Celebrity Big Brother
Emma Willis and Rylan Clark

The long-running reality game show's first celebrity spinoff debuted on Channel 4 in March 2001, with a cast including Anthea Turner, Vanessa Feltz and eventual winner Jack Dee. The following years saw numerous memorable moments and controversies - to name but a few, a forlorn Les Dennis's appearance in 2002 as his marriage to Amanda Holden broke down, John McCririck's Diet Coke-related silent protest in 2005, MP George Galloway's unlikely friendship with Rula Lenska in 2006 and a record number of complaints to Ofcom in 2007 over Jo O'Meara, Danielle Lloyd and Jade Goody's questionable and controversial treatment of Shilpa Shetty.

Channel 5 now airs Celebrity Big Brother twice a year in January and August. Emma Willis hosts the January 2015 edition, which has a twisted fairytale theme, with Rylan Clark presenting spin-off show Bit on the Side.
