TriStar Pictures
In 1989, Columbia Pictures Entertainment, Inc. was acquired by Sony Corporation of Japan, who merged Columbia and Tri-Star, but continued to use the separate labels. On July 11, 1990, Tri-Star Pictures dissolved and sold its venture in TeleVentures to Stephen J. Cannell Productions and TeleVentures became Cannell Distribution Co. Most of the series and the Tri-Star film packages that were distributed by TeleVentures were transferred to Columbia Pictures Television Distribution. The Tri-Star film packages were transferred to Columbia Pictures Television Distribution. Sony Pictures Entertainment later revived TriStar Television as a television production banner in 1991 and merged with its sister television studio Columbia Pictures Television to form Columbia TriStar Television on February 21, 1994. Both studios continued to operate separately until TriStar folded in 1999 and CPT in 2001.
