Today in History: June 11

The inventor Edwin Howard Armstrong gave a demonstration of FM radio to an audience of engineers and everyday listeners 80 years ago today.

Anyone who has listened to an AM broadcast for more than a few hours has encountered its drawbacks: crackles, hisses, static-y noises, pops.
