Columbia Pictures Television
Columbia Pictures Television, Inc. (abbreviated as CPT) was launched on May 6, 1974 by Columbia Pictures as an American television production and distribution studio. It is the second name of the Columbia Pictures television division Screen Gems (SG). For 26 years, the company was active from 1974 until 2001, when it was folded into Columbia TriStar Television (which is currently known as Sony Pictures Television), a merger between Columbia Pictures Television and TriStar Television. A separate entity of CPT continues to exist on paper as an intellectual property holder, and under the moniker CPT Holdings (the initials standing for Columbia Pictures Television) to hold the copyright for the TV show "The Young and the Restless", as well as old incarnations from the company's television library such as "What's Happening!!".
