Box Office Mojo

Box Office Mojo is a website that tracks box office revenue in a systematic, algorithmic way. Brandon Gray started the site in 1999. In 2002, Gray partnered with Sean Saulsbury and they grew the site to nearly two million readers when, in July 2008, the company was purchased by Amazon.com through its subsidiary, the Internet Movie Database.

The forums were a popular place for box office "fanatics" and the site at one time was home to several popular movie games and quizzes/test,(e.g., Fantasy Box Office (created in 2006) and Create A Year of Movies), until these were summarily cancelled for financial reasons. Tracking is still done very closely to the day by day, actual tabulation of distributors, making it possible to see the general trend of a film's "earnings trajectory".
