TriStar Pictures
TriStar Pictures was created in 1982 and founded as Nova Pictures by Victor Kaufman, a high-ranking employee at Columbia. He convinced Columbia, CBS, and HBO to give him money for a new studio, and the first movie made by TriStar was The Natural in 1984. After making several successful movies such as the Rambo series, TriStar was eventually combined with Columbia, which in turn was bought by Sony. Despite taking a backseat to Columbia in the present day, TriStar still makes movies once in a while either through TriStar Productions or by releasing movies from other Sony departments.
