List of Big Brother (British TV series) shows

This is a complete list of shows about and relating to Big Brother UK and Celebrity Big Brother. The civilian edition originally ran from 2000 to 2018, and again since 2023. The celebrity edition ran from 2001 to 2018, and again since 2024.

Big Brother is the daily show, featuring highlights of events that have occurred in the Big Brother House on the previous day. From 2000–2010, during the Channel 4 broadcast, it was generally 60 minutes in length if aired at 9 pm, and 75 minutes if aired at 10 pm. The show was sometimes referred to as the "Channel 4 show", the "catch-up show", the "main show", or the "highlights show". On Fridays it was aired as the first part of the eviction show. The programme was broadcast by Channel 5 from 2010-2018 and aired each night for 60 minutes. There was no title of Big Brother during the opening sequence or after advert breaks, as the music and Big Brother Eye were expected to be known to most people. When the show relaunched for a second time on ITV2 in 2023, the highlights show will be broadcast from Sunday to Friday, with no episode on a Saturday.

Big Brother Eviction is a programme where a housemate is evicted from the Big Brother House.

From 2000–2010, during the Channel 4 broadcast, it aired as a two-part show on Fridays from 9 pm, presented by Davina McCall. The first 60 minutes of the show were highlights of the previous day, shown in the same format as Big Brother.

The show returned at 10:35 pm for half an hour, when the Housemate with the largest percentage of the public vote was evicted and interviewed by McCall. At the end of the interview, the evictee is shown their "Time in the House", a compilation of their most memorable moments in the house. During Big Brother 10, two special guests such as celebrities and psychologists joined the evictee, giving their questions and views on how they fared in the House, however this was not carried through to any of the series that followed.

Eviction shows are often extended if something special is happening that night, such as new housemates, a double eviction, or a secret task. Timings were changed briefly in Big Brother 9 in order to achieve better ratings, however they soon reverted to normal.

Celebrity Big Brother 8 saw only one eviction show airing at 9:00 pm on Friday. The first 45 minutes of this show was highlights from the previous day in the House.

The final 15 minutes of the same show is when the Housemate with the smallest percentage of the public vote to save is evicted and interviewed by Dowling. At the end of the interview, the evictee is shown their "Time in the House", a compilation of their most memorable moments in the house.

Since the start of the regular 2011 series of Big Brother, there have been two eviction shows airing, in the same format of the Channel 4 eviction shows. During the first show, the highlights of the previous day in the House are shown. In the second show, the Housemate with the fewest votes to save is evicted and interviewed by Brian Dowling. This is pre-recorded around half-hour before broadcast.

Celebrity Big Brother 9 took the same eviction show format as the eighth celebrity series, apart from the final week where two episodes aired. The first show aired at 9 pm with the highlights and an eviction. The second aired at 11 pm and saw another eviction and interview.

Big Brother 13 started with Eviction shows in the same length as the Celebrity Big Brother 8 episodes for the first four evictions, with Live Feed airing for half an hour afterwards on 5*. However, Channel 5 reverted to the 9 pm and 11 pm schedule from Week 5 to 7, with the Highlights and Eviction announcement airing at 9 pm and the eviction and interview taking place during the 11 pm show.

During Big Brother 14, eviction shows took on a 90-minute format airing between 9 pm and 10:30 pm on Channel 5. This format was followed throughout the series. The eviction show was followed by Big Brother's Bit on the Side at 10:30 pm and Big Brother: Live from the House at 11:30 pm.

The first week of Big Brother 15 saw the original two show format (at 9 for highlights and 11 pm for the eviction of Tamara Stewart-Wood) but from the second week the one 90-minute show format was reinstated with the eviction taking place just after 10 pm.

Big Brother: Live Eviction takes place on Friday's at 9pm and runs for an hour and fifteen. The evicted housemate is not immediately interviewed upon leaving the house and instead has their first interview on the spin-off show Big Brother: Late & Live.^[1]

Celebrity Big Brother: Live Eviction takes place on Tuesday's and Fridays at 9pm and runs for an hour and fifteen. The evicted housemate is not immediately interviewed upon leaving the house and instead has their first interview on the spin-off show Celebrity Big Brother: Late & Live.

Big Brother's Bit on the Side^[2] was the daily news/magazine based show about Big Brother which was presented by Rylan Clark-Neal every night of the week. Emma Willis previously presented the show on non-eviction nights, however as of February 2015, Clark became the sole presenter.^[3] The show is filmed in Stage 6 at Elstree Studios, which is only a short walk from the main house itself.

During Big Brother 14, the Saturday show was renamed Big Brother's Bit on the Psych with a focus on psychological analysis of the housemates, and was presented by Clark with co-hosts Iain Lee and Luisa Zissman. The Sunday show was renamed Rylan's Supersized Celebrity Sunday during 2013 and focused on celebrity guests and entertainment. The Saturday and Sunday editions of Bit on the Side did not return for Celebrity Big Brother 15, meaning the show only aired 5 times a week. Prior to Big Brother 14, the show was presented by Emma Willis on week days, with Jamie East and Alice Levine on the weekend shows.^[4]

On 2 February 2015, it was announced that Emma Willis had decided to step down from her role on Bit on the Side in order to focus on presenting the main show and reduce her workload.^[3] The show's first episode aired on Channel 5 at 10:30 pm on 18 August, straight after the launch of the 2011 celebrity series^[5] with Alex Reid as the first panellist on the show.

The show features debates and conversations about the latest goings on in the house with a studio audience and celebrity panel. During Big Brother 2011, Saturday's edition of the show took the form of a chat show with celebrity guests and Sunday's edition of the show was a 'Sunday game show', based on the weeks action from the House, with Josie Gibson and Jamie East as the regular team captains. Each daily edition also contains a news feature covering the day's action in the Big Brother House. The show also contains a round up of online activity which was hosted by a member of the digital team until January 2015. It is now incorporated into the main show and hosted by the presenter on that evening.

On 17 April 2013, it was announced that Alice Levine and Jamie East would be departing the show. On 14 May, Channel 5 confirmed that Rylan Clark and AJ Odudu will present the show, alongside Willis from Tuesdays to Thursdays and post eviction each week. Clark would also present a Sunday lunchtime edition of the show.^[6] It is sub-titled Rylan’s Supersized Celebrity Sunday.

Also a spin-off show, Big Brother's Bit on the Psych would be aired on Saturday nights (instead of BBBOTS), with guests and psychologists examining housemates' behaviour during the week, hosted by AJ and Iain Lee. This show is similar to other psychology-based shows that have previously aired, most notably Big Brother: On the Couch shown during BB8 and was hosted by McCall.

AJ did not return to Bit on the Side in January 2014 and was replaced by Rylan as the sole presenter on the days that Emma was not working. He also took over presenting Bit on the Psych alongside Iain Lee who was promoted to a regular co-host. During the January series, Carol McGiffin was a regular panellist however, she was replaced by Luisa Zissman from summer 2014.

For the 15th series of Celebrity Big Brother in January 2015, Bit on the Side was cut down from 6 episodes a week 5 episodes a week. During Big Brother 16, Channel 5 announced that the show would be given an extended slot on Monday evenings and would be renamed Big Brother's Bigger Bit on the Side; the show featured extra analysis of the housemates, more exclusives and more celebrity guests. There is no news on whether the extended editions will continue for Celebrity Big Brother 16.

In August 2015, it was revealed that Bit on the Side would revert to its original 7 nights a week format for the 16th edition of Celebrity Big Brother. The weekday episodes would air on Channel 5, with the weekend episodes airing on 5*. The Weekend Edition was titled Big Brother's Bit on the State Side and was presented by Rylan Clark-Neal.

The weekday shows feature a panel of guests. Panellists that have appeared on the show, so far, have included many ex Big Brother and Celebrity Big Brother contestants, amongst other celebrities not directly linked to Big Brother such as Kate Walsh and Jay Camilleri from E4's Dirty Sexy Things. Former Bit on the Side co-host, AJ Odudu, had also appeared on occasions, as well as former hosts Jamie and Alice (on weekday shows).

Celebrity Big Brother: Live from the House was a one-hour show airing straight after the Live Eviction show on Channel 5, at 10 pm on 5*. The show focuses on the aftermath of the eviction. The show airs before spin-off show Big Brother's Bit on the Side, which airs at 11 pm. It first aired as part of Celebrity Big Brother 9's schedule. The programme featured one hour of "live" streaming, which was absent from both Celebrity Big Brother 8 and Big Brother 12.

It returned for Big Brother 13, renamed Big Brother: Live from the House, as a 30-minute show on 6 July 2012 (four weeks into the series). For Celebrity Big Brother 10, the show moved to Channel 5 and now broadcasts twice-weekly for 30 minutes (or 60 minutes depending on schedule). An episode, featuring live nominations, on 17 August 2012 pulled in 2.22m viewers at 10 pm on Channel 5. This slightly outrated the night's highlights show which took 2.18m viewers. These two episodes were broadcast during the Celebrity Big Brother 10 series.

Channel 5 announced on 14 May 2013 that the live feed will be partly reinstated, for two hours per day. Big Brother: Live from the House aired each night from 19:00 on 5* during Big Brother 14, except for Sundays which only featured one hour from 20:00. Both launch nights featured 30 minutes of live feed after Bit on the Side from 23:30 on Channel 5 and this will continue after every eviction during the series.

On 26 June, it was announced that the daily live feed on 5* would be axed and replaced with other programming, starting 6 July 2013.^[7] However, two days later, it emerged that the final daily instalemnt of Live from the House would now air on 30 June at 8 pm (a week earlier than originally planned).^[8]

For Celebrity Big Brother 2014, Live from the House was axed online from midnight to 2 am and replaced with a 30-minute edition of live streaming every Friday night from 11:30 pm on Channel 5.

Channel 5 again axed Big Brother: Live from the House during the fifteenth edition of Big Brother. This was to make way for order for Channel 5's new dating show Stand By Your Man meaning as with Celebrity Big Brother 8 and Big Brother 12, live streaming was completely unavailable to viewers.

Prior to the launch of the fourteenth series of Celebrity Big Brother, Channel 5 announced that Big Brother: Live from the House would make a return to Channel 5 airing most nights from 12 midnight after Big Brothers Bit on the Side for the first week of the series.

For the fifteenth series of Celebrity Big Brother in January 2015, Live from the House will again air after evictions on Channel 5. This then continued on for Big Brother 16.

Prior to launch of the sixteenth series of Celebrity Big Brother, Channel 5 announced that Live Feed would be reinstated on sister Channel 5* every week night for 1 hour at midnight until 1 am. This will also be joined by the 30 minutes of live feed on Channel 5 after each eviction night, meaning there will be 90 minutes of live feed every eviction night and 1 hour every other week night.

These are a collection of shows that are shown a couple of days before the live launch of an upcoming series. They are usually recaps of previous series and catchup of previous housemates. Dermot O'Leary was usually the host until his departure from the show in 2008.

OK! TV: When 'Bruv Takes Over was hosted by Jeff Brazier and Jenny Frost live from Elstree. The show launched from the Big Brother compound at Elstree Studios on 17 August 2011 with a preview of the new house. It provided updated news, gossip and discussion on events in the house with a variety of celebrity guests dropping in.^[9] However the show was axed due to low ratings and Channel 5's contract with ITN being withdrawn.^[10]

Big Brother Live was live streaming from the House.

It aired mostly on E4 for the Channel 4 broadcast, and sometimes for 1 or 2 hours early in the morning on Channel 4.

The feed was presented as live, but was actually transmitted on a 15-minute delay to enable producers to censor any material that is inappropriate.

A Big Brother Special is a general term that is used to describe any live non-eviction episode hosted by Davina McCall aired in place of the daily highlights. Big Brother Specials typically involve the introduction of a new housemate, a twist implemented by Big Brother, a culmination of a task, or live nominations. The Specials were discontinued in 2010.

Big Brother's Little Brother (also known as BBLB) was a magazine television programme that aired from 2001–2010 on Channel 4 and E4, running in conjunction with each series of Big Brother. It was presented by Dermot O'Leary until January 2008, then by George Lamb from June 2008 – January 2010. For Channel 4's last series of the show, Emma Willis joined him.

Between 6 June and 25 July 2008, Zezi Ifore was a co-presenter, but was soon removed.^[11]

The programme looks at Big Brother-related activities outside the House and features interviews with celebrities, journalists and friends and family of housemates, and sometimes recently evicted housemates. It also gives updates to events in the House, including announcing on Mondays who is up for eviction. The show is filmed in The George Lucas Stage at Elstree Studios, which is only a short walk from the main house itself.

The show was first aired on 29 May 2001 as a part of Big Brother 2. Natalie Casey was a co-host with O'Leary for the first week that year. It was shown every Sunday morning as part of Channel 4's T4 slot as well as on E4 during the week.

For Celebrity Big Brother 4, broadcast in January 2006, Big Brother's Little Brother was moved to a morning slot of 8 am on Channel 4 and renamed Big Brother's Little Breakfast. It was moved back to its previous timeslot on E4 for Big Brother 7 and subsequent series.

Over the years, Big Brother's Little Brother has had many features introduced, from quizzes to secret cameras. The following is a list of some of the items the show has launched:

• The George Lamb Diary Room Challenge – A quiz and challenge feature run during Celebrity Big Brother 6 to determine the ultimate BB Superfan. The winner gets the chance to have an access all areas tour, meet Davina, and go into the Diary room for a chat with Big Brother. The final round took place on Tuesday 20 January^[when?] and featured the winners of the 2 semi-finals. Sonny Sleight from Canterbury was the first contestant to reach the final, eventually joined by Richard DeGottal. After first participating in a quiz which Sonny won, a 'superfan spacehopper race' took place outside the house itself. Richard pipped Sonny to the post and a chilli eating contest tie breaker took place. Richard eventually won but both contestants got the chance to meet Davina, enter the house and meet the housemates after the competition ended.
• The George Lamb Quiz of the Decade – A quiz feature during series 10 celebrating Big Brother's 10th Birthday and aiming to find the ultimate BB superfan from 3 viewers each week
• Big Brother's News 25 – 24 Hour News And Then Some – featured on series 10. Lamb reports on recent news items, with accompanying video clips. In Celebrity Big Brother 2010, this was changed to Hot News.
• Little Brother's Big Answer, formerly known as Little Brother's Big Shout and BBLB Forum – At the start of the show, viewers are invited to call, text, e-mail, and appear via webcam to give opinions on topical issues in the house. This is the final item on the show, and the discussion will usually include any celebrity guests that appear on the show. Zezi often complains about the computer not working. This feature did not reappear during series 10.
• The Insider – a man that stands behind a wall of frosted glass. The Insider often reveals exclusive news, such as nominations results and unexpected twists or tasks. The Insider's identity is unknown. He is not in BB9.
• A Hidden Camera section, where footage is shown from a camera hidden within an object in the house. The first of these was Fridge Cam, which appeared during the third Celebrity series. Gnome Cam followed in (BB6), where a hidden camera was placed within a garden gnome. Queen Cam was hidden in the eye of a portrait of Queen Elizabeth II, and, most recently, Bunny Cam was added to a rabbit-sculptured topiary. Bunny Cam was later destroyed by BB7 housemate Glyn as he used it to climb down from the roof of the house (not on show). In BB10 a toy helicopter was flown over the house several time throughout the season and contained a hidden camera. It was known as Heli Cam.
• The B-Team – A parody of the A-Team, four ex-housemates present a video clip, in which they interview people about their thoughts of the events in the house. It originated in Celebrity Big Brother 5 with former Big Brother 7 housemates Glyn Wise, Lea Walker, Shahbaz, and Spiral. For Big Brother 8, Walker was replaced with Nikki Grahame (not on show).
• That Gameshow Thing is a gameshow between Emma Willis and BBLB guests/ex-housemates.

BBLB was axed after the move to Channel 5, although it was initially said to return. It was replaced with Big Brother's Bit on the Side, which is said to be a combination of BBLB and BBBM.

Big Brother's Big Mouth, formerly named Big Brother's EFourum, was introduced with Big Brother 6 and was hosted by Russell Brand. The first series of the show was broadcast at 7:30 pm on E4 before being moved to a post-watershed slot, immediately after the Channel 4 highlights show, where it has since remained. A studio audience of fans and two celebrity guests discuss the latest happenings in the Big Brother House, while viewers are able to contribute via phone, e-mail, text polls, or by leaving a message on the 24-hour "Mouthpiece" rant line.

As of 2007, Brand no longer presented this show and the guest presenters listed below hosted the series 8 programmes. James Corden and Mathew Horne fronted the show during January's Big Brother: Celebrity Hijack; only returning for Week 9 of the 2008 series. During this series, the show was temporarily renamed Big Mouth with Davina when it was fronted during the final week by Davina McCall. After his week one and twelve stints on the 2008 Big Mouth, Jack Whitehall presented the 2009 Celebrity Big Brother edition full-time. McCall was the host for the 2009 series, which had a revised format and was moved to a weekly hour-long slot after the eviction show. She then continued to host the programme for its final series in 2010.^[12]

Channel 5 announced that the programme would not return in 2011, but a replacement called Big Brother's Bit on the Side was created. It was a mixture of Big Brother's Big Mouth and Big Brother's Little Brother.

A similar spin-off was introduced in the 2008 Australian version of Big Brother. However, Big Mouth has been used as a replacement of the "Adults Only" program, which has been broadcast at a later time slot, in an uncut and unrated presentation.^{[citation needed]}

Big Brother's Big Mouth also had a Bulgarian version during Big Brother 3 Bulgaria, and it returned with a new concept for VIP Brother 3. In 2014, the show aired for the third time, covering VIP Brother 6 and Big Brother All Stars 3.

During the series presented by Brand, several regular characters were featured on the show.

That Whale: That Whale is an anthropomorphic whale who speaks with a Scouse accent. He shows little interest in Big Brother but seems adamant that he has a right to be on the show and still turns up regardless. Due to his obnoxious behaviour, he was asked by Brand to no longer come on the show. His trademark saying is "You Shithouse!" He only comes on the show now to find another male to make love with, since he came out as a homosexual.

Rosebud the Horse: Rosebud the Horse is a very polite and well-spoken character who allegedly lives with Brand in his home, in which he works as his slave and is often mistreated and forced to carry out perverted misdemeanours by members of the "Womanising Circuit" including Beppe di Marco, Dean Gaffney and David Walliams. He dresses in the style of a country gent, with tweed jacket, smart shirt and tie. He is often treated badly by Brand; in one episode he slapped him in the face.

Little Jon Connell: Little Jon Connell (born 1989 in Liverpool) normally appears in a scientist's lab coat to conduct a variety of experiments. His contraptions, which illustrate a number of Big Brother-related findings based on his scientific research, are regularly vilified and destroyed by Brand. Jon Connell is known as a Big Brother expert, having appeared on the show since the age of 15, first as a panellist on EFourum and then later in a regular slot entitled "The Connell Files".

Little Paul Scholes: Little Paul Scholes was a small doll with ginger hair, a nasal voice and snub nose, in a reference to the football player Paul Scholes. The doll was usually in the programme for a few minutes after the break in occasional shows and has a short conversation (often centring on his mistreatment) with Brand, usually resulting in him being hit off the bench or sat on. He died in the final Big Brother's Big Mouth of Celebrity Big Brother 2007 following the live final.

According to Brand, when he recorded a one-off special charting the previous seven series of the show, all of these characters have died. This was Brand's last time presenting as a Big Brother host.

Russell's ballbags: Russell's scrotum, which seems to live a sensational life separate from him. One of them is the "younger, shyer bag", and the other is the "older, more confident bag". They were characters throughout series 7 and were replaced by some new "Dicksacks" for the 2007 Celebrity edition of the show.

Big Kenneth: A friend of That Whale. Big Kenneth has appeared on the show once with That Whale in an attempt to beat up Brand and has also been round to Brand's house in an incident that may have led to an assault upon Beppe.

Big Brother 8 saw the introduction of the "Eyepiece", for which viewers were invited to send in their views via mobile phone video messaging. During this series, the show aired four nights a week with a series of guest presenters hosting the show for weekly stints. These were:
