The IndyCar Series, currently known as the NTT IndyCar Series under sponsorship, is the highest class of regional North American open-wheel single-seater formula racing cars in the United States, which has been conducted under the auspices of various sanctioning bodies since 1920 after two initial attempts in 1905 and 1916. The series is self-sanctioned by its parent company, INDYCAR, LLC., which began in 1996 as the Indy Racing League (IRL) and was created by then Indianapolis Motor Speedway owner Tony George as a competitor to Championship Auto Racing Teams (CART). In 2008, the IndyCar Series merged with CART's successor, the Champ Car World Series and the history and statistics of both series, as well as those from its predecessors, were unified. The series' premier event is the Indianapolis 500, which was first held in 1911.
