Two to end on analogue terrestrial television was Northern Ireland on 10 October 2012.

At the 2012 Edinburgh International Television Festival, BBC Two was named "Terrestrial Channel of the Year".

A high-definition simulcast of BBC Two began broadcasting on 26 March 2013, replacing the standalone BBC HD channel. , there are 3 variations of BBC Two HD (Wales, Northern Ireland, and England).

Presentation
As well as programmes, BBC Two has also proved memorable for its numerous idents—various short sequences shown between programme junctions that serve as the channel identity. Nearly all of the identity packages used since the channel's launch in 1964 have featured a prominent numeral 2 in the design. Notable designs include the electronic double-striped 2, the white TWO ident (the only ident not to use a numeral 2), and most notably the 1991 2s.

The 1991 idents featured a sans-serif numeral 2 at the centre of an initially art-related scene; however the idents moved away from this style as the station's style changed. Although highly praised, this expansive set of idents was ended in November 2001. The BBC corporate logo was updated within the idents in October 1997, though the idents moved away from the original viridian colour scheme in these latter years. The subsequent presentation style was introduced on 19 November 2001 and kept the same figure 2, but in a yellow background and given a personality. At the time, BBC Two became the first BBC channel to feature a box logo.

In 2007, BBC Two debuted the new theme, a "Window on the World", with the 2 numeral providing that view. Introduced on 18 February 2007, the new look also had the channel adopt a teal-coloured box logo, featuring the BBC logo above the word TWO, in the font Avenir.

In 2014, in honour of the channel's 50th anniversary, some of the 1990s idents were re-introduced; from 2015, BBC Two Northern Ireland opted to use nearly forty idents from the 1991–2001 set.

On 27 September 2018, the 1991-2001 idents were retired once again and BBC Two introduced a new set of idents, based on scenes incorporating a curve motif resembling the number 2. The new branding is designed to reflect BBC Two's "constant evolution, constant eclecticism, [and] constant sense of quality". The new idents are produced by various artists and studios, including Aardman Animations, The Mill and others. The new identity was co-developed by BBC Creative and Superunion.

Regional variations
BBC Two also has regional variations in Wales and Northern Ireland. These versions of BBC Two share the same idents, but with the nation name in the BBC Two box. BBC Two Scotland showed a lot of specifically Scottish programming on the channel, as well as its sister channel BBC One Scotland, and the schedules were often mixed around to match. BBC Two Northern Ireland and BBC Two Wales both have the option to opt out of the main network schedule, but generally stick to it, only opting out a couple of times each week. Until December 2008, BBC Wales broadcast a special, digital-only channel, BBC 2W, which contained more opt-outs than analogue-only BBC Two Wales. BBC Two Scotland existed until February 2019 when it was replaced with the national BBC Two feed in preparation for the launch of the BBC Scotland channel.

In England, many of the BBC English regions were combined to form "super-regions", such as the entire North or Midlands. These had the option to opt out of the network programming on the analogue feed, and replace it with local programming. However this was usually only done in exceptional circumstances, as all regular regional programming has been transferred to BBC One, and the English regions are not available on digital on BBC Two. There is no specific "BBC Two England"; this role is fulfilled by the network version of BBC Two.
