A radio program, radio programme, 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.
In the 1950s, a small but growing cohort of rock and pop music fans, dissatisfied with the BBC's output, would listen to Radio Luxembourg – but only to some extent and probably not enough to have any impact on the BBC's monopoly; and invariably only at night, when the signal from Luxembourg could be received more easily. During the post-1964 period, offshore radio broadcasting from ships at anchor or abandoned forts (such as Radio Caroline) helped to supply the demand in western Europe for pop and rock music. The BBC launched its own pop music station, BBC Radio 1, in 1967.
International broadcasts became highly popular in major world languages. Of particular impact were programmes by the BBC World Service, Voice of America, Radio Moscow, China Radio International, Radio France Internationale, Deutsche Welle, Radio Free Europe/Radio Liberty, Vatican Radio and Trans World Radio.
