no idea why the Mike, Ken, Buddy or Ned did not refer to the race as the Primestar 500 but the Texas 500. I don’t think they refer to any of the sponsors on the cars either, maybe policy. Not looking to speculate, it’s their decision — UPDATE 1: The broadcast networks require that the title sponsor of the event purchase a few spots on the telecast for the network to use the entitlement. When Primestar pulled out of the CBS telecast, it became the Texas 500. Note that Saturday’s race was called the Coca-Cola 300 on CBS. — UPDATE 2: Saturday’s BellSouth Mobility 320 will be called the “Nashville 320” when it is broadcast nationally by CBS. CBS explains it reason and policies at The Tennessean
