Attendance at the track, however, was perhaps the lowest in the race's 20-year history. That was not necessarily a surprise. What was a little surprising were the details behind the ratings.
The market with the largest rating - where the most people had their TVs tuned to the Brickyard 400 on Sunday - was Indianapolis, with a whopping 13.7 rating. And that was up 26 percent from last year's 10.9 rating.
What that means is a very large segment of residents in the Indianapolis TV market remain firmly loyal NASCAR fans. What it also means is they were not interested in attending the race in person.
That is the best evidence I've seen of the growing disconnect between fans who attend NASCAR races in person and those who remain at home and watch on TV.
It's a gulf NASCAR and the tracks are going to have to work hard to bridge.
