For decades, the Academy of Motion Pictures Arts and Sciences have used choice voting to select Oscar nominees. The process has long been seen as a fair way of representing the breadth of quality films released in a given year, while allowing underdog films to have a chance at winning awards. Choice voting, a proportional voting method, is used for governmental elections around the world, but proportional voting is also widely used in non-governmental elections.
