Coca-Cola on its Facebook page Tuesday debuted a 60-second spot for its Super Bowl "Mirage" campaign that features three groups of characters racing through the desert to get a Coke bottle. Consumers will be able to choose who wins the race by watching video "sabotages" that slow down other teams and unlock other content such as free coupons when they are shared. The 60-second ad will air in the first quarter of the Super Bowl, encouraging voting throughout the game, and the group that wins will determine which ad Coca-Cola shows immediately after the game.
