After the Beeb changed Ninja Turtles into Hero Turtles, the "obvious danger" to viewers of Dr Who was realised and it was decided to revamp the show into something less identfiable with scalpels. Delia Smith's Cookery Course was the new show but nobody tuned in and as a result it was soon cancelled. Anne Robinson explained all this to Tony Cutler on Points of View.
