If you didn't know, radio was initially used for communication between ships at sea.
It's funny you should mention that. Decades ago when Casey Casem did the top 20 countdown he also did "dedications". A woman or man would dedicate a love song to another, and one such dedication was from a man to a woman saying they were "two ships that passed in the night".
I think radio will come full circle and return to the days when the broadcasting takes on a simpler job.
