A little history on the X rating and XXX rating... (History)
submitted by blumen4alles to History 2 days ago
Because the X rating was not trademarked, anybody could apply it to their films, including pornographers, as many began to do in the 1970s. As pornography began to become more popular and more legally and commercially tolerated, pornographers placed an X rating on their films to emphasize the adult content. [b]Some even started using multiple X&#039;s (i.e. XX, XXX, etc.) to give the impression that their film contained more graphic sexual content than the simple X rating.[/b]
This was from wikipedia (https://en.wikipedia.org/wiki/X_rating#United_States) but there is also a good documentary I recommend where I first learned about how the XXX-rating came to be, has lots of jews in it though:
[i]Skin: A History of Nudity in the Movies[/i] 2020 https://www.imdb.com/title/tt11245776/
The X-rated movies are now known as NC-17 btw
I wish I could see the X-rated version of [i]RoboCop[/i]!
