The industry often credited with being the driving force behind (no pun intended) new technologies is now suffering from them. The pornography industry, which has long been growing alongside the Internet since the early days, has hit a wall in recent years. DVD sales and rentals have dropped by 15 to 25 percent in the last year, according to industry estimates, and some believe that it could fall further if the industry doesn't catch up with new online trends.

What's the driving force behind this change? As more and more of the general public comes online, they are finding newer and cheaper ways to get their adult content fix. Just like the masses have flocked to sites like YouTube to watch professional clips from their favorite TV shows, video blogs, crazy stunts, and amateur movies, the adult audience has ditched DVDs and pay-per-view television to flock to similar sites. For example, PornoTube is a user-submitted video site of growing popularity that functions in the same way that YouTube does, complete with free, streaming videos.

Not just that, but increasing broadband speeds and wider adoption means that folks who once merely watched adult content are now able to create and upload it easily to sites like PornoTube for a fraction—or none—of the cost that it takes to make a professional video. "People are making movies in their houses and dragging and dropping them," CEO of adult payment processing site GoGoBill.com Harvey Kaplan told the New York Times. "It's killing the marketplace."

While online revenue for the professional adult industry has never been something to sneeze at, AVN Media Network's Paul Fishbein added that growth in the online space isn't happening quickly enough to make up for the drop in video sales—USA Today reports that Internet-based pornography sales grew by only 14 percent in the last year. Professional studios told both publications that they are attempting to catch up with the shift in public consumption trends by selling more online downloads and revamping their web sites to be more useable and professional. Some are hoping that the "quality" of their professional videos will win out with the public over those produced by amateurs. "We use good-quality lighting and very good sound," Red Light District president David Joseph told the New York Times, yet the company reports a sales drop of 30 percent over the last two years.

Somehow, we get the feeling that today's adult video aficionados aren't exactly dying for the return of artistic lighting.

In a way, the problems that the pornography industry is facing now—competing with the flood of cheap or free amateur content—could foreshadow problems for the rest of the content industry. TV networks have already realized that they need to start moving content online in order to stay on top of consumer trends, and so far, the online audience still generally prefers professional shows to options provided by amateurs.

Creating amateur TV content is significantly harder than creating amateur pornography—finding someone to have sex with and placing the video online is nothing compared to writing, acting, and editing a decent TV show. But if the quality of amateur movies and TV shows gets better and it begins to overshadow the "real" industry, there could be some frantic TV network execs out there.
