1976. Porno booth loops on 8mm. No channel change either, one movie per booth. There was an old projector on a shelf over your head and it shot into a mirror in front of you. Lots of Swedish Erotica stuff with Deseree Cousteau, Seka, Aunt Peg, etc. These were little porno bookstores with booths in the back. Then when Misty Beethoven opened, my buddy and I snuck into the theater and saw wide screen porn. I saw a bunch of movies in the theater between 76-79. The first VHS porn titles I remember seeing were Sexworld and Taboo.
