The porn industry has already dumped an insane amount of money into VR and is presumably seeing quite a return, since the major players have only accelerated their pace of output. Just like with other technologies, porn companies have already driven the consumer innovations streaming VR video from the internet, capturing 3D 180 footage, and defining best practices for immersive content. I'm sure "novel" experiences are on their way eventually, but right now the money's being made just making 3D180 videos for mobile VR platforms.
