What do you not see in the media and on TV cultural wise today you would have 2 decades ago?

When I look at old TV shows, movies, and films I see a lot of things that was common then that you don’t see now. Some of the stuff was because the technology changed, that is a given, but a lot has to do with straight culture. One of the things I noticed was that people were quick to whip out a cigarette and offer one to the other person because smoking was so sociable back then. Another was that married couples (you would never see any couple not married knocking the boots or boinking like bunnies), always had twin beads. If you happen to be old enough or you are a buff of old films and movies what cultural type differences you see in the old movies that is no longer around today?
