VCR was out in the late 70s: https://en.wikipedia.org/wiki/Videocassette_recorder https://en.wikipedia.org/wiki/Videocassette_recorder I doubt it was just porn though. I believe that simply getting teenagers / young adults inside for long periods of time (and not just for the purpose of abusing drugs / alcohol) is a big victory (for crime stats, not society in general).
