Coca-Cola enlisted singer Jason Derulo, the first of five celebrities, to design a Tumblr theme that can be shared and used by others on the social platform.
The campaign is intended to deepen Coke's relationship with teenagers by offering relevant content that can install on their Tumblr pages, said Stuart Kronauge, senior vice president, Coca-Cola Trademark Brands
"It's one more reminder of Coke in their lives," she said. "It's almost like a dialogue."
