Playboy and the pill came along about the same time

NOT even the same decade.

In 1960, the first oral contraceptive (Enovid-10) was launched in the US market. First issue of Playboy - December 1953 (the Marilyn Monroe issue) so call it 1954. So, yes, different "decade" but certainly closer than you're implying. I thought they were about five years apart.
