Bikini Beach Girls At The Daytona 500 NASCAR Sprint Cup Series Race Party, Daytona Beach, Florida, United States

Television
The Daytona 500 was the first 500-mile (800 km) auto race to be televised live flag-to-flag on network television when CBS aired it in 1979, continuing to air until 2000. From 2001 to 2006, the race alternated between FOX and NBC under the terms of a six-year, $2.48 billion NASCAR television contract. Starting in 2007, FOX became the exclusive home of the Daytona 500 under the terms of NASCAR's new television package.
A byproduct of both the track's 1998 lighting system and both the 2001 and 2007 television packages has been later start times. The race started at 12:15 pm (EST) from 1979 until 2000. The start time was moved to 2:30 pm (EST) for the convenience of west coast viewers. The 2005 race ended at sunset for the first time in its history, and the 2006 race ended well after sunset. The changing track conditions caused by the onset of darkness in the closing laps force the crew chiefs to predict the critical car setup adjustments needed for their final two pit stops. Since then, all races have ended after dark, with the 2007 race ending in prime time, at 7:07 pm (EST). However, in 2010, the race moved back to a 1:00 pm start time, which should have resulted in it ending in daylight; however, two red flags caused by track surface issues led to long delays that pushed the race to 7:34 PM EST, pushing the race into prime-time for the second time.
