The World: New York - Nike moves $50m Nike+ business back to W&K

Nike has ended its relationship with Crispin Porter & Bogusky after little more than a year.

The sportswear giant confirmed it was moving its running shoe, Nike+ running shoe and Nike ID website business, worth an estimated $50 million, back to its lead agency, Wieden & Kennedy.

Jeff Hicks, the Crispin Porter chief executive, said it had been a mutual decision by the agency and client to go their separate ways.

Nike stunned the agency world in April last year by adding Crispin Porter to an agency roster long dominated by W&K. The move was thought to spell trouble for the lead shop, but the relationship with Crispin Porter resulted in only a single TV ad, for the iPod-integrated Nike+, which ran in December.
