Paramount Television

Paramount Television was the television production division of Paramount Pictures, operating from 1967 to 2006. It held the rights to co-produce Doctor Who and its spinoffs between 1998 and 2006.

The "Paramount Deal"
To be added.

The Viacom Split
In 1994, Viacom aquired Paramount, and in 2000 it then acquired CBS Corporation. Paramount Television was dissolved as the result of the late 2005 decision, formalised on 17 January 2006, to split back up the original Viacom conglomerate into two separate publicly traded companies, CBS Corporation and a new Viacom.

CBS Corporation retained the combined television production division, including the rights to Doctor Who, while Paramount Pictures, which is now purely a feature film studio under the ownership of the new Viacom, was granted a license to make Doctor Who feature films.
