since they were last in the rotation for Super Bowl coverage in the regular contract, ended up with two straight Super Bowls (although they were originally scheduled to broadcast Super Bowl XXVI; CBS instead televised the game as part of a swap with the network). CBS is the only other network to televise two Super Bowls (Super Bowl I and II) in a row. NBC, which had held XXVII (according to the original rotation, NBC would have had XXVI and CBS XXVII, but the NFL allowed the networks to switch the two games in order to allow CBS a significant lead-in to its coverage of the 1992 Winter Olympics), was the only network to bid on XXVIII.
