Cadbury and Ogilvy Mumbai have come together to create a campaign that takes the 5 Star chocolate bar's classic tagline "Do Nothing" to a whole new level. With ad spend ramping up for the festive season, 5 Star decided to do the opposite, and spend nothing on ads this season. Instead, an easy change to 5 Star's logo helped turn every mobile app in the world into a free advertisement for 5 Star. In that way, #5StarsEverywhere is the biggest ad campaign ever.
