Funny story. Back in the 1960s porn shops invented loop booths. You'd pay a quarter and have five quiet minutes alone to watch an 8 mm porn movie. When the time came to switch over to video, the porn shops went with the cheaper option. The guys who made the tapes put them on VHS because the porn shops were the biggest market at the start. When guys went to buy dirty movies for home viewing they saw that most were only available on VHS.
I'm being liked and get a book suggestion. That is both random and pleasant. I'll order it from my local librairy and let you know whether you were right about my literature tastes. Thank you.
