Columbia Tristar Home Video is an American film production/distribution studio and subsidiary of Sony Pictures Entertainment, owned by the Sony Corporation of Japan.
Originally Tri-Star Pictures, Inc., on December 21, 1987, Tri-Star Pictures, Inc. was renamed to Columbia Pictures Entertainment, Inc. when Coke sold its entertainment business to Tri-Star for $3.1 billion, also creating Columbia/Tri-Star by merging Columbia and Tri-Star.
Both studios continued to produce and distribute films under their separate names.
In 1989, all of Coke's entertainment holdings were acquired by Sony Corporation of Japan, who merged Columbia and Tri-Star, but continued to use the separate labels.
