Some highlights of those that apply to me:
Inserting a VHS tape into a VCR to watch a movie or to record something.
Playing music on an audio tape using a personal stereo.
Watching TV when the networks say you should. Tivo and Sky+ are slowing killing this one.
Rotary dial televisions with no remote control. You know, the ones where the kids were the remote control.
That there was a time before ‘reality TV.’
Blowing the dust out of a NES cartridge in the hopes that it’ll load this time.
Turning a PlayStation on its end to try and get a game to load.
Vacuum cleaners with bags in them.
Not knowing who was calling you on the phone.
Finding books in a card catalog at the library.
The rotary-dial telephone is something I really remember when I was a kid. I loved playing with the phone, listening to the noise it made while I spinned the dial.
I also saw the evolution of video games from NES to whatever we have now. One of my favorite games when I was younger was Jurassic Park for Sega Genesis.
