James McQuivey, a principal analyst at technology research firm Forrester, said in the VHS-versus-Betamax war, porn provided a significant boost for the winning format.
He also noted the adult entertainment industry has often paved the way with new uses of technology -- such as streaming video on the Internet -- and said porn could help tip the scales in the current DVD format battle.
"If the porn industry wanted to break the logjam of HD-DVD and Blu-ray, it could," McQuivey said. "If they said 'We are going to go with HD-DVD' you would see a few million homes immediately go out and buy HD-DVD players. They have that power."
Sony screwed this one up last time too.
