Celebrity Big Brother 2007, also known as Celebrity Big Brother 5, was the highly controversial fifth series of the British reality television series Celebrity Big Brother. The series was broadcast on Channel 4 in the UK (also on S4C in Wales), from 3 January 2007 and ran for 26 days with the finale on 28 January 2007. Davina McCall returned as host. It was the first Celebrity Big Brother series to be shown in the 16:9 widescreen format.
The series saw the return of Jade Goody, who became a celebrity after appearing on the third regular series of Big Brother in 2002, arriving with her boyfriend and mother, it was the first series where family members could enter the house together.
On 16 January 2007, this series had attracted the largest ever number of public complaints to the UK broadcasting watchdog Ofcom about a Big Brother series. The complaints received detailed concerns that housemate Shilpa Shetty had been subjected to bullying.Jade Goody, Danielle Lloyd and Jo O'Meara's behaviour towards Shetty sparked widespread anger and demonstrations in India, where the alleged racism was reported on the news, and led Big Brother's main sponsor Carphone Warehouse to suspend its sponsorship of the show. As of 19 January 2007, a Channel 4 spokesman agreed that participants should be made aware of the controversy, which would probably explain the subsequent statements and apologies tendered by the housemates and their complete lack of surprise after learning about the latest eviction.
On 28 January 2007, Shetty was voted the winner of Celebrity Big Brother 5 with 63% of the final vote. Due to the furor, Celebrity Big Brother did not return until 2009; in 2008, the show was replaced by the much less publicised Big Brother: Celebrity Hijack, which was broadcast on E4 only.
