Children's television programmes will be broadcast on BBC One for the last time on Friday.

Shows like Blue Peter and Newsround will now only go out on the CBBC digital channel.

Andy Crane, who presented children's television on BBC One from 1987 to 1990, with Edd the Duck, said children's TV had moved on.
