This is what we found on Wikipedia regarding the BBC Earth Experience - Relaxed Performances:

The British Broadcasting Corporation (BBC) is a British public service broadcaster that serves as the primary national public broadcasting company of the United Kingdom, headquartered at Broadcasting House in London, England. Originally established in 1922 as the British Broadcasting Company, it evolved into its current state with its current name on 1 January 1927. It is the oldest and largest local and global broadcaster by stature and by number of employees, with a total staff of 21,000.

The BBC was established under a royal charter, and operates under an agreement with the secretary of state for 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 or to use the BBC's streaming service, iPlayer. The fee is set by the British government, agreed by Parliament, and is 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 (launched in 1932 as the BBC Empire Service), which broadcasts in 28 languages and provides comprehensive TV, radio, and online services in Arabic and Persian.

Some of the BBC's revenue comes from its commercial subsidiary BBC Studios (formerly BBC Worldwide), which sells BBC programmes and services internationally and also distributes the BBC's international 24-hour English-language news services BBC News, and from BBC.com, provided by BBC Global News Ltd.

Since its formation in 1922, the BBC has played a prominent role in British life and culture. It is sometimes informally referred to as the Beeb or Auntie. In 1923 it launched Radio Times (subtitled "The official organ of the BBC"), the first broadcast listings magazine; the 1988 Christmas edition sold 11 million copies, the biggest-selling edition of any British magazine in history.
