"NASCAR in Primetime" Premieres Wednesday, Aug. 15 at 10/9c: Stock car racing has its origins in Prohibition-era bootlegging and until recent years was popular mainly with Southern white men. Today, NASCAR casts a far wider net. NASCAR is a multibillion-dollar empire built on brilliant marketing, speed and the American dream. It already has a firm hold on the hearts and minds of Americans and now it's fixing its eye on the rest of the world. NASCAR in Primetime is the first time that NASCAR has given any news organization uncensored access to its inner workings. ABC News spent six months following drivers, fans and officials, documenting everything that happened on and off the racetrack. Our cameras saw people and places that NASCAR has never before allowed to be filmed for TV. For the first time, viewers will get an inside look at the real world of NASCAR. The show will air the next five Wednesday's, starting August 15th [thru Sept 12th], at 10:00pm/et on ABC. (ABC)
