Well, if tubes would go back to showing ONLY 5 minute clips then paysites would be alive and well. Maybe VR will end up doing just that given the cost/bandwidth/etc it would take a Pornhub or XHamster to release a full 25 minute VR video.
Maybe the "sweet spot" is where it all started: 5 minute (VR) clips but you have to join the paysite to see the whole thing. Ahh the good ol' days again?
PS: You rarely hear me bitch about such things. I'm adapting me arse off over here. LOL
