That was a different time and
Jenna Jameson was unusual. There's no current-day equivalent to
Jenna Jameson who can guarantee by being on a video box-cover that you're going to make money. There's just so much less money in fucking on camera than there used to be. In the 90s you still had porn stores where they sold VHS tapes for $40+ apiece. Nowadays an account at videobox is $10 a month and the tube sites are free.
Lisa Ann for example isn't even making videos now cause she can make more money doing other stuff.
