Benny Hill and nipples

[TV time]

I used to watch Benny Hill on American TV and recently I rediscovered it on BBC America and this last weekend I discovered something that had not been there before or at least I had not seen before - nipples (and full butt cracks too for that matter).

In the past I had seen hands over boobs, cleverly placed towels and such, but never nipples and butt cracks. Did Hill become risque as the programs went on or did American television edit the programs or what?
