alt Hacker NewsI doubt that. Home video recording, while a new thing in 1981, was not substantially different from making personal mixtapes on tape from radio or vinyl records which had been popular for decades. My grandfather had dozens of 4 track mixtape reels he made in the 60s. You could even go further back and say it wasn't any different than taking a photo of artwork for personal use. You didn't have to be that young in 1981 to understand what home video recording is.
They had the ability to record video at home LONG before 1981. People had handheld "Super 8" film cameras ages before this, which they used to film their own home movies. Of course, this is a little different from videocassettes, just like LPs are different from audio cassettes, but it didn't take a genius to see that home video was going to move to videocassettes before long, they just needed cameras that could record directly to them instead of to film.
