I miss the instant channel switching on old analog tv sets. Everything now is digital so the switching is done with microprocessors, but on old sets you could flip through about 5 channels a second, as fast as you could press the button.
We had the knob but it broke off. So we had a pair of pliers sitting on top of the TV to turn the dial (from 2 through 13).
My friends weren't as poor so they'd have a converter box. It had an actual remote and that sound it made as it flipped through all the channels. I can't even describe the sound but if you know, you know it.
I had found one at home with only knobs, and at the time I dug that out of the attic, the only TV it could receive was state TV. An B&W. Still, It was amazing to me that i could even receive TV wireless. Turning those knobs felt... decisive!
