If you want to point to a single thing that lead to the demise of this business, I'd point to Cogent.
Once they got into the bandwidth market prices started dropping like a rock and never came back.
The people who gave away free porn in the past didn't give away less because they had business sense or any shit like that, they only gave away what they could afford to because bandwidth costs were so high. Free hosts had file size limits, etc.
The amount of free porn available was constrained by the cost of bandwidth.
At <$4/mbps you can give away full free DVD's and make a small profit. At $40/mbps you can only give away about 15 pictures and still make a profit, forget about movies.
