Activities in the United States

Murdoch made his first acquisition in the United States in 1973, when he purchased the San Antonio Express-News. In 1974, Murdoch moved to New York City, to expand into the US market; however, he retained interests in Australia and Britain. Soon afterwards, he founded Star, a supermarket tabloid, and in 1976, he purchased the New York Post. On 4 September 1985, Murdoch became a naturalized citizen to satisfy the legal requirement that only US citizens were permitted to own US television stations.

In March 1984, Marvin Davis sold Marc Rich 's interest in 20th Century Fox to Murdoch for $250 million due to Rich's trade deals with Iran, which were sanctioned by the US at the time. Davis later backed out of a deal with Murdoch to purchase John Kluge 's Metromedia television stations. Rupert Murdoch bought the stations by himself, without Marvin Davis, and later bought out Davis's remaining stake in Fox for $325 million. The six television stations owned by Metromedia formed the nucleus of the Fox Broadcasting Company, founded on 9 October 1986, which later had great success with programs including The Simpsons and The X-Files.

In 1986, Murdoch bought Misty Mountain, a Wallace Neff designed house on Angelo Drive in Beverly Hills. The house was the former residence of Jules C. Stein. Murdoch sold the house to his son James in 2018.

In 1987, Murdoch created his global television special, the World Music Video Awards, a special music ceremony award where winners were chosen by viewers in eight countries. In Australia, during 1987, he bought The Herald and Weekly Times Ltd., the company that his father had once managed.Rupert Murdoch's 20th Century Fox bought out the remaining assets of Four Star Television from Ronald Perelman 's Compact Video in 1996. Most of Four Star Television 's library of programs are controlled by 20th Century Fox Television today. After Murdoch's numerous buyouts during the buyout era of the eighties, News Corporation had built up financial debts of $7 billion (much from Sky TV in the UK), despite the many assets that were held by NewsCorp. The high levels of debt caused Murdoch to sell many of the American magazine interests he had acquired in the mid-1980s.

In 1993, Murdoch's Fox Network took exclusive coverage of the National Football Conference (NFC) of the National Football League (NFL) from CBS and increased programming to seven days a week. In 1995, Fox became the object of scrutiny from the Federal Communications Commission (FCC), when it was alleged that News Ltd.'s Australian base made Murdoch's ownership of Fox illegal. However, the FCC ruled in Murdoch's favour, stating that his ownership of Fox was in the best interests of the public. That same year, Murdoch announced a deal with MCI Communications to develop a major news website and magazine, The Weekly Standard. Also that year, News Corporation launched the Foxtel pay television network in Australia in partnership with Telstra. In 1996, Murdoch decided to enter the cable news market with the Fox News Channel, a 24-hour cable news station. Ratings studies released in 2009 showed that the network was responsible for nine of the top ten programs in the "Cable News" category at that time. Rupert Murdoch and Ted Turner (founder and former owner of CNN) are long-standing rivals. In late 2003, Murdoch acquired a 34% stake in Hughes Electronics, the operator of the largest American satellite TV system, DirecTV, from General Motors for $6 billion (USD). His Fox movie studio had global hits with Titanic and Avatar.

In 2004, Murdoch announced that he was moving News Corporation headquarters from Adelaide, Australia to the United States. Choosing a US domicile was designed to ensure that American fund managers could purchase shares in the company, since many were deciding not to buy shares in non-US companies.

On 20 July 2005, News Corporation bought Intermix Media Inc., which held Myspace, Imagine Games Network and other social networking-themed websites, for US$580 million, making Murdoch a major player in online media concerns. In June 2011, it sold off Myspace for US$35 million. On 11 September 2005, News Corporation announced that it would buy IGN Entertainment for $650 million (USD).

In May 2007, Murdoch made a $5 billion offer to purchase Dow Jones & Company. At the time, the Bancroft family, who had owned Dow Jones & Company for 105 years and controlled 64% of the shares at the time, declined the offer. Later, the Bancroft family confirmed a willingness to consider a sale. Besides Murdoch, the Associated Press reported that supermarket magnate Ron Burkle and Internet entrepreneur Brad Greenspan were among the other interested parties. In 2007, Murdoch acquired Dow Jones & Company, which gave him such publications as The Wall Street Journal, Barron's Magazine, the Far Eastern Economic Review (based in Hong Kong) and SmartMoney.

In June 2014, Murdoch's 21st Century Fox made a bid for Time Warner at $85 per share in stock and cash ($80 billion total) which Time Warner's board of directors turned down in July. Warner's CNN unit would have been sold to ease antitrust issues of the purchase. On 5 August 2014 the company announced it had withdrawn its offer for Time Warner, and said it would spend $6 billion buying back its own shares over the following 12 months.

Murdoch left his post as CEO of 21st Century Fox in 2015 but continued to own the company until it was purchased by Disney in 2019. A number of television broadcasting assets were spun off into the Fox Corporation before the acquisition and are still owned by Murdoch. This includes Fox News, of which Murdoch was acting CEO from 2016 until 2019, following the resignation of Roger Ailes due to accusations of sexual harassment.
