> Like the rest of the BBC, the World Service is a Crown corporation of the UK Government. Until 2014, unlike the rest of the corporation, which is funded through a television licence fee, the World Service was funded through a Parliamentary grant-in-aid given by the Foreign and Commonwealth Office. In 2008/9 the BBC World Service received 12.4% of the department's £2.2 billion budget[37][38] and in the financial year 2011/12, the service received £255.2 million from this grant.[39]
