Created coffee aroma atomizers triggered by the Dunkin’ Donuts jingle sound.

Our targets usually commute to work primarily via public transportation on buses and subways due to traffic congestion in Seoul. So we created a machine that releases a coffee aroma when the Dunkin’ Donuts jingle is heard. The machine is installed in buses and is only triggered by the Dunkin radio ad.

People exposed to this spatial ad are subtly reminded of coffee along with Dunkin, and as a result visit Dunkin’ Donuts shops on their way to work.

1. For 1 month of a pilot test period in 2 Dunkin stores, 3,826 people(26.4% of coffee consumers) used the coupon. And of course, most of them remembered our message perfectly. Sales also increased by 17%.2. People sang out "I'm drinking Dunkin" happily and willingly. Like we'd hoped, through Voice Coupon, our message truly stayed with the consumers and they passed it on.3. In May, Dunkin Donuts is preparing for a nationwide campaign of Voice Coupon season 2, during which consumers will gleefully shout out “Make it cool, Dunkaccino!”
