Porn Sites have always been on the cutting edge of Internet Marketing technology. Think about this -You think the biggies like ebay or Amazon came up with online payments? Nope. The Porn Kings did - back in the mid-'90s. "Electronic Card Systems" made beaucoup commissions for processing sales on a range of sites...like- promoters of the notorious Pamela Anderson-Tommy Lee sex tape.Yes the porn industry pioneered autoresponder campaigns. Except back in the Nineties it was more like unsolicited emails - spam. By 2003 it was out-of-control. One out of every spam email sent was for PORN sites.Before YouBoob took over the world of streaming online video, guess who did it first? Give the man a cigar. Yep - pornsites. They were the first to use streaming JPEG push video - video that ran in the browser and didn't require a plug-in.Again - pioneered by porn sites. But it was calledorThink. "What are you wearing?" - except for the first time you could see what she was - or wasn't - wearing.All you get-rich-quick Clickbank marketers owe a debt of gratitude to the porn industry for these annoying numbers.band - get it?

The Porn dudes developed the concept of top sites linking to generate traffic and were among the first to develop an affiliate revenue-sharing model.Know of any others? I'm sure there's more. Bring 'em on!
