One "Bigger is Better" and one "Less is More" commercial will advance to the live vote during the broadcast, when viewers will decide the outcome, and the winner will be revealed at the end of the show.
Of course, that won't be true for viewers in Utah … because the voting will be over before the special airs in this time zone.
