That’s because nobody *has* a Betamax VCR save for a tiny few people. Betamax crashed and burned as a consumer format long before the 80s was out - in fact, long before most Americans even *had* VCRs.
Sure but that never stopped the professional market. Lotsof Betas were sold to video production houses etc. Those are now all on the secondary market with collectors and hobbyists. It’s a cult ststus thing and they are sought after in that world.
Just look up anything with the word ‘vintage’ on ebay. It’s a license to print money.Anything old is sought after, usually by people with enough extra cash to have built a booming market.
For example, a Roland Juno 50 synthesizer. 5 years ago it got $3-400 at best. Today it’s headed north of $2000. Because it’s a famous name attached to old ‘retro’ musical gear.
It isn’t actually ‘worth’ a fraction of that. But they sell and resell in an upward spiral because people want the cool factor of ‘old tech’.
