Dang! I qualify to answer this one!
The entire computer thing has come about in the last 50 years. Things like floppy drives and CRT monitors where the latest & greatest then have gone extinct already. The Internet, wireless technologies, laser printers, ink jet printers, usb drives, all the media cards (SD, XD, MMS, etc.) did no exist. There was no internet, if you had to research a paper, you spent hours in the library. Every home had a set of encyclopedias and a couple of dictionaries. Or you went to the public library.
Electric typewriters (which were new then) have been replaced by word processors and then computers. Typewriter erasers and carbon paper went bye bye.
Microwaves in the home were high tech! Cameras used to be film only. And all music used to be on records, then 8 track tapes, then cassette tapes, then CD's and now mp3.
Magnets, lasers, electronic circuit boards, resistors, all kinds of chips are all new technologies within the last 50 years.
I made the joke to my husband about 15 years ago that before long we would have the power to fly the Space Shuttle from a laptop. The first computers used by NASA for those early flights had less computing power than a calculator does now days. When thinking about what little they had to work with, it's really quite amazing!
Cell phones didn't exist; we all had these old black rotary dial phones. When touch tone came out and the phones got smaller and sleeker, we thought we'd died and went to heaven. Then came cordless and answering machines! Pay phones used to be everywhere, in nearly every store, gas station.
All we had for TV was what the broadcasting companies put out. Cable didn't really exist at first, everyone had their old antenna. VHS was huge! We could watch what we wanted, when we wanted! Then the VHS vs betamax battle. VHS has given way to DVD and DVD to Blu ray.
It is quite amazing to track some of the changes in tech and how it was affected our daily lives.
