Most expensive billboard advert

A site at the entrance of the Burj Khalifa in Dubai became host to the most expensive billboard ad in June 2012 when energy drinks company Go Fast and the skydiving centre Skydive Dubai combined forces and resources to promote their services with the aid of a man wearing a jet pack. The 30-second stunt, during which Jet Pack Man flew around the billboard, cost an estimated $15,000. According to Skydive Dubai, it would have cost $1.3 billion to maintain the billboard advert for a month.
