Online pornography helped build the Internet. It was the cutting edge of e-commerce when sites like Amazon.com were just starting. By some estimates, about one-quarter of all Web searches are for porn, although stats are hard to obtain.

But now, experts say, even though it still has a lot of eyeballs, fewer people are paying to view

And why would I? The last site I subscribed to made a couple of minutes of a video available each day so that it took a week or more to see a 20 minute video in full and even then it played poorly. Other pay sites I tried had 2 or 3 good videos mixed in with a ton of recycled crap.  Now I can find a dozen scorching hot girl/girl vids with a quick search on Pornhub or Tube8.  I certainly don't want to deny performers a return on their work but until the paid sites are overwhelmingly better than the free sites I wouldn't expect porn consumers`s habits to change much.

Way too much free stuff out there, pretty much any theme you want is available on the tube and hub sites.
