Radio program

A radio program (radio programme in the United Kingdom) or radio show is a segment of content intended for broadcast on radio. It may be a one-time production or part of a periodically recurring series. A single program in a series is called an episode.

International radio

In Britain, radio broadcasting was dominated entirely by the BBC, which since the early 1920s had been developing a broad spectrum of programming including different genres of music and speech, including documentaries, drama, comedy, news, religious broadcasts, children's programmes, schools broadcasts and sports coverage). BBC output was a unifying force within British culture, and has been written about extensively elsewhere.

In the 1950s, a small but growing cohort of Rock and pop music fans, dissatisfied with the BBC's output, might listen to Radio Luxembourg, but to too small an extent to have any impact on the BBC's monopoly and invariably only at night, when the signal from Luxembourg was stronger. During the post-1964 period, western Europe offshore radio (such as Radio Caroline broadcasting from ships at anchor or abandoned forts) helped to supply the demand for the pop and rock music. The BBC launched its own pop music station, BBC Radio 1, in 1967.

Glenn Beck

Glenn Lee Beck (born February 10, 1964) is an American television personality and radio host, conservative political commentator, author, television network producer, filmmaker, and entrepreneur. He hosts the Glenn Beck Radio Program, a popular nationally syndicated talk-radio show that airs throughout the United States on Premiere Radio Networks and the Glenn Beck television program, which ran from January 2006 to October 2008 on HLN, from January 2009 to June 2011 on the Fox News Channel and currently airs on TheBlaze. Beck has authored six New York Times–bestselling books. Beck is the founder and CEO of Mercury Radio Arts, a multimedia production company through which he produces content for radio, television, publishing, the stage, and the Internet. It was announced on April 6, 2011, that Beck would "transition off of his daily program" on Fox News later in the year but would team with Fox to "produce a slate of projects for Fox News Channel and Fox News' digital properties". Beck's last daily show on the network was June 30, 2011. In 2012, The Hollywood Reporter named Beck on its Digital Power Fifty list.

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.
