BBC Radio 4

BBC Radio 4 is a British national radio station owned and operated by the BBC. It broadcasts a wide variety of spoken-word programmes, including news, drama, comedy, science and history from the BBC’s headquarters at Broadcasting House, London. It replaced the BBC Home Service in 1967. The station controller is Mohit Bakaya.

Radio 4 broadcasts throughout the United Kingdom, the Isle of Man and the Channel Islands on FM, LW and DAB, and on BBC Sounds. It can be received in the eastern counties of Ireland, northern France and Northern Europe. It is also available on Freeview, Sky, and Virgin Media.

Radio 4 broadcasts news programmes such as Today and The World at One, heralded on air by the Greenwich Time Signal pips or the chimes of Big Ben. The pips are only accurate on FM, LW, and MW; there is a delay on digital radio of three to five seconds and online up to twenty-three seconds. Radio 4 broadcasts the Shipping Forecast which, in August 2017, was 150 years old.
