The British Broadcasting Corporation (BBC) is a British public service broadcasting statutory corporation. Its main responsibility is to provide impartial public service broadcasting in the United Kingdom, the Channel Islands, and the Isle of Man. The BBC is headquartered at Broadcasting House in London and has major production centres in Salford Quays, Belfast, Birmingham, Bristol, Cardiff and Glasgow, and smaller production centres throughout the UK. The BBC is the world's oldest national broadcasting organisation and the largest broadcaster in the world by number of employees, with about 23,000 staff.
The BBC is a public service broadcaster that operates under a Royal Charter and a Licence and Agreement from the Home Secretary. Within the United Kingdom its work is funded principally by an annual television licence fee, which is charged to all British households, companies and organisations using any type of equipment to receive live television broadcasts; the level of the fee is set annually by the British Government and agreed by Parliament.
