Even in video/VOD mainstream is making advances and porn *may* be more innovative in that area but if so only just.
In other areas, as others have said porn is now a long way from being particularly innovative and I'd even disagree that porn drives innovation these days. That used to be the case but is no longer. When I first moved into porn 6 years or so ago porn could live up to that claim. These days porn thrives on repetition and jumping on the latest bandwagon until it's saturated and something else comes along.
