The studio also produced other successful cartoon series such as "The Inspector" and "The Ant and the Aardvark". Meanwhile, Chuck Jones, who had been fired from Warner Bros., moved to MGM to produce thirty-four theatrical "Tom and Jerry" cartoons in late 1963. These cartoons were animated in his distinctive style, but they never quite matched the popularity of the Hanna-Barbera originals of the 1940s and 1950s heyday. However, they were more successful than the Gene Deitch "Tom and Jerry" shorts, which were produced overseas during 1961 and 1962. From 1964 to 1967 DePatie–Freleng produced "Looney Tunes" and "Merrie Melodies" shorts under contract with Warner Bros. These cartoons can be recognized easily because they use the modern abstract WB logos instead of the famous bullseye WB shield concentric circles. The studio also subcontracted 11 Wile E. Coyote and the Road Runner cartoons to Format Films. DePatie–Freleng ceased production of "Looney Tunes" and moved to the San Fernando Valley in 1967 to continue production of their "Pink Panther" cartoons producing the final original theatrical cartoon in 1977. The subsequent Pink Panther shorts 1978-1981 were originally produced for Television and then released into theaters. In 1967, WB would resume production on their own cartoons, before shutting down the theatrical cartoon department altogether in 1969. In 1981, the studio was purchased by Marvel Comics and was renamed Marvel Productions. In 1946 the animation union of the time negotiated a pay increase of 25%, making the cartoons more expensive to produce on a general basis. After the 1948 verdict following the Hollywood Antitrust case, there was no longer a booking guarantee on the theatres for cartoons from any of the studios, making it a more risky business and because of this less resources were invested in the theatrical shorts, causing a gradual decline. By the beginning of the 1950s, the medium of television was beginning to gain more momentum, and the animation industry began to change as a result. At the head of this change were the tandem of William Hanna and Joseph Barbera, the creators of "Tom and Jerry." The new Hanna-Barbera utilized the limited animation style that UPA had pioneered. With this limited animation, Hanna and Barbera created several characters including "Huckleberry Hound", "The Flintstones", "Yogi Bear" and "Top Cat". With television's growing popularity, which included the Saturday morning cartoons, a much more significant decline began in movie-going in the 1960s.
