Coca-Cola and Audi are both letting fans select the commercials they air during the Super Bowl with “a choose your own adventure” approach. In “Coke Chase,” viewers get to pick the outcome of a chase scene in real time and can set up obstacles for the opposing teams. Audi on the other hand is airing its ad on YouTube with options for the ending. Fans can vote for their favorite, which will be announced on YouTube and will air on game day as well. These strategies help entertain and engage fans, making them part of the creation process. (USA Today)
