With the Indianapolis 500 just days away, the company that runs the race said things are looking good.
"Attendance this May so far is up 30 percent. The television audience so far is up fivefold over last year and we haven't gotten to the big race yet," said Mark Miles, CEO of Hulman & Co., which owns IndyCar.
The company recently made several changes in an effort to increase its visibility and its bottom line, including adding the IndyCar Grand Prix before the Indy 500. IndyCar has also changed its qualifying format, its series calendar and has added Verizon as a sponsor.
