Dick and Mac McDonald moved to California to seek opportunities they felt unavailable in New England. Failing in the movie business, they subsequently proved successful in operating drive-in restaurants. In 1948 they took a risk by streamlining their operations and introducing their Speedee Service System featuring 15 cent hamburgers. The restaurant’s success led the brothers to begin franchising their concept—nine becoming operating restaurants. At the San Bernardino location, Dick and Mac McDonald perfected their Speedee Service System featuring a limited menu including fifteen cent hamburgers, shakes and fries. The brothers sold 14 franchises of which 10 became operating restaurants not including their original location in San Bernardino.
