Which is where the money comes in. Let’s not forget that racial/sex demographics are not the only thing that matters in cinema. There’s role demographics. Actors, Producers, Directors, Cinematographers, Special effects, Costume, Set design. These are all varied roles within the industry that have different voting interests. Actors might look for the best performers, producers for the highest earnings, set design for the most elaborate sets. It’s easy to piece together. Significantly, the least diverse branch is the Academy Executive Branch which consists of the producers who finance the industry. They also influence who is invited into the academy, thus exerting influence over the voting blocs, of which actors (at 22%) are the largest. The Academy is also subject to lavish campaigns run by nominees, who are not beyond gifts and special screenings for members. Icarus this year was a surprise documentary win, apparently Netflix held an aggressive campaign for it, an unconventional move for the category. Amazon similarly "campaigned aggressively" (NY Times, Oscar Nominations 2018) for The Big Sick for Best Picture, reflecting the increasing activity of online streaming giants within an industry hostile to them. Hollywood and the Academy Awards are still very much based within the box office model.
