Wow, people used to give me shit for *my* posts being way too fucking long.
More than enough companies give consumers what "they want." I don't think thats an issue; you can track down anything you want nowadays in a nice subscription package. Shit, I remember first surfing for porn back in '95 (at the tender age of 12) and being so shocked by the very few DP/gangbang photos out there. Now its a prerequisite for porn stars and proliferates on the web.
About the only thing that can save porn is a massive recession followed by a massive HIV outbreak taking out 75% of the companies out there and most of the old fart talent still running around.
Or companies figuring out how to maintain positive mainstream publicity to garner sales. No ones managed to do that yet (about the closest was Girls Gone Wild in my opinion if thats any indicator of the sorry shape of the porn market).
And personally I'd be much happier if everything went free. Seems to be the next logical step in human sexual evolution.
