Indy Racing League, LLC is an American-based auto racing sanctioning body, adopting the trade name of INDYCAR. INDYCAR sanctions four racing series, the premier IZOD IndyCar Series (often abbreviated ICS or IICS) with its centerpiece Indianapolis 500, and developmental series Firestone Indy Lights, the Star Mazda Championship and the U.S. F2000 National Championship, which are all a part of The Road To Indy. The trade name INDYCAR was officially adopted on January 1, 2011. Indy Racing League, LLC is owned by Hulman and Co., which also owns the Indianapolis Motor Speedway complex and the Clabber Girl brand. The League's premier series was named the Indy Racing League IndyCar Series in 2003. Izod was announced as the IndyCar Series title sponsor in 2010, a deal expected to run for at least five years. The series initially raced exclusively on oval tracks, as the series was founded partly in response to the increasing prominence of road and street courses on the CART schedule.
