We knew teens had a lot of love for the Coca-Cola brand, but they just weren’t choosing Coke as their go-to beverage. So how does a 125-year-old brand regain relevance with teenagers?

We decided to own study time. We’d remind teens that Coke can provide the energy to get through the most sluggish study sessions with a useful app that makes it easy to remember class notes by turning them into catchy tunes. The Crammer Keeper let teens type in their study notes, pick a voice and a beat, and commit their lessons to memory, musically.

Through news feeds and emails, word spread fast. Just four months after launch, over 250,000 teens had visited the Crammer Keeper and 86% of them stuck around to play with the app. 32,362 songs have already been created with over 5,463 shared across social networks.

The Crammer Keeper was retired after a nice long year-and-a-half life. Check out the case study video for the whole story.
