Star Trek, Behind The Scenes

The original Star Trek series began production under Desilu Productions. With the merger of Desilu into Paramount Pictures, that studio assumed outright ownership of the Star Trek franchise until 2006, after which CBS took ownership of the franchise, though certain aspects (feature film and DVD distribution rights) are still owned by Paramount.
