Supposedly, the first group of content providers to colonize a new medium once it becomes commercially viable will almost always be the producers of adult-oriented material -- that is, porn. They will, of course, attempt to maximize their profits by flooding their customers with product. This, in turn, will drive up demand, pushing the new medium into the mass market, where economies of scale come into play and make it affordable for increasing numbers of consumers. As more consumers can afford the medium, more non-adult content becomes available, until finally the adult material becomes a niche rather than the primary content available. (But not before the media and Moral Guardians get ahold of it and create a moral panic about all that "smut".)
