Welcome to Wikipedia's portal for Radio.
Radio is the wireless transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light.
Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. It does not require a medium of transport. Information is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude or their frequency. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.
The word 'radio' is used to describe this phenomenon, and television, radio, and cell phone transmissions are all classed as radio frequency emissions.
Before the advent of television, commercial radio broadcasts included not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment. Radio was unique among dramatic presentation in that it used only sound.
The Hitchhiker's Guide to the Galaxy is a science fiction comedy radio series written by Douglas Adams (with some material in the first series provided by John Lloyd).[1] It was originally broadcast in the United Kingdom by the BBC, and was soon afterwards broadcast on global short wave radio on the BBC World Service, in 1978. Broadcasting by National Public Radio (one of their first to occur in stereo) in the United States followed in March, 1981, with a repeat broadcast in September.[2] The following year, 1982, the BBC series was carried by CBC Radio (Canadian Broadcasting Corporation).
A pilot programme was commissioned in March 1977, and was recorded by the end of the following June. A second series was commissioned in 1979, and this was transmitted in 1980. Episodes of the first series were specially re-recorded for release on LP records and cassettes. After the 1980 transmissions of the second radio series, the first series was adapted for television; it included some material originally written by Adams for stage adaptations and the aforementioned LP adaptation. This in turn was followed by five novels, a computer game, and adaptations into three series of comic books.
Adams considered writing a third radio series, to be based on his novel Life, the Universe and Everything, in 1993 but the project did not begin for another ten years, after Adams's death. Dirk Maggs, with whom Adams had discussed the new series in 1993, 1997 and 2000, eventually directed and co-produced radio series adaptations of that novel, as well as So Long, and Thanks for All the Fish and Mostly Harmless.[3] These became the third, fourth and fifth radio series. The third series was recorded in 2003 and transmitted in September and October 2004, and the fourth and fifth series were recorded in late 2004 and early 2005 and transmitted in May and June 2005. Recordings of all five series have been released on audio cassette and compact disc, and the third series was released on DVD in 2006, after being "delayed" more than once.[4][5]

BBC Local Radio is the BBC's regional radio service for England and the Channel Islands, consisting of 40 stations. Initially, stations had to be co-funded by the BBC and local authorities, which only some Labour-controlled areas proved willing to do. Radio Leicester was the first to launch on 8 November 1967, followed by Sheffield, Merseyside and Nottingham. By the early 1970s, the local authority funding requirement was dropped, and stations spread across the country; many city-based stations later expand their remit to cover an entire county. Today, stations are asked to target their coverage to Dave and Sue, two fictional fifty-five-year-olds.

Fred Allen (born John Florence Sullivan on May 31, 1894 in Cambridge, Massachusetts, died March 17, 1956 in New York City) was an American comedian whose absurdist, pointed radio show (1934–1949) made him one of the most popular and forward-looking humorists in the so-called classic era of American radio.
His best-remembered gag may be his long-running mock feud with friend and fellow comedian Jack Benny. Allen has been considered one of the more accomplished, daring and relevant humorists of his time. A master ad libber, he constantly battled censorship and developed routines the style and substance of which influenced future comic talents. Perhaps more than any of his generation, Fred Allen wielded influence that outlived both his contemporaries and the medium that made him famous.
