Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates oscillating electrical energy, often characterized as a wave. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications.

In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, and the reflected waves reveal the object's location to a receiver that is typically colocated with the transmitter. In radio navigation systems such as GPS and VOR, a mobile navigation instrument receives radio signals from multiple navigational radio beacons whose position is known, and by precisely measuring the arrival time of the radio waves the receiver can calculate its position on Earth. In wireless radio remote control devices like drones, garage door openers, and keyless entry systems, radio signals transmitted from a controller device control the actions of a remote device.

The Goon Show is a British radio comedy programme, originally produced and broadcast by the BBC Home Service from 1951 to 1960, with occasional repeats on the BBC Light Programme. The first series, broadcast from 28 May to 20 September 1951, was titled Crazy People; subsequent series had the title The Goon Show.

The show's chief creator and main writer was Spike Milligan, who performed the series alongside Harry Secombe, Peter Sellers and (for the first two series) Michael Bentine. The scripts mixed ludicrous plots with surreal humour, puns, catchphrases and an array of bizarre sound effects. There were also light music interludes. Some of the later episodes feature electronic effects devised by the fledgling BBC Radiophonic Workshop, many of which were reused by other shows for decades. Elements of the show satirised contemporary life in 1950s Britain, parodying aspects of show business, commerce, industry, art, politics, diplomacy, the police, the military, education, class structure, literature and film.
