🎯 Edwin Howard Armstrong's most famous invention, FM radio, emerged from his work improving AM radio - which ironically led to a devastating patent battle with RCA. 📻 David Sarnoff began his career as a telegraph operator and famously covered the Titanic disaster, using this publicity to help build RCA into a broadcasting empire. ⚡ Lee de Forest's Audion tube was revolutionary but he didn't fully understand how it worked - he once testified incorrectly about its operation in a patent case. 🏛️ The book inspired a PBS documentary of the same name, narrated by Jason Robards and directed by Ken Burns, which aired in 1992. 📡 Early radio broadcasts were so powerful and unregulated that some stations could be heard across entire continents, leading to the Radio Act of 1927 to control the airwaves.
