Timeline of overnight broadcasting in the UK
This is a timeline of overnight television broadcasting in the United Kingdom. It focuses on programming between midnight and 6am and includes details of when channels began into the night and 24-hour broadcasting. 1980s
1983
LWT becomes the first station in the UK to begin broadcasting into the night when it launches Nightlife, resulting in LWT staying on air until around 2am on Friday and Saturday nights. 1984
4–12 August – During the second week of the 1984 Summer Olympic Games, the BBC extends its live coverage until around 4am. Rather than closing down, the BBC fills the gap with Ceefax Olympics AM which provides news from the Games to fill the gap between the end of live coverage and the start of Olympic Breakfast Time. 1985
 No events. 1986
2 April – Central launches a Jobfinder service which airs for one hour after the end of the day's programming. It becomes the first in-vision teletext service to be seen on ITV. 9 August – Yorkshire launches an experimental overnight service, simulcasting the satellite TV channel Music Box. YTV carries Music Box until 6am when there is a brief break in transmission as in 1986, TV-am wasn't starting its broadcast day until 6.15 (weekdays) and 6.55 (weekends). 1987
3 January – Closedowns reappear on Yorkshire when its experiment with 24-hour television is put on hiatus. 13 January – Yorkshire becomes the second ITV region to launch a Jobfinder service which also airs for an hour after closedown. 23 April 
Channel 4 starts broadcasting into the early hours on Thursdays, Fridays and Saturdays when it launches Nightime. One of the programmes is the discussion show After Dark which was broadcast live and with no scheduled end time. Yorkshire extends broadcasting into the early hours on Thursday, Friday and Saturday nights by introducing a Through Till Three strand. 25 April – Central becomes the first station to keep its transmitters on air all night on a permanent basis when it launches More Central. Programmes are shown until around 3am on weekdays and 4am at the weekend, with the rest of the night filled by its Jobfinder service. 1 June – Thames launches Thames Into the Night, broadcasting until around 4am. This programme extension co-insides with the cessation of Thames's end of day epilogue Night Thoughts. 17 August – Thames becomes the first ITV company to launch a full 24-hour service. 28 August 
LWT and Anglia begin 24-hour transmissions. LWT launches the UK's first overnight show Night Network. 7 December – Tyne Tees begins 24-hour broadcasting. It does so by launching a Jobfinder service which airs each night from its usual closedown time until the start of TV-am at 6am. 1988
25 January – TVS launches Late Night Late and gradually extends its broadcast hours over the next few months. 15 February 
Channel 4 starts broadcasting into the early hours every night, closing down between 2am and 3am. Previously, Channel 4 had closed down on Sundays to Wednesdays at between midnight and 1am. An early morning 60-minute news programme, ITN Early Morning News, is launched but is only available in areas which have 24-hour broadcasting. The first 30 minutes includes a full broadcast of ITN's international news bulletin ITN World News. In addition, brief news summaries are broadcast at various points through the night. The launch coincides with three of the major ITV companies, Scottish, Central and Granada, beginning 24-hour transmissions. 30 May – Yorkshire recommences 24-hour broadcasting. 20 June – TVS and Channel begin 24-hour broadcasting. 22 August – HTV begins 24-hour broadcasting. The service, called Night Club, is broadcast on both HTV West and HTV Wales. 2 September 
TSW, Grampian and Border begin 24-hour broadcasting. Granada launches an overnight service called Night Time to make it easier for the smaller companies to introduce 24-hour broadcasting. TSW, Border and Grampian take the service, as does Tyne Tees which replaces its all-night showing of Jobfinder with the new service. Jobfinder is part of Night Time and airs as a regional service between 4am and 5am on weeknights. 17 September–2 October – Channel 4 broadcasts all night for the first time to provide full live coverage of the 1988 Olympic Games. BBC1 also provides all night Games coverage and consequently broadcasts non-stop for 16 days. 3 October – Ulster begins 24 hour broadcasting. Ulster had planned to commence 24-hour transmissions a month earlier but it was delayed because of a last minute decision to take the overnight service provided by Granada and not that provided by Central. Autumn – The BBC takes its first tentative steps into later closedowns. Previously, weekday programmes ended no later than 12:15am and weekend broadcasting had finished by 1:30am. 1989
6 February – Sky Television launches. Sky News broadcasts a 24-hour service from day one and for a while, Sky Channel airs teletext pages during its overnight downtime. 31 March – Night Network ends after a little more than 18 months on the air. 1990s

None of its five channels broadcast around the clock but, apart from Now, the channels do broadcast into the early hours. A test card is shown during the channels' downtime. 1991
late January – The BBC and ITV broadcast extensive live coverage of the Gulf War, both in terms of extended news bulletins and special programmes. All-night coverage is aired on both channels during the early stages of the war. ITV broadcasts an all-night news programme and BBC1 airs Pages from Ceefax to keep viewers up to date. This overnight coverage had ended by the start of February. 3 March – Following the conclusion of the Gulf War, the ITN Early Morning News is halved in length and now goes on the air at 5:30am. From this point, the ITN World News is no longer broadcast as part of the bulletin. April – LWT and Thames launch a new overnight strand called ITV Night Time. 28 April – HTV closes down its Night Club and replaces it with a simulcast of the overnight generic ITV service from London. 6 May — Sky Movies and The Movie Channel begin broadcasting 24 hours a day. Previously they had been on air from early afternoon until the early hours of the next morning. August – TVS stops airing their own overnight strand Late Night Late and is replaced by a new ITV Night Time service from London, provided by Thames from Monday to Thursday and LWT from Friday to Sunday. For the first time, both London companies utilised the same on-screen branding throughout the week, the only notable difference being LWT's near non-use of a continuity announcer at the weekend. 1 September – Anglia's Through the Night service ends. It is replaced by the generic overnight service from London which is also broadcast on HTV. October – Scottish rebrands its overnight service as Scottish Night Time and removes the overnight in-vision continuity. 1992
21 January – BBC Select is launched as an overnight subscription service. 5 October – Following the merger of Yorkshire and Tyne Tees, the two ITV companies begin broadcasting the same overnight service called Nightshift. 1993
1 January 
Granada’s overnight service begins broadcasting on Anglia, HTV Wales, HTV West (from 1 January 1993) and on Westcountry which had replaced TSW as ITV’s South West of England contractor. The new ITV franchise holder for London weekdays, Carlton introduced a new Nightime service, airing from Monday–Thursday nights and simulcast by Meridian and Channel Television. 3 January – 3 Nights is launched by LWT as its overnight service. Output includes some of LWT’s local programmes. January – On Friday, Saturday and Sunday nights, Meridian and Channel broadcast its own version of Nighttime, presented in-vision from Southampton by ex-Late Night Late presenter Graham Rogers. Both Carlton and Meridian/Channel services utilised the same on-screen branding and presentation throughout the week. Programming largely consists of output airing on the other services as well as imports including French soap Riviera and in the case of Meridian, regional programming, including World Of Sailing and Freescreen, an experimental series featuring viewers' videos and social action features. 19 January – Schools programmes are shown overnight on BBC2 for the first time as part of a new experiment called Night School. The broadcasts are generally either subject blocks or series blocks. Instead of fully closing down, 4-Tel on View is shown throughout Channel 4’s overnight downtime. The teletext pages are accompanied by a continuous tone with music only being played in the final 30-or-so minutes prior to the start of the next day’s programmes. 1994
19 June – More Central which had been the brand name for Central’s overnight broadcasting since it began nighttime transmissions in 1987 ends. Yorkshire and Tyne Tees resume local overnight continuity. After two years of sharing transmissions, the schedule and the overnight brand name of Nightshift is retained by both regions. 1995
 9 January – Sky One begins 24-hour broadcasting, filling the overnight hours with music videos under the name Hit Mix Long Play. February – Central ends its own nighttime programming and carries the London overnight service, although opt-outs for Jobfinder and other regional programming continues. 13 February –  London News Network (a subsidiary of Carlton & LWT) launches a revamped overnight service featuring new neon-themed presentation without any station-specific branding. Following the launch of the LNN service over much of the ITV network, Meridian's overnight service expanded to seven days a week and began airing in the Anglia region. Overnight continuity links were dropped in favour of announcer-less idents and presentation. 5 June – Granada closes its Night Time service and replaces it with the new national overnight service from London. Consequently, Border, Grampian, UTV, HTV Wales (5 June–31 December 1995), HTV West and Westcountry all take the London service. 9 October – BBC Learning Zone is launched, broadcasting education programmes all night Sundays to Thursdays on BBC2. BBC2 continued to close down on Friday and Saturday nights and during the Christmas period when the Learning Zone is not on. It replaces BBC Select and Night School. 16 October – Following the launch of the BBC Learning Zone, Pages from Ceefax is broadcast in the gaps between the end of regular programmes and the start of Learning Zone broadcasts. This is the first time that Ceefax is broadcast overnight on a regular basis. 1996
January – Meridian's programming is adopted by HTV and Westcountry, albeit with separate local presentation from HTV's presentation centre in Cardiff.

14 January – ITV Nightscreen launches as an overnight filler on ITV. Broadcast as teletext pages, the service features news and information about ITV and its programmes. Early in 1998, BBC2 stops shutting down its transmitters when it isn’t broadcasting the BBC Learning Zone. Instead, BBC2 airs Pages from Ceefax during all overnight downtime. 26 January – ITV Night Time launches on Tyne Tees and Yorkshire, bringing to an end to their Nightshift after nearly six years. 2 November – The SMG relaunches its own overnight programming for its two regions, Scottish and Grampian. The overnight strand is called Nighttime TV. Meridian drops The Edge and replaces it with a set of idents using generic ITV branding. These idents were amended later that year to reflect the change of ITV's generic logo and continued to be used until May 2000, by which time, Meridian had adopted the generic overnight branding used by the rest of the network since November 1999. 1999
9 November – ITV Night Time is rolled out to many more ITV regions, including Granada, Border, Central, Tyne Tees, UTV and Yorkshire. At this time, ITV phases out the Night Time logos and presentation on overnight shows by late 1999 with generic network branding taking its place in most regions and ITV Nightscreen starting to take up timeslots towards the end of the night although Central and Yorkshire partially opt out of Nightscreen to show Jobfinder. BBC One starts showing recent programmes with in-vision signing in a slot called Sign Zone. Programmes are broadcast for the first half of the night with BBC News 24 continuing to air for the remainder of the night. 2000s
