Integrated interactive agency Definition 6 has launched the Coca-Cola "Happiness Machine" video that ties into its "Open Happiness" global ad campaign. The video was introduced via Coca-Cola's YouTube
channel. The "Happiness Machine" campaign features a Coca-Cola vending machine transformed to deliver small "doses" of happiness for unsuspecting college students, in the form of everything from
flowers and pizza, to 6-foot subs and balloon animals.
