 Is there still, I know there's G and R, are there still X-rated movies out there that make it to the public theaters? No, the X-rating was kind of a problem when the Motion Picture Association of America introduced it in 1968. They trademarked the G, M, and R, but they didn't trademark the X. As a result, the sex industry picked up X, and they were using it for XXX to talk about sex films.
