Betamax was a superior technology than VHS
Really?
Could record your shows longer? No.
Devices were cheaper? No.
Had more shows to watch? No.
Guess the only thing going for it was a few extra lines of resolution... Hmm.
4-6 hour TV recording won that battle with the common user.
Actually, it was porn.
Porn industry standardized on VHS, regular movie industry followed, everybody bought a VHS, nobody wanted two machines, Beta lost.
But, yeah, IIRC, the longer record time was the seller for why porn picked it.
