It appeared to me we are just like the computer game industry and they are still doing good!
THey give DEMO of their game (just like a tgp gallery - a sample) and then people can buy the game (buy an XXX membership) or alternatively they can download the game on kazzaa (just like XXX can)...
it still works for game companies and they are still existing so maybe free porn doesnt affect XX industry as much as people say....
