Last month an unlikely underdog stunned the marketing world at the International Cannes Advertising Festival. At the show, a single marketing campaign took home a Grand Prix award in three categories simultaneously--direct, cyber and PR-- something that had never happened before in the 50+ year history of the show.

Contrary to what you might expect, the unanimous winner of this unprecedented victory was not a Fortune50 brand with an advertising budget of millions, but a small Tourism board promoting a little known island off the Great Barrier Reef.

The winning campaign was called the "Best Job in the World" and was essentially a big online job search conducted through social media for a new "caretaker" for Hamilton Island in Queensland, Australia. Done on a comparatively paltry marketing budget of just $1.7 million dollars and reliant on fortuitous PR and word of mouth, the campaign achieved stunning results, including over 34,000 video entries from applicants in 200 countries, and more than 7 million visitors to the site who generated nearly 500,000 votes.
