Moderately interesting facts:

Sony only stopped selling Betamax tapes a year ago...

David Attenborough used VHS tapes to help edit Planet Earth II

The trouble with that is that resolution is limited on VHS and this make repurposing the content for future use on say HD or UHD difficult. This is why a lot of 1980s programmes shown today look rubbish, basically they are 335 x 576 luma and 40x240 chroma (less chroma info as eyes fill in the blanks). Super VHS from 1987 onward was a bit better.

But go back to film shot on celluloid from the 1930s onward and you can get great looking content- it might need a digital clean up and despeckle, but the resolution is much much higher, even than BluRay/4K - that why you could blow it up onto a cinema screen. Basically it's an optical rather than digital process.
