Those same deep (greedy) pockets led to Armstrong's suicide over the crap they gave him for his invention of FM. Truly despicable ego driven corporate behavior.

PS The real tragedy and irony of what Sarnoff did to this man is that if he had only embraced the technology then RCA could've made a fortune for themselves by selling new compatible radios and transmitters, just like what we now endure whenever a new recording format appears (Cylinder records-Discs-LP-Wire recording-RTR-4 track-8 track-Cassette-CD-Mini Disc-MP3........1/2" video tape-Beta-VHS-8mm-Digital.....Laser Disc-DVD-who knows what next!)
