If Disney and Fox had merged last year, the combined studio’s domestic box office would have equaled $4.5 billion. That number creeps close to a 40% market share, a figure no major studio has ever hit. Book-ended by two Star Wars releases plus its Marvel and Pixar fare, Disney by itself hit an industry stateside record of $3 billion in 2016. Before the studio closes out this year with Star Wars: The Last Jedi, a Disney/Fox combo would already be poised to topple that number.
