1990s

1996

• 9 May – The BBC announces its plans for digital television. They include a free-to-air news channel, widescreen versions of BBC1 and BBC2, "side channels" which will broadcast extra programmes related to what is on the main channels and a series of paid-for channels featuring programming from the BBC archives.^[1]
• The BBC holds talks with Flextech^[2] and BSkyB^[3] about a partnership to launch the paid-for channels. The BBC later decides not to pursue any partnership with BSkyB.

1997

• 4 March – The BBC and Flextech agree on a deal to provide several BBC-branded channels – BBC Showcase, for entertainment; BBC Horizon, for documentaries; BBC Style, for lifestyle; BBC Learning, for schools, and BBC Arena, for the arts – plus three other channels: BBC Catch-Up, for repeats of popular programmes within days of their original transmission, a dedicated BBC Sport channel and a TV version of Radio 1.^[4]
• 9 October – The Department of Culture, Media and Sport gives the BBC permission to offer its forthcoming 24-hour news channel free to cable operators, thus breaking a monopoly that had previously been held by Sky News.^[5]
• 1 November – Three of the proposed BBC/Flextech channels, UK Horizons, UK Style and UK Arena launch, but they use the ‘UK’ prefix because Flextech wanted these channels to carry adverts but the BBC did not. BBC Showcase/Catch-Up and BBC Learning are removed from the venture and launched in 1998 and 1999 as BBC Choice and BBC Knowledge respectively. The proposed TV version of Radio 1 eventually launches as a music and comedy channel called UK Play but with no connection to Radio 1 and plans for the sports channel come to nothing.
• 9 November – At 6pm, BBC News 24 is launched. It is the BBC's first new UK channel since BBC Two in 1964. It is only available full time via cable with all other viewers able to see the channel overnight on BBC One.

1998

• 10 June – The BBC switches on its digital signal, doing so to coincide with the start of the 1998 FIFA World Cup. The technology will be showcased at a number of public venues over the Summer, before the launch of the BBC's first digital television channel, BBC Choice, in the Autumn.^[6]
• 23 September
  • BBC Choice, the UK's first digital-only TV station, launches at 12pm.^[7] However, viewers can only watch the launch online due to digital receivers not being on sale to the general public yet.
  • Following its purchase of the cable-only Parliamentary Channel, the BBC launches BBC Parliament on digital satellite and analogue cable with an audio feed of the channel on DAB.^[8]
• 15 November – The public launch of digital terrestrial TV in the UK takes place. Consequently, BBC Choice is now viewable by the general public via their television sets which have digital equipment.

1999

• 1 June – The educational channel BBC Knowledge launches at 5pm.^[9]
• 29 September – The European Commission rejects a complaint from BSkyB that the licence fee funding of BBC News 24 is illegal under EU law because it amounts to state funding.^[10]
• 25 October – Relaunch of BBC News 24 with a new set design.^[11]
• 29 November – From that day, children's programming is broadcast all day on BBC Choice. Branded CBBC on Choice, children's programming is broadcast on the channel every day from 6am until 7pm.

2000s

2000

• June – BBC Choice and BBC Knowledge are reformatted to focus on more specific audiences. Knowledge adopts a broader documentary and culture mix and Choice focusing on developing a stronger relationship with the young adult audience, an audience the BBC had historically had difficulty in reaching. Many of its original programmes, such as Backstage, were replaced with shows aimed at younger people, with most of the early part of the schedules being made up of fifteen-minute programmes under the banner of "Refreshing TV" or "Micro TV". Entertainment news magazine Liquid News, presented by Christopher Price, evolved out of News 24's Zero 30 and became the channel's flagship show.
• 6 August – It is reported that the BBC is considering a reorganisation of their digital channels to replace BBC Choice and BBC Knowledge with BBC Three and BBC Four.^[12]

• 10 April – BBC Four airs Ian Curteis's The Falklands Play, in which Patricia Hodge plays the role of Margaret Thatcher during the Falklands War.^[16][17] The play was originally written in 1986, but shelved by the BBC because of an upcoming General Election and the play's perceived pro-Thatcher stance. The play has separate radio and television versions (airing on Radio 4 on 6 April), and gives BBC Four an audience of 174,000, the channel's highest audience since its launch.^[18]
• 3 June – BBC Parliament broadcasts archived programming for the first time when it reruns the BBC's coverage of the Queen's Coronation as part of the Golden Jubilee Weekend.

The first to be shown is the coverage of the results of the 1979 General Election and the following day, the channel shows the results programme of the 1997 General Election. These reruns have subsequently been a mainstay of the channel ever since and are usually shown to coincide with the anniversaries of their original transmissions.
• September – BBC Three is finally given the go-ahead after the BBC submitted a revised proposal for the new channel. It raised the target age range to 25–34 and increased the amount of factual, news and arts programming. It had previously been refused over worries that it would be too similar to rival channels such as E4, ITV2 and Sky 1.
• 6 October – BBC Choice's Liquid News is relaunched with a new studio and graphics and a new presenting team consisting of Claudia Winkleman and Colin Paterson.^[19][20]

Networked news on BBC One and Two remains with the same titles though the set was redesigned in a similar style to that of the new News 24.
