The central pit, or courtyard, was standing room only, but it was surrounded by three tiers of stadium seating.
I have read that the largest contributors to the campaign against Prop 19 are the makers and distributors of alcoholic beverages, but certainly the prison industry also has a horse in this race.
But of course U.S. publishers do routinely revise books for the American market. For example, "Harry Potter and the Sorcerer's Stone" in the U.S. was originally "Harry Potter and the Philosopher's Stone" in the UK (which makes a lot more sense, if you know any history at all - apparently something the publishers don't expect from American readers).
Bonch, I don't cite a source because I was there: I experienced it firsthand; I am my own primary reference. Make of that what you will. I sold VCRs when they first came on the market; I remember the introduction of both Betamax and VHS, and I had friends who were starting video rental businesses back when the studios were still trying to prevent them from renting out movies.
This is not as big a deal as our discussions might make it appear. Porn was certainly not the only factor, but it was a strong driving force, and early on a major profit center in my friends' stores. Prior to the advent of the VCR, porn on film was rare and a huge hassle. Just as you say, suddenly it became cheap and easy to produce and distribute, and there was a huge demand. And yes, it was more private - no more stag nights at the men's club.
As for the Internet, I hope nobody is claiming that porn is responsible for the growth of the World Wide Web. But from the days of the first bulletin boards, it made up a substantial fraction of all online content, and that remains true today. It does not drive the development or introduction of new technology, but unquestionably plays a significant role in its adoption.
An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.
