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

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.
The television ratings for the Daytona 500 have surpassed those of the larger Indianapolis 500 (which has much larger physical attendance and international attendance) since 1995, even though the 1995 race was available in far fewer homes than the year before. Then-broadcaster CBS had lost well-established VHF (channels 2–13) affiliates in major markets as a result of the Fox affiliate switches of 1994. As an example, new affiliates WDJT in Milwaukee and WGNX in Atlanta — both cities that are home to NASCAR races — and WWJ in Detroit, close to Michigan International Speedway, were on the UHF band (channels 14–69), meaning that they had a significantly reduced broadcast area compared to former affiliates WITI, WAGA-TV, and WJBK, respectively. WDJT was not available in many Wisconsin markets by the time the Daytona 500 took place.
