Desert Island Discs is a radio programme broadcast on BBC Radio 4. It was first broadcast on the BBC Forces Programme on 29 January 1942.
Each week a guest, called a "castaway" during the programme, is asked to choose eight audio recordings (usually, but not always, music), a book and a luxury item that they would like to take if they were to be cast away on a desert island, whilst discussing their life and the reasons for their choices. It was devised and originally presented by Roy Plomley, then presented by Michael Parkinson, Sue Lawley, Kirsty Young and Lauren Laverne (more detail later and in the box on the right).
More than 3,400 episodes have been recorded, with some guests having appeared more than once and some episodes featuring more than one guest.
