IndyCar Series
The IRL was unable to utilize the name IndyCar until the beginning of the 2003 for legal reasons. For 1996-1997, the series was simply called the USAC Indy Racing League. For 1998-1999, the series received its first title sponsor, and was known as the Pep Boys Indy Racing League. In 2000, the series sponsor became the Internet search engine Northern Light. The series was named the Indy Racing Northern Light Series. This only lasted two of the planed five year contract.
