I suspect the changing society has a lot to do with it. Porn used to have to be delivered in brown packing envelopes, and girls wearing tankinis was scandalous. Now we've got 16-year-old celebrities pole-dancing on broadcast TV, and no one bats an eye at crazily short skirts so long as it (barely) covers everything. As we become a more and more sexualized society, the idea of paying for porn seems sillier and sillier. And as our medium changes, the ideal content size changes. It used to be that you could only get an hours-long movie because that's the format TV and tapes worked in. But you only need 10 minutes of it. So as we move to the Internet, the same thing happens to porn as happened to music - the filler becomes extraneous. I don't need the whole album, I need the singles. I don't need the whole movie, I need the best scenes. There goes at least half of your work. This moves the "porn formula" from "any decent looking chick in a two-hours-long movie" to "absolute stunner doing a few 10-minute scenes", which completely trashes the industry.
