Most of the complaints to the F.C.C. come from the Christian right. The networks probably decided it wasn’t worth drawing the heat.
Elton John thanks you. We were shocked that he could sing “The Bitch is Back” with no censoring. Ah, those were crazy days indeed! We were living in a new era.
Quite a change from the Rolling Stones mid-60s appearance on TV when Mick was forced to sing “Let’s Spend Some Time Together”, because of what was only* implied *by asking the girl to spend the night together. You know…[whispered] …fornication!
The OP’s question just reminds me of Peter Finch yelling, “I’m as mad as hell, and I’m not going to take this anymore!”

I don’t recall goddamn being said on broadcast TV (much if ever), but about 1980 there was a decidedly more prudish move in many media. Look at a typical Time or People magazine from 1976 to 1981 and compare one from about 1985. They almost always had a gratuitous bare breast picture (or see through blouse), however small, in every issue, but by 1985 those had disappeared.
