Blue Peter: 1958 onwards
The show has been popular with generations of kids thanks to the presenters, the pets, and the sticky back plastic creations. Occasionally struggles with a do-gooder/dullsville image: Blue Peter was an early champion of green issues, charity appeals and is generally keen on wholesome fun. Not that its presenters are always so squeaky clean: in 1998 Richard Bacon was famously sacked after a tabloid reported his cocaine habit.
