I can't believe how much things have changed since I was a kid. I remember regularly using these back in the day:
*Watching movies on VHS tapes. Also setting the VCR's timer to record programs (I did this regularly to record the Pokémon anime off of Kids' WB back in the early 2000s.)
*Using Apple IIe computers when I was in elementary school. On top of that, loading software via 5¼ inch floppy disks.
*Speaking of CRT TVs, I regularly fiddled with the rabbit ears on top of mine to get the best signal from whatever channel I was watching. I would also frequently surf through the entire VHF and UHF dials after a thunderstorm and discover stations that normally couldn't be received in my area (DX'ing).
*Listening to music via Compact Cassette tapes (yes, that's the official name for the once-common audio format. Everybody that's old enough has dealt with them at one point or another.)
*Gaming consoles that used ROM cartridges instead of discs, such as the NES, Super NES, N64, and Sega Genesis. Although I never used it, I remember the original PlayStation being highly regarded due to it using optical discs instead of cartridges.
*IBM PC compatibles running real mode DOS, complete with having to deal with the notorious "640KB limit" for RAM. (The original IBM PC series and the aforementioned Apple IIe date back to an era when there were many competing microcomputer architectures, nearly all mutually incompatible with one another.)
