The BBC, founded in 1922, is the UK's publicly funded radio, television and Internet broadcasting corporation, and is the oldest and largest broadcaster in the world. It operates numerous television and radio stations in the UK and abroad and its domestic services are funded by the television licence. Other major players in the UK media include ITV plc, which operates 11 of the 15 regional television broadcasters that make up the ITV Network, and News Corporation, which owns a number of national newspapers through News International such as the most popular tabloid ''The Sun'' and the longest-established daily "broadsheet" ''The Times'', as well as holding a large stake in satellite broadcaster British Sky Broadcasting until 2018. London dominates the media sector in the UK: national newspapers and television and radio are largely based there, although Manchester is also a significant national media centre. Edinburgh and Glasgow, and Cardiff, are important centres of newspaper and broadcasting production in Scotland and Wales, respectively. The UK publishing sector, including books, directories and databases, journals, magazines and business media, newspapers and news agencies, has a combined turnover of around £20 billion and employs around 167,000 people.
