The earliest radio transmissions were made by Hertz in 1887. See http://en.wikipedia.org/wiki/Heinrich_Hertz.
Later, Marconi was the first to commercialize this phenomenon. http://en.wikipedia.org/wiki/Guglielmo_Marconi
Even later, Armstrong introduced FM transmission for improved resistance to static. http://en.wikipedia.org/wiki/Frequency_modulation
