Armstrong: the Tragic History and Physics of FM Radio

How Howard Armstrong created and detected frequency modulation (FM) radio and how it was so impressive that it actually caused his downfall!
Some links:
• Video
Very good video but, unfortunately, the methods that they described were not used by Armstrong. Still A+
• Video
OK video, not as detailed as the 1944 one.
The background music was from Kim Nalley and the "New Orleans Hop Scop Blues" which is by Jimmy Noone.
The theme song is by Kim Nalley and is a cover of "Electricity Electricity" from Schoolhouse Rock :)
