Tweet a Coke
ABOUT: 2015, Summer in Brazil. Coca-Cola asked us to explore ways to make people engage with the Share a Coke effort. Coca-Cola teamed up with McDonald's and Twitter to create a virtuous sampling initiative: citing @CocaNoMc profile, people could give 1 free Coke at Mc Donald's to those they cared about. The campaign became one of the most successful samplings in Coca-Cola's history.
