TNT closed out its portion of the NASCAR schedule on Sunday by bombarding viewers with nearly one hour of commercials in a three-hour broadcast, according to numbers posted by the web site Cawsnjaws.com.
Overall, 31.1 percent of the New Hampshire Motor Speedway race broadcast was taken up by commercials. That ties with TNT's Sonoma broadcast for the second-highest number of the season behind TNT's Kentucky broadcast, which was 31.7 percent ads.
Cawsnjaws.com did not post numbers for TNT's first two broadcasts at Pocono and Michigan, but even without the data from those races, it seems TNT was aiming for right around the 31 percent number during its broadcasts this season (with the exception of its "Wide Open" coverage at Daytona). By comparison, FOX's commercial percentage was typically in the low-to-mid 20s in its portion of the season.
According to the Cawsnjaws.com numbers, the average time in between commercial breaks during the New Hampshire race was just over five minutes. So roughly every five minutes during the race, TNT cut away for two or three minutes of ads; on 12 occasions, it was even less than five minutes since the previous break.
