Oh yes, I remember the days of B & W TV, limited channels, no remote control and having to take tubes to the store to test them. Did anyone put "aluminum foil loops" on their rabbit ears to improve reception?
Most of the stores that carried TV Tubes had a free machine where you could plug your tubes into & hit the test button. The top of the machine had a least 20 different type of sockets where you had to find the one that fit your tube through a small reference manual attached to the side.
We had the regular channels (ABC, NBC, CBS & a couple others) & that was it. No recording devices meant when a program you wanted to see came on the night you wanted to go out, you had to make a choice.
So nowadays we have cable or satellite reception with about 200+ channels & you still hear kids say "There's nothing on TV!"
