TriStar Pictures is a division of Sony and a sister company of Columbia Pictures. Founded in 1982 as Nova Pictures by a joint venture of Columbia, CBS and HBO, the company's name changed to Tri-Star Pictures and began distributing films in 1984 (their first release was Where The Boys Are '84, a pickup from ITC). Over the next three years Columbia would buy CBS and HBO's shares of the company and finally in 1987, Columbia had taken over the whole company. Throughout its first 15 years, TriStar served as an equal to Columbia by producing similar product while also distributing the films of Carolco Pictures (an arrangement that lasted until 1994, when they switched to Metro Goldwyn Mayer, who distributed most of the studio's final films). After the flop of Godzilla, Sony decided to downscale TriStar and put more emphasis on its then-new B-movie division, Screen Gems.

Today TriStar exists as a division for titles acquired from different companies and the occasional Direct to Video product, but still manages to get a successful film every once in a while (such as District 9).

Also known for its Pegasus mascot and their fanfare, the present version of which was composed by Academy Award winner Dave Grusin.
