I remember YEARS ago, when I was a kid, changing the channel meant turning the knob to the next position where a copper switch contact would make. It would be an instantaneous connection but then you had to adjust the "fine tuning" ring to get the picture in clearly.
I remember YEARS ago when I was a kid and changing the channel was INSTANTANEOUS! Turning now is like waiting for the next ice age.

You had to what?! The first TV I ever had included a remote with it... then again I'm only 19 and grew up with technology.
