Foldgers gorilla marketing

Foldgers turned a seemingly useless advertising location into something innovative and creative. This gorilla marketing technique has led people to repost photos of it all around the web. All of this viral marketing came at no cost to them. Thats a sewer for all of those people who have not been to a city and seen them during the winter. The ad states around the cup of coffee "Hey, City that never sleeps. Wake up!"
