Actually, my buddy Eric once picked up a cassette from a flea market that was just someone recording local radio shows from 1987. He said it was like a time capsule, you know, with ads for products that don't exist anymore and DJ banter about events everyone forgot. For weeks, he'd listen to it on his walkman during his commute, which honestly sounds way more engaging than most podcasts today (no offense to podcasters). The thing is, that random tape introduced him to music and topics he'd never seek out on his own, which is exactly what podcast apps try to do with algorithms. So yeah, the flea market tape was his personalized, analog recommendation engine, complete with static and the occasional tape hiss. It's kind of wild how much curation and discovery happened by chance back then, without any likes or subscriptions.
