The British Broadcasting Corporation (BBC) operates from numerous properties across the United Kingdom and has historically occupied several others. Broadcasting House in London serves as the corporation's headquarters, with numerous other divisions also based in London and various locations throughout the UK. Since 2007, the BBC has been expanding its presence at MediaCityUK in Salford, resulting in the relocation of several departments there. Additionally, the corporation maintains production bases in Belfast, Birmingham, Bristol, Cardiff, and Glasgow. Beyond the UK, the BBC owns news bureaus and relay stations internationally.
