Box Office Mojo is an American-operated website that tracks box-office revenue in a systematic, algorithmic way. The site was founded in 1998 by Brandon Gray, and was bought in 2008 by IMDb, which in turn is owned by Amazon.
History
Brandon Gray began running the site on August 7, 1998, making forecasts of the top-10 highest-grossing films in the United States for the following weekend.[1] To compare his forecasts to the actual results, he started posting the weekend grosses and wrote a regular column with box-office analysis. In 1999, he started to post the Friday daily box-office grosses, sourced from Exhibitor Relations, so that they were publicly available online on Saturdays[2] and posted the Sunday weekend estimates on Sundays.[3] Along with the weekend’s movie grosses, he was publishing the daily newspapers, release schedules and other charts, such as all-time charts, international box office charts, genre charts, and actor and director charts. The site gradually expanded to include weekend charts going back to 1982, grosses for older films, an international section expanded to cover the weekly box office of 50 countries, international release schedules, as well as box office results from up to 107 countries.
