The proliferation of 8 mm and Super 8 mm movie equipment during the 1960s meant that many people now had the ability to project movies at home. In the days before videotape, the 8 mm stag film - or "loop", as it was often called - was the only means to effectively consume filmed hardcore pornography in an exclusively private context. Home movies did have their advantages to seeing dirty movies in a theater: you could screen them at home for your wife or girlfriend in the hopes of getting her "in the mood", and perhaps best of all, you could collect them. It's these collections - often discovered posthumously, hidden in the back of dad's workshop - that have served to preserve the great majority of stags in circulation today.
