When my kids were younger I told them how, when I was a kid in the 50s/60s, we only had one TV in the entire house, and the programs were only shown in Black and White! Also mentioned that we had one phone on the first floor and one on the second floor. Only one car that Dad took to work everyday. Stores were not opened 24 hours, and not even opened on Sundays. No microwave, no cable TV and no VCRs. My smartass son asked if we had electricity and indoor plumbing when we were growing up!
They could not imagine living like that (and that conversation was even before the advent of computers, cellphones, ipods, etc)!
I actually did look at some of our TVs tonight (we have 6 and there are just three of us living here now ) and all of them still have buttons for manually changing the channels and volume level.
