I was watching a YouTuber I watch regularly who shows off and explains both old and new audio and video technology. Mostly vintage though. It got me thinking about when I was a kid watching movies on vhs. Then I started wondering how did they make millions of copies of a movie for home release? I tried googling it, but all I found were old forums where it was explained in very technical terms that i couldn’t wrap my head around. How are vhs tapes duplicated en mass for home release?
