VHS did more for the porn industry than anything else. Not only did sales increase, but the quality of movies did too. Unfortunately, many of the actors (and mainly female) did not enjoy the financial rewards until much later.

However, all good things must come to an end. Remember the 1980 song "Video Killed the Radio Star" by The Buggles? One could repurpose that tune to sing "Internet Killed the Video Porn". Waiting for the next leap in porn: VR.
