Whatever your opinion of the relationship between Burger King and Crispin Porter + Bogusky—and their abrupt break-up late last week—it's hard to deny that their work together helped usher in a new era of advertising. From the iconic Subservient Chicken campaign of 2005 to the surreal Adult Swim/frat-boy humor of day-to-day BK advertising, CP+B brought bizarreness and balls-out experimentation into mainstream marketing. Unfortunately, the approach never quite proved its worth, as BK continued to drift further behind McDonald's in market share and revenue growth. A split was inevitable, but a bit regrettable. Today, AdFreak celebrates seven years of CP+B and Burger King with a list of the 15 campaigns we're still talking about, for better or worse. The King is dead. Long live the King.
