Sony Pictures Television
On September 16, 2002, Sony Pictures Entertainment retired the name "Columbia TriStar" 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.
Sony
Sony entered the television and film production market when it acquired Columbia Pictures Entertainment in 1989 for $3.4 billion. Columbia lives on in the Sony Pictures Motion Picture Group, a division of SPE which in turn owns Columbia Pictures and TriStar Pictures among other film production and distribution companies such as Screen Gems, Sony Pictures Classics, Sony Pictures Home Entertainment. SPE's television division is known as Sony Pictures Television.
For the first several years of its existence, Sony Pictures Entertainment performed poorly, leading many to suspect the company would sell off the division. Sony Pictures Entertainment encountered controversy in the early 2000s. In July 2000, a marketing executive working for Sony Corporation created a fictitious film critic, David Manning, who gave consistently good reviews for releases from Sony subsidiary Columbia Pictures that generally received poor reviews amongst real critics. Sony later pulled the ads, suspended Manning's creator and his supervisor and paid fines to the state of Connecticut and to fans who saw the reviewed films in the US. In 2006 Sony started using ARccOS Protection on some of their film DVDs, but later issued a recall.
