Keith Rupert Murdoch (born March 11, 1931, in Melbourne, Australia) is an Australian-born American media mogul, proprietor, and founder of News Corp (formerly News Corporation). He built one of the world's largest media empires through aggressive expansion into tabloids, broadsheets, and broadcasting, inheriting his father's newspaper interests in 1952 and acquiring outlets like The Sun and the New York Post in the UK and US, The Wall Street Journal in the US, and founding Fox News in 1996. He was also the former owner of 20th Century Fox, which held a long-term distribution partnership with Milchan's Regency Enterprises. His career includes bold business strategies such as the 2011 split of News Corp into separate news and entertainment entities. Murdoch stepped down as CEO of Fox Corporation in 2023 and is the former Chairman of Fox Corp; he remains Executive Chairman of News Corp, overseeing assets that reach billions worldwide. He became a US citizen in 1985 to expand his broadcasting interests. His media empire has faced significant controversies including the 2011 News of the World phone-hacking scandal in the UK. Murdoch is known for exerting significant influence on politics and global media, particularly through Fox News in the US, often aligning with conservative causes. With a net worth estimated at US$21.7 billion in 2022, he continues to shape public discourse across continents. He has been a long-term professional and personal rival in the British media market.
