(written from a Production point of view)
CBS Television Studios (formerly CBS Studios – original – , Paramount Television and CBS Paramount Television) is a television production company owned by the CBS Corporation (formerly part of the old Viacom) that currently holds the production rights of any future Star Trek television series.
The studio produces Star Trek: Discovery along with its companion and aftershow series, Star Trek: Short Treks, After Trek, and The Ready Room. On 22 April 2019, production on the new, at the time yet-untitled Picard series began.
Having absorbed Desilu in 1967, Paramount Pictures' television division became the owner of Star Trek. Viacom acquired Paramount in 1994, then acquired the original CBS Corporation in 2000. CBS's studio operations and Paramount's television production arm were consolidated as part of the merger.
The television production company took its current form as the result of the late 2005 decision, formalized on 17 January 2006, to split back up the original Viacom conglomerate into two seperate publicly traded companies, CBS Corporation and a new Viacom. CBS Corporation retained the combined television production division (which continued to include "Paramount" in its name until 2009), including the rights to Star Trek, while Paramount Pictures, which is now purely a feature film studio under the ownership of the new Viacom, was granted a license to make Star Trek feature films. Star Trek: Discovery is the first live-action television series in which Paramount has no involvement.
CBS Television Studios presently also consists of its domestic distribution arm, CBS Television Distribution, and its global distribution arm, CBS Studios International.
