BBC Radio 4 Extra (formerly BBC Radio 7) is a British digital radio station owned and operated by the BBC. The sister station of BBC Radio 4, it mostly broadcasts archived repeats of comedy, drama and documentary programmes. It is the principal broadcaster of the BBC's spoken-word archive, and as a result the majority of its programming originates from that archive. It also broadcasts extended and companion programmes to those broadcast on Radio 4, and provides a "catch-up" service for certain programmes.
