K. Rupert Murchoch is an Australian American business magnate. Murdoch became managing director of Australia's News Limited, inherited from his father Sir Keith Arthur Murdoch in 1952. He is the founder, chairman and CEO of global media holding company News Corporation, the world's second-largest media conglomerate, and its successors News Corp and 21st Century Fox after the conglomerate split on 28 June 2013.
In the 1950s and '60s, he acquired various newspapers in Australia and New Zealand, before expanding into the United Kingdom in 1969, taking over the News of the World followed closely by The Sun. He moved to New York City in 1974 to expand into the U.S. market, but retained interests in Australia and Britain. In 1981, he bought The Times, his first British broadsheet, and became a naturalised U.S. citizen in 1985 to satisfy the legal requirement for U.S. television ownership.
In 1986, keen to adopt newer electronic publishing technologies, he consolidated his UK printing operations in Wapping, causing bitter industrial disputes. His News Corporation acquired Twentieth Century Fox (1985), HarperCollins (1989) and The Wall Street Journal (2007). He formed the British broadcaster BSkyB in 1990, and during the 1990s expanded into Asian networks and South American television. By 2000, Murdoch's News Corporation owned over 800 companies in more than 50 countries with a net worth of over $5 billion.
