@elbanditoroso Damn! I was being Amerocentric again. I hate it when I do that. :-) My link only lists American films but you’re absolutely right. Other countries make movies too. Made for TV movies wouldn’t have been an issue in 1960 because the first one, http://en.wikipedia.org/wiki/See_How_They_Run_(1964_film) wasn’t made until 1964. But it’s certainly something that would come into play after that, and also cable movies, both made for TVish things and the kind of films channels that HBO make now that are really the equivalent of theatrical features. And then there are “direct-to-video” films, though they also wouldn’t have been an issue in 1960. Here’s an alphabetical list from Wikipedia
I’m not sure about who might track porn films though, and I don’t really feel like looking into it.
