How Did Humans Invent Radio?

How did humans invent radio? Nobody invented it alone. This is the true story of how invisible radio waves went from a pencil-and-paper equation to the voice coming out of your car speakers, and of the inventors who fought over the credit. In this video: James Clerk Maxwell predicts electromagnetic waves, Heinrich Hertz proves them with a spark, Nikola Tesla, Oliver Lodge, Alexander Popov and Jagadish Chandra Bose build wireless pieces, Guglielmo Marconi sends the letter S across the Atlantic, Reginald Fessenden sends the first voice, Lee de Forest builds the Audion tube, and Edwin Armstrong gives us FM radio. We also cover the Titanic distress call, KDKA in 1920 and the first mass broadcast.
