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.
