The Week: Creative Reviews - United in IOC win

WPP's United network has bounced back from the closure of its London office by picking up the global creative account for the International Olympic Committee. The agency triumphed following a pitch against Havas Sport, Leo Burnett and the incumbent, Saatchi & Saatchi, and will work on a global integrated campaign that will launch before next year's Olympic Games, which will be held in Beijing.
