TBWA\Chiat\Day Los Angeles promoted Stephen Butler to chief creative officer. Butler joined the agency in July 2013 and was promoted following the departure of John Norman in March 2014. As part of the restructure of the Los Angeles creative department, Fabio Costa and Brent Anderson have both been promoted to executive creative directors, reporting to Butler. Butler joined TBWA in July 2013 as executive creative director from Mother London.

In the first year, he and his team handled projects for Unilever, Gucci, P&G Prestige, Elton John AIDS Foundation and the British Government. In 2006, a year after joining Mother, Stephen was asked by U2's Bono to help develop the RED project. Butler worked with Bono and RED's partner brands, including Nike, American Express, Apple, Gap and Starbucks, to engage and drive the private sector into raising awareness and funds to help eliminate HIV/AIDS in Africa. Prior to Mother, Butler was creative director at Bartle Bogle Hegarty, where he led creative for Levi's across Europe.
