An advantage of Beta. The blanking interval trick for the original Macrovision didn’t work on Betamaxes.
Putting Macrovision in VCRs was a voluntary thing–I had ones without it–and made copies of every movie that I rented (RCA outputs of one VCR into the RCA inputs of a second one.)
When I went to college in 1969 I brought a reel-to-reel tape deck, and copied the albums my friends had. So copying went on long before there were decent cassette decks.
When WBCN in Boston had rare tape night, the record stores had sales on tape so that people could record the rare content, so I wasmn’t the only one doing this.
I think the end of the era mostly coincides with the coming of age of broadband and cheap storage.
