And that includes gambling / gaming and so on.

Right now I think the major players in the market have all gone through several boom-bust cycles, and are concentrating on billing and other financials.

Some of the larger ones own their own IPSPs and are facilitating payments for third parties, ironically most of them non-adult. This is to manage the charge-back rates, because historically large adult companies have been literally blown up by taking their banks down.

I used to be fairly close to people working in the adult business, so my knowledge is at least a few years old, the innovation right now is centered more around business models, finance, diversification and other non-technical items.

I think that is in part because all the basic components to run an online business are now well understood and there are plenty of ways to deliver media.

edit: maybe mobile devices will really create a shift, but from what I've seen so far it will be an incremental thing rather than something that just hits one year and will leave the way we interact with online resources unrecognizable from the year before.

I doubt if there will be any major technological development, inside or outside porn until we hit something like 'the street' from Stephensons novels.

One of the porn company's tech guys claimed they were the first to pull of live HD streaming and they had a TV network calling for consultation.
