In 1941 John Hubley left Screen Gems and formed a studio with former Disney animators Stephen Bosustow, David Hilberman, and Zachary Schwartz, who—like Hubley—had left Walt's nest during the animator's strike. The studio Hubley founded was a newer, smaller animation studio that focused on pursuing Hubley's own vision of trying out newer, more abstract and experimental styles of animation. Bosustow, Hilberman, and Schwartz named the new studio as Industrial Film and Poster Service, or IFPS. Artistically, the studio used a style of animation that has come to be known as "limited animation". The first short from the newly formed studio was "Hell-Bent for Election" (directed by Warners veteran Chuck Jones), a cartoon made for the re-election campaign of Franklin D. Roosevelt. Although this new film was a success, it did not break the boundaries that Hubley and his staffers had hoped. It wasn't until the third short, Bobe Cannon's "Brotherhood of Man", that the studio began producing shorts aggressively stylized in contrast to the films of the other studios. Cannon's film even preached a message that, at the time, was looked down upon—racial tolerance. By 1946, the studio was renamed as United Productions of America (UPA), and Hilberman and Schwartz had sold their shares of the studio stock to Bosustow.
