One day Siegel and Shuster heard that the editor of Detective Comics was looking for an action series to kick off his new magazine, Action Comics. Eagerly, they presented Superman to the editor. The editor took one long look at the cover drawing, showing Superman lifting a car above his head, and said, "Nobody's going to believe this!" Still, something about the character appealed to the editor, and Siegel and Shuster were offered $130 for all rights to Superman, forever.
At that time, $130 was a lot of money, when a loaf of bread cost 15 cents and the movies a dime. The boys were thrilled when they signed the contract but they would regret this decision for the rest of their lives.
Superman was an instant success. The first issues of Action sold out. Something about the character appealed to everybody, and the public began clamoring for more, more, and still more. Superman got a magazine all his own, then a radio series, an animated cartoon series, newspaper strip, and a movie serial. Siegel and Shuster had to hire assistants to keep up with the work load. The comics company, now called DC Comics, was making millions.
Siegel and Shuster realized they had sold the rights to a gold mine. Time and again they sued the comics company, demanding a cut of the growing Superman empire. Several times they did get more money; by 1940 one magazine reported they were making $75,000 a year. But they never received the percentage they wanted.
