Most of us have watched a movie or some kind of video on DVD or Blu-ray. Older folk will remember VHS and (maybe) Beta. If you want to get a little deeper into old formats, there was LaserDisc (essentially DVDs but on 12-inch discs), CED (another form of video disc) and cheap VCDs that you’ll still find in Asian markets, featuring bad copies of bootleg movies.
I like to think of myself as somewhat of an aficionado of obsolete media formats, but until Tom pointed out this video, I’d never heard of VHD. This was video on vinyl.
