Columbia TriStar Television, Inc. (abbreviated as CTT) was an American television production and distribution company that was active for eight years from 1994 to 2002. It was formed in 1994, by the merger of Columbia Pictures Television and TriStar Television. It was operated as the third name of the early television studio Screen Gems and the fourth name of Pioneer Telefilms, both part of Sony Pictures Entertainment and the third company to use the Columbia and TriStar names together (the first being Columbia TriStar Home Video, now Sony Pictures Home Entertainment and the second, Columbia TriStar International Television). Its flagship work was the preschool television series Harold and the Purple Crayon for HBO Family.
On September 16, 2002, Sony Pictures Entertainment retired the "Columbia TriStar" name from television and renamed the American studio as Sony Pictures Television and its international division as Sony Pictures Television International. Some shows continued using the CTDT name, although many stopped using it in November 2002, while Hollywood Squares continued using it until early 2003. It is still shown on some reruns today even when other episodes use the updated Sony logo.
