Old children's programme's in top 100 (8)

Ross

I believe the answer is:

trumpton

'old children's programme's' is the definition.
(1960s children's TV programme)

'top 100' is the wordplay.
'top' becomes 'trump' (both can mean to beat or outdo).
'100' becomes 'ton' (I've seen this in other clues).
'trump'+'ton'='TRUMPTON'

'in' is the link.

I've seen this clue in The Independent.
