Big Brother: Celebrity Hijack was a special series of Celebrity Big Brother, a spin-off series of the British reality television programme Big Brother. It was broadcast on E4 from 3 January - 28 January 2008. A number of closely associated programmes also aired on the same channel. Dermot O'Leary - who had hosted Big Brother's Little Brother since 2001 - was the main host of Celebrity Hijack, and it was his final series of Big Brother. The series was announced on 8 October 2007 by Channel 4 and that it would be replacing Celebrity Big Brother in January 2008, due to the widely publicised racism controversy in Celebrity Big Brother 5. In 2009, Celebrity Big Brother returned to Channel 4 and no further series' of Celebrity Hijack were produced. The premise of the series saw one celebrity a day taking control, with the help of Big Brother; organising their own tasks, making their own rules and talking to the housemates in the Diary Room. They were in charge of a set of housemates, ranging in age from 18–21 years old and all having a special talent. The housemates competed to be the last to leave the house for a £50,000 prize. The series ended on 28 January where John Loughton was voted as the winner.

The X Factor is a British television music competition to find new singing talent, contested by aspiring singers drawn from public auditions. Created by Simon Cowell, the show began in September 2004 and has since aired annually from August/September through to December. The show is produced by FremantleMedia's Thames and Cowell's production company SYCOtv. It is broadcast on the ITV network in the United Kingdom and TV3 in Ireland, with spin-off behind-the-scenes show The Xtra Factor screened on ITV2. It is the originator of the international The X Factor franchise. The X Factor was devised as a replacement for the highly successful Pop Idol, which was put on indefinite hiatus after its second series, largely because Cowell, who was a judge on Pop Idol, wished to launch a show to which he owned the television rights. The perceived similarity between the two shows later became the subject of a legal dispute. The "X Factor" of the title refers to the undefinable "something" that makes for star quality. The original judging panel was Cowell, Sharon Osbourne and Louis Walsh. Dannii Minogue joined the panel in series 4, and Cheryl Cole replaced Osbourne in series 5 after her departure. After series 7, Cowell and Cole both left to judge the American version of the show whilst Minogue left the show due to commitments on Australia's Got Talent. Kelly Rowland, Tulisa Contostavlos and Gary Barlow then joined Walsh on the judging panel for series 8, though Rowland announced she would not return for series 9 and was replaced by Nicole Scherzinger. Osbourne later returned in 2013, replacing Contostavlos. Since 2007, the show has been presented by Dermot O'Leary, who replaced original host Kate Thornton. The show is split into a series of phases, following the contestants from auditions through to the grand finale. In the original televised audition phase of the show, contestants sang in an audition room in front of just the judges. From series 6 onwards, auditionees sing on a stage in front of the judges and a live audience. Successful auditionees go through to "bootcamp" and then to "judges' houses", where judges narrow down the acts in their category down to three or four acts to mentor for the live shows, where the public vote for their favourite acts following weekly live performances by the contestants.

Shattered was a reality television programme shown on Channel 4 in the United Kingdom. It aired in 2004.

They were competing for a potential prize fund of £100,000 though, at any point, if a contestant closed their eyes for over ten seconds, then £1,000 was deducted from the prize fund.
