The British Broadcasting Corporation is a British public service broadcaster. Its headquarters are at Broadcasting House in Westminster, London.

The BBC is established under a Royal Charter and operates under its Agreement with the Secretary of State for Digital, Culture, Media and Sport. 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 or record live television broadcasts and iPlayer catch-up. The fee is set by the British Government, agreed by Parliament, and used to fund the BBC's radio, TV, and online services covering the nations and regions of the UK. Since 1 April 2014, it has also funded the BBC World Service, which broadcasts in 28 languages and provides comprehensive TV, radio, and online services in Arabic and Persian.
