In 1932, comic book artists Joe Schuster and Jerry Siegel created the Superman character. For six long years during the Great Depression the two tried to market their comic book hero, but no one was interested. Then in 1938, editor Vin Sullivan chose it as the cover feature for National's Action Comics. The following year, Siegel & Schuster initiated the syndicated Superman comic strip. As part of the deal which saw Superman published in National Action Comics, Siegel and Schuster sold the rights to the company in return for $130 and a contract to supply the publisher with material for ten years.
