The first radio service in Scotland was launched by the British Broadcasting Company on 6 March 1923. Named 5SC and located in Bath Street in Glasgow, the services gradually expanded to include the new stations 2BD, 2DE and 2EH, based at Aberdeen, Dundee and Edinburgh respectively. Around 1927, the new Corporation, as the BBC now was, decided to combine these local stations into regions under the generic banner of the BBC Regional Programme. Regional programmes throughout the UK were merged to form the BBC Home Service in 1939, and, with a break for the Second World War, national opt outs remained on the station and its successor BBC Radio 4 until the establishment of a separate BBC Radio Scotland in November 1978.
