Hosts.
The show started being presented by Kate Thornton, but she left in Series 3 (2006.) Ben Shephard was hoping to present, but his offer was turned down. Instead, Dermot O'Leary took over in Series 4 (2007) and presented for 8 series, until his departure from the show in Series 10. Olly Murs and Caroline Flack became the first duo to host the show, but only lasted one season, mainly because they were very unpopular with the public.
