TBWA-Chiat-Day to Handle iPhone Ad Campaign
People familiar with the account confirm that TBWA's Media Arts Lab will handle all creative for the iPhone, much as the agency has for iPod. The agency has handled creative duties for Apple since 1997.
TBWA/Chiat/Day also produced the Apple iPhone teaser advertisement that aired during the Oscars.
There had reportedly been some speculation that AT&T's agency (BBDO) might handle part of the account. AT&T had indicated that they would use the iPhone as a branding and marketing event.
