Happy Birthday FM

Happy Bithday (this week ) to FM RADIO.

At this time in 1941, W47NV in Nashville was the first to operate commercially while using the physics of Frequency Modulation transmission technology.

FM had been around for awhile, but ignored by the industry because of its "line of sight" aspect. AM was deemed superior because it could bounce its signal off the sky and beyond the horizon. But FM overtook AM in the early 70's, primarily because of its superior sound clarity. It played the role as the major source for music discovery throughout the 70's until the Inter-tube hit town.

For an interesting look at the history of the radio business, round up an old copy of Empires of the Air by Saratoga resident Tom Lewis.
