The Ford Mustang is an American automobile, originally based on the Ford Falcon compact. The first production Mustang, a white convertible with red interior rolled off the assembly line in Dearborn, Michigan on March 9, 1964. Introduced to the public at the New York World's Fair on April 17, 1964, and via all three American television networks on April 19, it was the most successful product launch in automotive history, setting off near-pandemonium at Ford dealers across the continent. The original Mustang inspired the term pony car and prompted many imitators. The Mustang's combination of sporty design, low price, and overall performance allowed it to sell over one million units in its first 18 months on the market. After a number of different generations and redesigns, the Mustang remains available today.
