To celebrate the Oscars, YouTube Ads Leaderboard ranks the best picture nominees based on their trailer’s YouTube views. On YouTube, movie trailers are used to determine whether a movie is worth watching. 78% of YouTube users agree that watching a trailer helps them decide what movies to watch. Even more compelling, this year we noticed that a film’s box office success is positively correlated to the number of views the trailer has on YouTube. The leader of the views rank, happens to also be the leader of earnings at the box office. It’s easy to understand why, given that almost half of YouTube Entertainment users won’t buy a ticket unless they’ve watched the trailer.
