80s kid here. Ugh, I will NOT miss analog broadcast television. EVERYTHING always looked like it was in a blizzard of static.

Cassette/VHS Tapes: Remember these? I remember not being able to skip songs on a cassette tape (without fast forwarding and guessing), and having to get up and flip the tape over when about the fifth song was over. Also, tapes were notorious for jamming and then having to wind up the tape after it got all tangled in the player. As a bonus, VHS tapes were almost the same, and you had to rewind when you were done watching the movie. Plus they were pretty big and clunky.

Floppy disks: The REAL floppy disks. We had an old computer that played very basic games like Pac-Man, Hard Hat Mac, Centipede, and stuff like that off of these. They entertained me for many hours, but man, those games were tough and brutal for a kid my age. And a lot of them were never-ending and just kept getting harder and harder until it became impossible.

Rotary phones: We had one or two I think. Apparently, you can still buy them if you're into that vintage kind of stuff, but it took like a whole three minutes to dial in someone's number, and it was easy to mess it up.

Apparently, you can still buy most 80s things if you really badly want them enough (Fireball Island Board Game for $300 on Ebay! XD). Ah, the internet.
