When did the radio become popular?

Sometime in the 1880s, Prof. Heinrich Hertz succeeding in generating long-wave

electromagnetic radiation and then detecting it all the way over on the other side

of the laboratory, without wires. Having had a great day, he didn't want to let

anything spoil it, so he took the phone off the hook, flipped off the light, listened

to the 11:00 news, and went to sleep.
