Edwin Howard Armstrong told the Federal Communications Commission in 1935 that FM radio would make AM obsolete. The sound was cleaner. The signal was stronger. The interference was gone. He demonstrated it live, switching between AM and FM, and the difference was so obvious that the FCC commissioner said it was “like lifting a curtain.” They gave FM a narrow slice of spectrum. Then they took it away. Then they gave it a different, incompatible slice, which made every existing FM receiver in America worthless.
RCA did this. David Sarnoff, the head of RCA, had invested hundreds of millions in AM infrastructure. FM threatened that investment. Sarnoff had been Armstrong’s friend — they’d known each other since the 1910s, when Armstrong was a young inventor and Sarnoff was a young radio executive and both of them believed they were building the future of communication. The friendship ended when the future turned out to be FM and Sarnoff’s investment was in AM.
Armstrong spent twenty years in court, suing RCA for patent infringement. RCA’s legal strategy was delay. Delay the trial, delay the discovery, delay the ruling. Delay until Armstrong ran out of money. Delay until the patents expired. Delay until the inventor who’d built the technology died or gave up.
Whether Anyone Listened
They didn’t. The FCC sided with RCA on the spectrum reallocation. The courts delayed. Armstrong’s wife left him — not because of the legal fight, but because the legal fight had consumed everything else. His money was gone. His health was gone. His friendships were gone. The only thing that worked was the radio.
He jumped from the thirteenth floor of his apartment building in Manhattan on January 31, 1954. He was 63. He left a note for his wife: “God help you and have mercy on my soul.”
His widow, Marion, continued the lawsuits. She won. Every single one. RCA settled. The other defendants settled. FM radio became the dominant broadcast medium, exactly as Armstrong had predicted in 1935. The technology he invented is in every car, every home, every phone. The man who invented it jumped out a window because the companies that used it wouldn’t pay him.
What He’d Warn You About Now
Armstrong wouldn’t warn you about technology. He’d warn you about incumbents. About the specific mechanism by which an existing industry protects its investment by suppressing a superior replacement.
The mechanism is always the same: regulatory capture. The incumbent doesn’t need to be right. It needs to control the regulatory body. RCA didn’t argue that FM was inferior to AM. RCA argued that the spectrum should be reorganized — a technical decision that happened to destroy FM’s installed base and benefit AM’s existing infrastructure. The argument was presented as engineering. It was business.
He’d ask you to look at the industries where this is happening now. Where a superior technology exists but doesn’t deploy because the incumbent controls the regulatory environment. He’d say this without bitterness — the bitterness was exhausted by 1954. He’d say it with the precision of an engineer describing a system failure, because that’s what it was. The system worked as designed. The design was the problem.
The Personal Cost
He wasn’t a martyr. He was a man who believed that the quality of an invention should be sufficient defense against its competitors, and who learned, over twenty years, that quality has no relationship to market adoption when the market is controlled by people who’ve invested in the alternative.
He invented three of the foundational technologies of radio: the regenerative circuit, the superheterodyne receiver, and FM broadcasting. The first two made AM radio possible. The third made AM radio obsolete. He was punished for the third because the people who’d profited from the first two didn’t want to start over.
The note he left — “God help you and have mercy on my soul” — is eight words from a man who’d spent twenty years writing legal briefs, patent applications, and technical papers. The brevity was uncharacteristic. The despair was not.
He invented FM radio. The industry that used it destroyed him rather than pay him. His widow won every lawsuit after he died. The radio still works. The system that killed him still works too.
Talk to Edwin Howard Armstrong — he tried to warn them. He’d try to warn you too.
