Keith Rupert Murdoch, AC, KSG is an Australian American media mogul. Murdoch became managing director of Australia's News Limited, inherited from his father, in 1952. He is the founder, Chairman and CEO of global media holding company News Corporation, the world's second-largest media conglomerate.
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 in 1974 to expand into the US market, but retained interests in Australia and Britain. In 1981, he bought The Times, his first British broadsheet, and became a naturalised US citizen in 1985.
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, HarperCollins and The Wall Street Journal. He formed 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.
