In Spain Danone is running an integrated campaign to target kids who love football on the way to Germany 2006. They have created a site, danet.es in which users can navigate as if they were walking around a stadium (moving from the bar to the locker room or the press room etc...). Images of Ronaldinho, Danet's testimonial, are everywhere, but the site offers more than just his smiling "bunny" face. It is definitely content rich, and the interface offers a good experience to discover all the goodies available.
As explained on Marketing Directo, mobile is also part of the effort, with branded content available for download.
