From 2001 to 2006, the Daytona 500 broadcasting network alternated between Fox and NBC under the terms of a six-year, $2.48 billion, centralized NASCAR television contract. Previously, television rights deals for races were negotiated by the individual track owners. Beginning in 2001, the television contract would now be administered by the sanctioning body. Fox carried the Daytona 500 in odd-numbered years (2001, 2003, 2005), and NBC carried the Daytona 500 in even-numbered years (2002, 2004, 2006). The Pepsi 400 in July followed the opposite pattern, going to the network not airing the Daytona 500 in the respective season.
