Wonderful interactive campaign by GranataPet pet foods ad agency Agenta, Germany.
The campaign worked by setting up billboards that asked passers by with dogs to “Check In” on Foursquare, once checked in a controlled amount of the dog food was automatically dispensed into a bowl at the bottom of the billboard.
Simple yet effective, they claim 100’s of passers by checked in, and sales of GranatPet increased at local pet shops.
