Other planned changes to the 91st Oscars (2019) will move forward, including restructuring and shortening the length of the telecast to three hours. To honor all 24 award categories, six to eight categories will be presented live, in the Dolby Theatre, during commercial breaks. The winning moments will then be edited and aired later in the broadcast. Selected categories will be rotated each year. The Academy will collaborate with the show producer(s) to select these categories.
