Big Brother (British TV series) series 13

There were 16 original housemates, eight men and eight women, who all entered the house on Day 1. Shortly after the first eviction of the series, Becky Hannon, one of three wildcard housemates, was chosen by the public to enter the house on Day 4. For the first time since ''Big Brother 4'', all housemates left the house as part of the game - no housemate left the House walked from the house for personal reasons or by being ejected. The only housemate not to be evicted by the viewer's Vote was Conor, who was bribed out of the house with half of the £100,000 prize fund as part of a Dilemma in the White Room.
Brian Dowling returned to host the main show, with Emma Willis, Alice Levine and Jamie East also returning to host spin-off show ''Big Brother's Bit on the Side''. This series was sponsored by hair product brand Schwarzkopf Live Color XXL. Though overall ratings were higher than the previous series, the episode broadcast on Friday 27 July recorded the lowest figures in the programme's history at just 615,000 (being broadcast at the same time as the opening ceremony of the 2012 Olympics), then the episode broadcast on 12 August recorded even lower figures at just 483,000 (being broadcast at the same time as the closing ceremony).
This series sparked much controversy, with Ofcom receiving a total of 2,085 complaints regarding the bullying and intimidating behaviour from Conor McIntyre, and 50 more complaints about the same from Caroline Wharram. Provided by Wikipedia
