Some of the largest adult-entertainment players in cable TV are struggling online. The sheer volume of established competition is staggering, having multiplied like rabbits almost overnight. Today more than 4 million adult-oriented Internet Web sites offer pictures and video to titillate every imaginable sexual taste. As the number of sites has surged, they're increasingly being fortified with unfiltered pictures or partial video clips, creating a flood of saucy -- and free -- online content. And if the content isn't free, it's typically priced to reach a mass audience. Moreover, the category is experiencing a new influx of user-generated content. Millions of amateurs, sporting little more than digital video recorders and poor lighting, are also changing the fundamental business dynamics of the pornography industry by seeking nothing more than exhibitionist notoriety -- and not charging a cent.
