2002 edition
For 2002, the show was resurrected, with ten half-hour heats and qualification to a 90-minute grand final show. The heats were presented by Tess Daly, and the grand final by Carol Vorderman again. There was also a format change in 2002, with tie breakers being replaced by "Codexs" after the mammoth tie-break in the 2001 show. There were also several spin off shows, such as Britain's Brainiest Footballer and Britain's Brainiest Cabbie after the success of the 2001 show. However the 2002 show was not as successful and Celador eventually announced that the series would not return for a third series.The winner of the 2002 series was Christopher Guerin.
