Indy Racing League
The Indy Racing League (IRL), better known as IRL, is an all-oval open-wheel racing circuit in the United States and more recently, Japan. Among the races it sponsors is the Indianapolis 500. IRL began in 1994 and is owned by Hulman and Co. who also own the Indianapolis Motor Speedway. IRL was masterminded in 1994 by Tony George and was created with a break-away group of drivers from CART who had coordinated Indycar racing since 1979.
