The Internet is not only wreaking untold damage on newspapers, television and movies, but it also has damaged the business of pornography, the New York Times indicated today (Wednesday). Whereas in the past, full-length pornographic features attempted to present a degree of plot and dialogue, they now often amount to, as the Times puts it, "a series of sex scenes, loosely connected by some thread -- 'vignettes' in the industry vernacular -- that can be presented separately online." Moreover, web porn has also impacted DVD sales. Paul Fishbein, president of the AVN Media Network, an industry trade publication, estimated that three years ago, pornography generated $3.62 billion in DVD sales and rentals, but has fallen to half that amount today.
