The X Factor (British TV series) series 5
season of the UK television series

The X Factor is a British television music competition to find new singing talent. The fifth series was broadcast on ITV from 16 August 2008 until 13 December 2008. Dermot O'Leary returned to present the main show on ITV, while Fearne Cotton was replaced by Holly Willoughby as presenter of spin-off show The Xtra Factor on ITV2. Simon Cowell, Louis Walsh, and Dannii Minogue returned to the judging panel. Sharon Osbourne left after four series and was replaced by Cheryl Cole. The series was won by Alexandra Burke, with Cole emerging as the winning mentor. Auditions in front of producers were held in April and May, with callbacks in front of the judges in June. The number of applicants for series 5 reached an all-time high with a reported 182,000 people auditioning. A number of well-established music acts from around the world, such as Beyoncé, Mariah Carey, Britney Spears, Girls Aloud, Take That, Il Divo, and series 3 winner Leona Lewis, performed during the live stages of the show.
Burke's prize, as winner, was a £1 million recording contract with Syco Music (a subsidiary of Sony BMG).
This brief starts where responsible research should: with the source description of “The X Factor (British TV series) series 5” as season of the UK television series. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the arts & letters register because the source frames it as season of the UK television series. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q1319991. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008.
Titles can refer to several editions, objects or performances, making precise identification essential before interpretation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
