LOL! I was thinking about Larry King’s old late-night AM radio show, but whatever!
Seriously, I vaguely remembering reading Carl Sagan’s book “Contact” when I was in college. In it he discusses how early TV signals were the first radio transmissions to escape the earth.
I also think he might have touched on it in his public broadcasting series “Cosmos”.
vast distances will erode the signal and break it up. I don’t think anyone who is several light years away can get to watch anything.
