That sort of thing was disapproved of by many, but was unfortunately really common in the media in those days.
We had topless 16 year olds on page 3 of a national newspaper. Mandy Smith went on national chat shows as Bill Wymans 13/14 year old girlfriend. Comedy shows would routinely depict very young teens being perved over by older men, and it was portrayed as a lark, not creepy.
Saville often talked about his liking for young girls on camera. He hid in plain sight, didn't especially try to hide the fact that he was talking about teens.
