The road to Carlson's success—or that for xerography's success—had been long and filled with failure. He was turned down for funding by more than twenty companies between 1939 and 1944. He tried for some time to sell the invention to International Business Machines (IBM), the great vendor of office equipment, but no one at the company saw merit in the concept—it is not clear that anyone at IBM even 'understood' the concept. His next-to-last attempt to garner the interest—and funds—he needed to commercialize the physics was a meeting with the Department of the Navy. The Navy had a specific interest in the production of dry copies, but they did not "see" what Carlson saw.
