Toyota Prius is known worldwide by its environment-friendly hybrid technology. Promoting this concept, we created an interaction that demonstrates Prius' care for nature and the environment.The idea was to ask the users to think again before printing unnecessary articles from their Internet. We accomplished this by displaying a "reminder message" pop-up banner, just when the user clicks on the "Printable Version" button.The interaction provided a unique brand experience, thus delivering the campaign's message in an engaging way and using the media to help promote Toyota Prius values.
