Having already fronted Children's TV show 'The Ant and Dec show' on BBC1, which ran for 2 series, followed by a stint on Channel 4 with the edgier 'Ant & Dec Unzipped', The pair continued to work in children's television, fronting ITV's saturday morning children's programme SMTV Live. After leaving the programme in 2001, the pair branched out to front other shows, including game shows – Friends Like These, PokerFace and Push the Button – talent shows – Pop Idol, and Britain's Got Talent – and entertainment programmes – I'm a Celebrity...
