Warner Bros. Animation (currently known alternatively as Warner Animation Group for theatrically released films) is the animation division of Warner Bros. The studio is closely associated with the Looney Tunes and Merrie Melodies characters, among others. The studio is the successor to "Warner Bros. Cartoons" (formerly Leon Schlesinger Productions), the studio which produced Looney Tunes and Merrie Melodies cartoon shorts from 1933 to 1963, and from 1967 to 1969. Warner reestablished its animation division in 1980 to produce Looney Tunes–related works.
Since 1990, Warner Bros. Animation has primarily focused upon the production of television and feature animation of other properties, notably including those related to Time Warner's DC Comics publications and some of properties of their Hanna-Barbera division since 2000.
Warner Bros. Animation was one half alongside Amblin Entertainment's television division, "Amblin Television", that were a part of creating Animaniacs. They are expected to be a part of making the Animaniacs reboot as well.
