Coca-Cola pulls a Facebook and cryptically focuses on the lowly piece of furniture known as a chair in this majestic ad from Publicis Spain and directed by Agosto's Nacho Gayan. A young man who is toiling in the office late at night is brought into the powerful inner sanctum of the four-legged beings that have been controlling us with their plushy offerings for years--until he asks a simple question that topples their power structure forever. The ad is the latest example of the soft drink giant's attempt to address obesity issues.
