Accumulating piles and piles of bank statements is an old Brazilian habit.

Several businesses have already tried to convince their customers to get rid of paper and receive online statements. The task was not new. It had been tried so many times that people were tired of the effort.

Our challenge was exactly that: change customers' habits, by talking about an old challenge in a new way.

Our goal: 300,000 people.

Idea: Change. Use paper only when it's really necessary.

And to convince people of this, the idea was to take a back-door approach: for the first time in Brazil, we took an internet success to television. It went viral immediately on electronic media. Our effort was so successful that the clip became the most viewed online commercial in the history of Brazil.

Result: more than 625,000 people changed their paper in for digital statements (remembering our goal was 300,000 people). And for the first time in the history of Itaú, the bank became the most liked and recognized brand in Brazilian television. More than 15,000,000 views on YouTube helped the message get out there (most watched branded piece in the history of YouTube in Brazil).
