"WHEN the first man desired to communicate with another, the need for radio began.
It is as old as that, and as new as the next tick of the clock! To most, radio remains a mystery, to be turned on and off as we like. We turn the dial and listen if we are pleased; we switch it off if we are not pleased. Beyond this we ask no questions.
But what lies beyond the radio set in our living room?
From what strange land of nowhere come the voices of presidents and kings; the sound of music and laughter?
Unreal, but real —
Unseen, but heard.
What is this mystery of radio?"
