I don't remember any of these being "driven" by porn. The first applications weren't porn-based. Maybe live video--a split second after seeing the tech for the first time, probably 99% of guys were thinking of _applying_ it to porn. But, even for the usual money-grubbing startups, there was plenty of money coming from non-porn sources. Probably no different than the invention of camera, tv, videocamera, etc. and you wouldn't say porn drove that.

Just because things can be used for porn, it doesn't mean that it was porn that has driven their progress.
