Carroll Shelby International was formed in 2003 from custom performance vehicle manufacturer Shelby American, when founder and owner Carroll Shelby took the company public, and additionally forming Shelby Automobiles as a subsidiary from which to continue manufacturing vehicles and parts. In 2009, "Shelby Automobiles" was officially renamed to "Shelby American", bringing back the original company name to celebrate the 45th anniversary of the 427 Cobra and GT350. Carroll Shelby Licensing is the second wholly owned subsidiary that forms Carroll Shelby International, which is based in Nevada. Shelby American manufactures component automobiles, including replicas of the small-block and large-block AC Cobras, the Shelby GT350 and the GT500 Super Snake. Since 2005, Shelby American has released new models each year.
