British Broadcasting Company

The British Broadcasting Company Limited (BBC) was the commercial forerunner to the public British Broadcasting Corporation and formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom. Licensed by the UK's General Post Office, its original office was located on the second floor of Magnet House, a GEC building in London, and consisted of a room and a small antechamber.
