Candidate passages:
In 1994, Granada Group took over LWT, thus acquiring the building.
When ITV franchises were permitted to take one another over in the 1990s (which had previously been restricted), Carlton and Granada, between the two companies, eventually owned all the franchises in England and Wales.
By the time the two companies merged in 2004, all of Carlton’s studios had either been sold, or were surplus to requirement, so were sold soon after.
Although the parent companies merged, and are now one (called ITV plc), Granada Television Ltd still exists as a subsidiary of ITV plc, and owns all ITV plc’s studios (wholly in Leeds and London, and formerly as a joint venture with BBC Studios & Post Production in Manchester).
Today the studios produce the bulk of original ITV Studios’ programmes, but anyone can hire the studios, meaning the studios are often seen on other channels’ programmes. 
Second-party developer is a colloquial term used by gaming enthusiasts and media often used to describe two different types of game development studios:  Independently-owned studios who take development contracts from the platform holders and what they produce will usually be exclusive to that platform.
Studios who are partially or wholly owned by the platform holder (also known as a subsidiary) and what they produce will usually be exclusive to that platform.
In reality, the resulting game is first party (since it is funded by the platform holder who usually owns the resulting IP), but the term helps to distinguish independent studios from those directly owned by the platform holder.
These studios may have exclusive publishing agreements (or other business relationships) with the platform holder, while maintaining independence.
Examples are Insomniac Games (which previously developed games solely for Sony's PlayStation platforms as an independent studio) and Game Freak, (which primarily develops the Nintendo-exclusive Pokémon game series). 
Revue Studios.
Revue Productions (also known as Revue Studios) was founded in 1943 by MCA to produce live radio shows and also produced "Stage Door Canteen" live events for the USO during World War II.
Revue was re-launched as MCA's television production subsidiary in 1950.
The partnership of NBC and Revue extends as far back as September 6, 1950, with the television broadcast of "Armour Theatre," based on radio's "Stars Over Hollywood."
MCA bought the Universal Studios lot in 1958 and was renamed Revue Studios.
Following the acquisition of Decca Records, the then-parent of Universal Pictures, the studio backlot name was changed back to Universal.
In 1964, MCA formed Universal City Studios to merge the Motion Picture and Television arms of both Universal Pictures and Revue Productions, and Revue was officially renamed Universal Television in 1966.
During the early years of television, Revue was responsible for producing and/or distributing many television classics.
The most noteworthy included "Leave It to Beaver," which ran for only one season on CBS before going to ABC from 1958 until 1963.
In addition, Revue also made Alan Hale, Jr.'s "Biff Baker, U.S.A." (1952–1953) and all three of Rod Cameron's syndicated series, "City Detective" (1953–1955), "State Trooper" (1956–1959), and "COronado 9" (1960–1961) and the Bill Williams western series, "The Adventures of Kit Carson" (1951–1955).
It produced "Bachelor Father" (1957-1962), for "Bachelor Productions," Edmond O'Brien's syndicated crime drama "Johnny Midnight," based on a fictitious New York City actor-turned-private detective.
Another of its offerings was the 52-episode "Crusader," the first Brian Keith series, which ran on CBS from 1955-1956.
Also McHale's Navy was produced by Revue from 1962 to 1966.
In December 1958 MCA/Revue purchased Universal Studios's 367 acre backlot to produce television series, then leased it back to Universal for a million dollars a year for a decade.
Revue also produced later seasons of "The Jack Benny Program" for CBS and NBC and in co-operation with Jack Benny's J and M productions "Checkmate", "General Electric Theater" and "Alfred Hitchcock Presents" for CBS, "Studio 57" for DuMont, and westerns such as "Tales of Wells Fargo", "The Restless Gun" and "Laramie" for NBC, as well as "Wagon Train" for NBC and ABC, and the first two seasons of NBC's "The Virginian", based on a film released originally by Paramount Pictures, whose pre-1950 theatrical sound feature film library was sold to MCA in 1957.
"Wagon Train" was the only Revue-produced TV show ever to finish an American television season in first place. 
The station has two studios consisting of two identical broadcast studios (Studios 1 & 2).
The stations music output is controlled by RCS Master Control which allows for extensive automation.
Mixing is through RPL Radionet desks taken from the original Lite FM studios. 
Elstree Studios is a generic term which refers to several film studios and television studios based in or around the towns of Borehamwood and Elstree in Hertfordshire, England.
A number of studios have existed in this area since film production began in 1914.
Some of those studios no longer exist, but several studios still survive today.
They are all owned by different organisations and produce both motion pictures and television programmes.
For example, the BBC has studios in Elstree, named "BBC Elstree Centre", whereas another company, Elstree Studios Limited, owns a separate site known as "Elstree Studios".
As a result confusion often occurs.
