. The history of radio broadcasting (experimentally around 1906, commercially around 1920) starts with audio (sound) broadcasting services which are broadcast through the air as radio waves from a transmitter to an antenna and, thus, to a receiving device. Stations can be linked in radio networks to broadcast common programming, either in syndication or simulcast or both.
