1935: Electrical engineer and inventor Edwin H. Armstrong announces his development of FM broadcasting. Rather than varying ("modulating") the amplitude of a radio wave to encode an audio signal, the new method varied the frequency. FM enabled the transmission and reception of a wider range of audio frequencies, as well as audio free of static, a common problem in AM radio.
