Yahoo! te leva a Cannes

Se você for morador de "United States, India, United Kingdom, Hong Kong, Korea, Australia, France, Spain or Italy", vale a pena tentar levar o grande prêmio.

A essência da coisa é:
"Your advertisement must be about a "green" issue. Some examples are Water Preservation and Conservation, Climate Change, Animal Protection, Desertification, and Renewable Energy. No swearing, no naked people, nothing too violent or offensive. Essentially, we’re looking for something smart, original and creative to represent the Yahoo! brand."
