Anne Wood, creator of children's television series In The Night Garden and the Teletubbies, believes TV is often blamed wrongly for children's inability to express themselves.
She told Kirsty Young that, without TV, some children would have very little mental stimulation at home.
Anne Wood's interview with Kirsty Young on Desert Island Discs will be broadcast on Sunday 2 October at 1115 BST on BBC Radio 4, and repeated at 0900 BST on Friday 7 October. Listen online or browse the extensive Desert Island Discs archive.
