From wiki: The Warner Bros. Studio Store was a chain of retail stores selling Looney Tunes and other merchandise based on Warner Bros. films, similar in style to The Disney Store. They first opened in 1991.
In 1996, Warner Bros. owner Time Warner merged with Turner Broadcasting, which owned Hanna-Barbera and the pre-1986 MGM library, and merchandise based on Turner properties were added to the product lines.
In 2001, all Warner Bros. Studio Stores went out of business.
