Wes Craven produced a Marilyn Chambers film.

"Deep Throat" was made with mob connections. This film is considered the most famous porno of all time, but that's because it was financed by two of the Colombo family of the Cosa Nostra.

Camcorders led to the rise of amateur porn.

Adult theaters were less profitable than peep shows.

Video stores relied on their hardcore to survive. Because chain video stores like Blockbuster refused to carry X-rated material, private video rental stores found it a necessity to carry a back room. Before the internet, EVERYONE wanted their porn. To not offer an X-rated section in your store would be suicide, as more patrons came looking for adult material than not.

J. Edgar Hoover had one of the largest collections of stag films.

Playboy photographer directed the first "nudie cutie" film. Heffner's Playboy introduced America to sex as a mass-consumption commodity. Russ Meyer was one of his photographers, who made the first porno film to gross over a million at the box office.

Stag films were considered an acceptable custom in political institutions and fraternities.

Porn was the reason VCR's and VHS tapes became successful. The movie industry didn't want films to be viewed at home as they saw it as major competition. Thanks to pornography, all manner of indie companies were making a killing on VHS, since it was cheaper than Beta. Soon VHS became the main home media.

Online content reduced porn movie productions. Official porno industry studios find it harder to make money off their work when so much is offered for free and anonymously, online.
