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. For many years, BBC Birmingham was based at the Pebble Mill Studios, but in 2004 moved to the brand-new Mailbox facility in the city centre. Pebble Mill has since been demolished to make way for a science park, however the site is currently empty as of 2013.
