What if MGM and 20th Century Fox merged into one company?

On January 14, 1971, it was announced that MGM was in talks with 20th Century Fox for a possible merger. This plan was never implemented. But in our alternate history, we imagine that if this merger was successful, MGM and 20th Century Fox merged into one company.

List of changes
(which in this alternate history Turner Entertainment would not have bought, and Warner Brothers would not have owned the MGM library until 1986 and the WB library until 1950), and in 1998 renamed the film studio MGM-Fox Animation. Many MGM films would not have been canceled. For example, Betty Boop was released in 1994, while Sonic the Hedgehog: Wonders of the World came out in 1997.
 * The merger was to end on June 15, 1971.
 * The combined company will be called MGM-Fox Media (1971-1980) and News Corporation (1980-2019).
 * MGM-Fox Media will not sell MGM Records to PolyGram.
 * MGM Records and 20th Century Fox Records will merge to form MGM-Fox Records.
 * MGM Grand Hotel and Casino would become MGM-Fox Grand Hotel and Casino, which would not have been sold by Bally Manufacturing and renamed Bally's Las Vegas (but later Disney, after buying MGM-Fox Media, would have sold MGM-Fox Grand Hotel and Casino)
 * As a result of the merger, MGM-Fox Media will acquire many film studios.
 * Their first purchase after the merger will be RKO General (together with the RKO Pictures movie library).
 * They would then buy Columbia Pictures in 1980 (which in this alternate history would not have bought Coca Cola in 1982 and Sony in 1989) and United Artists. TriStar Pictures would have created it anyway.
 * After that, they would buy Hanna-Barbera and New Line Cinema.
 * They would then buy Marvel in 1989 (and own the entire library of Marvel superheroes), Pathé in 1990, Cannon Films in 1997, and Lucasfilm in 1999.
 * MGM did not file for bankruptcy in 2005 because MGM-Fox Media was very wealthy and was the 3rd largest film studio in the United States after Warner Brothers (2nd place) and Disney (1st place).
 * Fox Kids were called Jetix from the very beginning. The channel would not have been shut down and sold by Disney in 2001 along with Power Rangers, What's with Andy and many other franchises.
 * Disney will only buy Marvel and Lucasfilm together with Fox and MGM.
 * Disney will buy Studio Ghibli in 2006 along with Pixar. In return, MGM-Fox Media / News Corporation will buy Sunrise, Toei Animation, Nippon Animation, TMS Entertainment, and Nihon Ad Systems.
 * In 2013, Disney will buy Sesame Workshop and The Jim Henson Company.
 * Comcast and Apple will compete to buy MGM-Fox Media / News Corporation in addition to Disney.
