I’ve exhausted my googling ability on this one, since every attempt to find a Bradbury story about television lands on “The Pedestrian” (IMHO, one of the most black and brilliant prognostications ever written).
The story I am trying to locate, though, and which I am reasonably sure is another RB work, is where the miner comes into town after several months in the desert and discovers that television has been wiped from the face of the earth by some kind of cosmic radiation event. People are being forced to talk to one another and it’s dangerous to mention that TV ever existed.
You know it’s annoying trying to find SF stories about television, because search engines inevitably bring back SF stories on television. That being said, this story does sound vaguely familiar.
Meant entirely in good humor - I’ve had two fails and so many instant answers I’ve lost count of them. (I’ve literally had answers in the time it took me to refresh the page.) Funny that this one missed, though, given Bradbury’s popularity in this crowd.
