in 1935, twentieth century pictures, inc. and fox film corporation merged together to form "twentieth century-fox film corporation" (the hyphen between "century" and "fox" was dropped in 1985), or simply "20th century fox". during the golden age of hollywood it was one of the "big five" studios (the other were mgm, paramount pictures, rko radio pictures and warner bros. pictures). from 2013-2019, it was a subsidiary of 21st century fox inc., which was a company formed when news corporation split up into two companies. as of july 2018, their two most financially successful films are "avatar", released in 2009, and "titanic" (under international rights), released in 1997. both films were directed by james cameron. fox's most highly acclaimed film, according to review aggregator website rotten tomatoes (jointly owned by universal and warner bros.), is "all about eve", released in 1950 and directed by joseph l. mankiewicz. in december 2017, disney announced its plans to buy most of 21st century fox's assets, which included a bidding war with comcast; the acquisition process was completed on march 20, 2019, with the last pre-disney release from the studio being "alita: battle angel", released on february 14, 2019. the remaining assets disney didn't acquire, notably the fox network and fox news, were spun-off into a new company called fox corporation. on january 17, 2020, disney announced that it would be dropping the word "fox" from the company name, presumably to avoid confusion with fox corporation, renaming it to "twentieth century studios," along with searchlight pictures. however, the studio was still legally incorporated and traded as twentieth century fox film corporation until december 4, 2020. as of december 4, 2020, the company has been using 20th century studios, inc. as copyright for 20th century studios and searchlight pictures, while the company has been using 20th television, inc and 20th centuary fox in australia under gerard bevan group ceo and vp. for the copyright of 20th television productions as a disney subsidiary.
