Like Boomers through Millenials to varying degrees, with it being worse the younger you were in that spectrum, basically.

It's insane, but if you go back to popular movies and TV from the 50s and 60s they are pulling basically the same move. You could be a little bit bigger than was acceptable in the 90s but not much! I have to imagine the roots of it are in early 20th century advertising, but I don't know for sure.
