Japan loves fried chicken. But they weren't washing it down with Coke.
Then we found something hiding in plain sound: the fizz of Coca-Cola and the sizzle of frying chicken are identical. So we made a viral game out of it - Sizz or Fizz. Skip to the case study.
Each day for a week, we posted a new sound and challenged people to guess: sizz or fizz? People who guessed right won a Coke.
DOOH joined in, playing each day's sound - live.
