Political correctness wasn't as major. There were plenty of comments that are not allowed OTA now, but were used then. I still can't get over the use of the "N" word on broadcast tv, among other slurs and slanders.
Same with gay men and women too. Back in the day gay jokes were in and sometimes I would hear "f*ggot" on TV. Well into the 80s even on MTV one would see some rock star wearing a t-shirt that said "AIDS kills F*gs DEAD" and of course there was that Dire Straits video "Money for Nothing". Today with the exception of some religious programs and even then it is minor than the day it once was...well you can't get away with using such words thanks to social media.
