Mobile order and pay has become table stakes for QSR mobile applications, but Burger King took it to the next level by offering people at McDonald’s the chance to get a 1-cent Whopper.
According to the case study, the stunt drove 1.5 million Burger King app downloads, generated 3.5 billion earned media impressions and a 37-to-1 return on investment.
The campaign earned a Titanium Grand Prix, a Direct Grand Prix, and a Mobile Grand Prix.
