Broadcasting tower in Trondheim, Norway

Radio broadcasting is the transmission of signals, especially audio, to receivers using radio waves over a wide area. Listeners require a broadcast radio receiver to receive these signals. "Terrestrial" broadcasts come from stations on land, and include AM and FM (both analog); and DAB (digital). Audio is also broadcast via satellite in both digital and analog, originating from a satellite in orbit around Earth.
