I love short track racing (Taylor's Version)
I dunno. I keep hearing how generations younger than mine want their sports entertainment delivered in shorter packages. Those two-hour races may be one reason why F1 is increasing in popularity in the US. (It's also doing so without a 'decent U.S. effort'.) If there's increased interest in sports car racing, I don't see how the extended endurance races fit what the young'uns want.
Most of the IMSA races are 2-2.5 hours long. The kids will watch that.
The endurance races are a different thing to try to push, and the networks know it. As of right now, the 24 Hours of Daytona only has three hours of television coverage this year with the rest on Peacock. The 24 Hours of Le Mans doesn't have anything resembling mainstream coverage in the United States. It's shown on some really obscure channel. What's it called now? Velocity? MotorTrend? WB Discovery doesn't even offer the 24 Hours of Le Mans on their primary streaming service.
I think the biggest advantage F1 has over NASCAR, IndyCar and IMSA right now is true commercial-free coverage. I don't think people realize how big of a factor that is. Auto racing is the only sport where you miss the action, and a lot of it with NASCAR, because of commercial breaks.
Commercials in NASCAR races really mess up the flow. When you have three commercial breaks within 10-12 minutes, as Fox likes to do with the Daytona 500, it becomes infuriating because you're missing so much and it legitimately becomes hard to keep up with. Remember the TNT "While We Were Away" Summer Series? I vividly remember Jeff Gluck watching one of those Summer Series broadcasts and tweeting about how NASCAR on TNT was unwatchable because of the amount of commercials.
