Fun Fact: I own porn I can't watch
One fun fact I learned when I was toying with Laserdisc is why it was so popular in Japan:  the humidity encourages video tape to grow mold[0] unless it's stored somewhere cool and dry.  I would love the room to play with more of the obscure / dead video formats but Laserdisc is enough for me.  Others here have recommended Techmoan[1] as a good source of vicariously seeing obsolete video formats.[0]https://lunchmeatvhs.com/blogs/blog/rescue-your-awesome-anal...[1]https://www.youtube.com/@Techmoan
