BoxOfficeMojo.com has vanished with the site redirecting to Amazon.com’s IMDb.

The Box Office Mojo site was acquired by Amazon in late 2008. Reps for Amazon were not immediately available for comment.

The free Box Office Mojo site was widely used by the movie industry for up-to-date box office results along with historical data and release dates of upcoming titles. It was founded in 1999 by Brandon Gray.

When Box Office Mojo was acquired in 2008, it was operated in a Los Angeles office by Gray and Sean Saulsbury.

IMDb provides cursory coverage of box office data, leaving out such information as the specific distributor, the number of theaters and international grosses. Its subscription-based IMDb Pro subscription site has slightly more information.

UPDATE at 7:45 pm PDT Saturday — Without explanation, the Box Office Mojo site returned.
