While the Model T dominated the auto industry from 1908 to the early 1920s, by the middle of the decade there was fierce competition from other automakers. After the 15 millionth Model T drove off the assembly line on May 26, 1927, Ford closed plants all over the world to spend six months retooling factories and perfecting the design of a new car. Ford called the new car the Model A, commemorating Ford Motor Company’s first car, the 1903 Model A. The car was the first vehicle to sport the iconic Blue Oval logo, and it included innovative features like a Safety Glass windshield. By 1931 Ford had sold over five million Model As despite the difficulties of the Great Depression.
