The static on old CRT TVs with rabbit ears was the cosmic microwave background. No one in the last 25 years has ever seen it.

Last time I thought about static I wondered why colour TV didn't show colour static.

Turns out the colour signal was on very specific frequencies, and if it wasn't present, it would assume it was a black and white signal and turn off the colour circuit.
