BBC Birmingham is one of the oldest regional arms of the BBC, located in Birmingham. It was the first region outside London to start broadcasting both the corporation's radio (in 1922) and television (in 1949) transmissions, the latter from the Sutton Coldfield television transmitter. From 1971 BBC Birmingham was based at the Pebble Mill Studios, replacing studios on Broad Street, but in 2004 moved to the Mailbox facility in the city centre. Pebble Mill has been demolished to make way for a dental hospital and school of dentistry, which opened in 2016.
