My television career has been entirely spent making programmes for children. There is no more important audience. All my programmes have been in the factual entertainment genre which is fast disappearing from children's screens because of its minority appeal. I hope ways will be found to support factual television for children in the future. They should always enjoy a rich and varied viewing choice."2007 BAFTA Children's Awards full list of winners: Animation: 'The Secret Show' (C Beebies/CBBC)Bafta Kids Vote: 'The Simpsons Movie' Channel of the Year: C Beebies Drama: 'That Summer Day' (Hat Trick/BBC One)Entertainment: 'The Slammer' (BBC One)Factual: 'The Wrong Trainers' (CBBC)Feature Film: 'Happy Feet' (Warner Bros UK)Independent Production Company: Aardman Animations Interactive: 'The Secret Show' (CBBC)International: 'Sponge Bob Square Pants' (Nickelodeon)Breakthrough Talent: Charles Martin, director of 'My Life As A Popat' Preschool animation: 'Charlie and Lola' (Tiger Aspect/C Beebies)Preschool live action: 'In the Night Garden' (Ragdoll/C Beebies)Presenter Barney Harwood 'Smile' (BBC Two)Special award: Mick Robertson Video game: Buzz!Junior Jungle Party (PS2)Writer: Bridget Hurst 'Charlie and Lola' Learning, primary: 'Espresso Education' Learning, secondary: 'Recollections: Eyewitnesses Remember The Holocaust' Short Form: 'Nick Big Green Thing' (Nickelodeon UK)CBBC me and my movie, in association with BAFTA: 'The Unwelcome Stranger Rosalind Peters' (aged 14, Norfolk).
