21st Century Fox

In June 2014, 21st Century Fox made a bid to acquire Time Warner, which had similarly spun off its publishing assets, for $80 billion in a cash and stock deal. The deal, which was rejected by Time Warner's board of directors in July 2014, would have also involved the sale of CNN to ease antitrust issues. On August 5, 2014, 21st Century Fox announced it had withdrawn its bid for Time Warner. The company's stock had fallen sharply since the bid was announced, prompting directors to announce 21st Century Fox would buy back $6 billion of its shares over the following 12 months.

On July 25, 2014, 21st Century Fox announced the sale of Sky Italia and Sky Deutschland to BSkyB for $9 billion, subject to regulatory and shareholder approval. Fox would use the money from the sale, along with $25 billion it received from Goldman Sachs, to attempt another bid for Time Warner.

In December 2014, Fox-owned television studio Shine Group merged with Apollo Global Management's Endemol and Core Media Group to form Endemol Shine Group, which was jointly owned by 21st Century Fox and Apollo.

On July 1, 2015, Lachlan Murdoch was elevated to Co-Executive Chairman alongside his father and James Murdoch replaced his father as CEO of the company. Former COO Chase Carey became Executive Vice-chairman.

On September 9, 2015, 21st Century Fox announced a for-profit joint venture with the National Geographic Society, which called National Geographic Partners, which took ownership of all of National Geographic media and consumer businesses, including National Geographic magazine, and the National Geographic-branded television channels that were already run as a joint venture with Fox. 21st Century Fox holds a 73% stake in the company.

On December 9, 2016, 21st Century Fox announced it had made an offer to acquire the 61% share of Sky plc that it did not already own. The company was valued at £18.5 billion. The deal was approved by the European Commission on April 7, 2017, followed by Ireland's Minister for Communications, Climate Action and Environment on June 27. However, the deal has become subject to scrutiny and an extended regulatory review in the United Kingdom, over concerns surrounding the plurality of British news media that will be owned by the Murdoch family post-merger (counting Sky News, as well as News Corp's newspapers and recent acquisition of radio station operator Wireless Group), and violations of British news broadcasting regulations connected to Sky's former carriage of Fox News Channel in the country. However, a bidding war ensued over the company; in September 2018, Comcast won a regulator-mandated auction with a bid of £17.28 per-share. On September 26, 2018, 21st Century Fox subsequently announced its intent to sell all of its shares in Sky plc to Comcast for £12 billion. On October 4, 2018, 21st Century Fox completed the sale of its stake to Comcast, giving the latter a 76.8% controlling stake.

The Kingdom Holding Company, owned by Prince Al-Waleed bin Talal, sold its minority stake in 21st Century Fox during the fiscal quarter ending September 2017. It previously held a 6% stake, which had been reduced to around 5% in 2015. The valuation of the shares, or who they were sold to, is unknown; Al-Waleed was the company's largest single shareholder behind the Murdoch family. The sale was reported after Al-Waleed was arrested in early-November 2017 as part of an anti-corruption probe by the Saudi government.

Sale to Disney

On December 14, 2017, after rumors of such a sale that had been circulating since November 6 following a CNBC report, The Walt Disney Company began its acquisition of 21st Century Fox for $52.4 billion after the spin-off of certain businesses, pending regulatory approval. 21st Century Fox president Peter Rice stated that he expected the sale to be completed by mid-2019.

Under the terms of the deal, 21st Century Fox spun off an entity that was initially being referred to as "New Fox", consisting of the Fox Broadcasting Company, Fox News, Fox Business Network, and the national operations of Fox Sports (such as Fox Sports 1, Fox Sports 2, and Big Ten Network, but excluding its regional sports networks), and Disney acquired the remainder of 21st Century Fox. This included key entertainment assets such as the 20th Century Fox film studio and its subsidiaries; a stake in Hulu; the U.S. pay television subsidiaries FX Networks, Fox Sports Networks and National Geographic Partners; and international operations of Fox Networks Group as well as Star India. The acquisition was primarily intended to bolster two over-the-top content endeavors—ESPN+ and Disney+. Disney will lease the 20th Century Fox backlot in Century City, Los Angeles for seven years.

The proposed transaction raised antitrust issues, due to concerns that it could have led to a tangible loss in competition in the film and sports broadcasting industries. Several legal experts and industry analysts expressed the opinion that the transaction was likely to receive regulatory approval, but would be scrutinized by regulators.

In February 2018, the Wall Street Journal reported that Comcast, the owner of NBCUniversal, was considering a counter-offer. Despite initially bidding $60 billion earlier, Fox had rejected Comcast's offer due to the possibility of antitrust concerns. On May 5, 2018, it was reported that Comcast was preparing to make an unsolicited, all-cash counteroffer to acquire the 21st Century Fox's assets Disney has offered to purchase, contingent on the outcome of an antitrust lawsuit AT&T's acquisition of Time Warner. Comcast confirmed on May 23, 2018, that it was "considering, and is in advanced stages of preparing, an offer for the businesses that Fox has agreed to sell to Disney."

A shareholder vote on the sale was scheduled for special shareholder meetings by Fox and Disney on July 10, 2018, at the New York Hilton Midtown and New Amsterdam Theatre respectively, although Fox warned that it might "postpone or adjourn" the meeting if Comcast were to follow through with its intent to make a counter-offer. It was also reported that Disney was preparing an all-cash offer of its own to counter Comcast's bid.

On June 13, 2018, the day after AT&T was given an approval to merge with Time Warner, Comcast officially announced a $65 billion all-cash counter-offer to acquire the 21st Century Fox's assets Disney had offered to purchase. However, on June 20, 2018, Disney agreed to increase its bid to a $71.3 billion cash-and-stock offer. Fox agreed to the new offer.

The proposed purchase was given antitrust approval by the Department of Justice on June 27, 2018, under the condition that Disney divest all of Fox's regional sports networks. The networks could either be divested to third-parties, or retained by "New Fox". On July 19, 2018, Comcast announced it was dropping its bid for Fox in order to focus on its bid for Sky. On July 27, 2018, it was reported that Fox and Disney shareholders had "overwhelmingly" approved the proposed purchase. The acquisition was expected to be completed by late January 2019, after remaining regulatory approvals are granted in China and the European Union.

In October 2018, it was reported that the new, post-merger organizational structure of "New Fox" would be implemented by January 1, 2019, ahead of the closure of the Disney sale (which was still expected to occur within the early of March).

On November 6, 2018, the European Commission approved the sale, pursuant to the divestment of A&E Networks properties in Europe deemed to overlap with those of Fox. At a shareholders' meeting the following week, it was revealed that the new company would simply be known as "Fox". On November 19, 2018, the deal was approved unconditionally by Chinese regulators.

On January 7, 2019, 21st Century Fox filed the registration statement for "New Fox", under the name Fox Corporation, with the U.S. Securities and Exchange Commission. In an SEC filing, Fox stated that it did not intend to bid for its former regional sports networks.

On February 27, 2019, it was reported by Bloomberg that Disney had also planned to divest the international Fox Sports operations in Brazil and Latin America to secure antitrust clearance in Brazil and Mexico, as they both compete with ESPN International properties in their respective regions. On February 27, 2019, the sale was approved by Brazil's Administrative Council for Economic Defense (CADE), with Disney having agreed to the expected divestiture of Fox Sports Latin America. CADE coordinated with regulators in Mexico and Chile in evaluating the transaction. Mexico approved the sale on March 12, 2019, with similar concessions. Clearance in Brazil and Mexico was reported to be the last major hurdles for the sale.

On March 12, 2019, Disney officially announced that the sale would be completed on March 20, 2019. On March 19, 2019, preliminary trading for the new Fox Corporation on the S&P 500 started in preparation for the formal merger that was finalized on the next day. Under the terms of acquisition, Disney would phase out Fox brand usage by 2024.

Lachlan Murdoch, James Murdoch, their sister Elisabeth Murdoch, and half-sister Prudence MacLeod, each benefited by approximately $2 billion as a result of the Disney transaction.
