However, it's because I believe many great consumer technology leaps were driven by porn: photography, home video, the internet, the smart phone, etc.
The smartphone??
I mean it was convincingly invented, if not widely used by IBM in 1993. It was made to look very impressive (albeit wired) in the late 90s by Olivetti. And of course PDAs approaching from the other end being more computer and less data. J2ME phones came out which were a pile of shit. Maybe you could get a shit game on them. I don't really know if Blackberries count: they were messaging first but did they have any generality beyond that? There was of course the legendary N900, and some impressive (for the time) yet deeply wonky Symbian devices.Then in 2007, Apple came out with a rather good dumbphone which was turned into a smartphone by Cydia, which Apple then got in on the game a year later (which is a bit weird if you think about it).
None of those were porn. It was all about connectivity and messaging and nerdy shit especially businessnerd shit (except the N900 which was real nerd shit). Then fashion, then just plain old usefulness.
I mean that's not to say people don't watch porn on a phone on a plane (shit head in 23A knows what I'm talking about you utter wanker, but not in that case literally thank god), but I don't there's a convincing case that porn had a significant role. Pocket computers were obviously useful, even more so with a data connection, and people had been trying to get them working for years before it finally took off.
