S.C. Johnson is consolidating its global communications planning business at PHD, sources said.
The Omnicom Media Group network, already on the company's media roster, takes over from WPP's Maxus, which was appointed as media lead in July 2011. That was when the consumer products giant shifted its creative business to Omnicom's BBDO and WPP's Ogilvy & Mather.
The business is expected to be handled out of PHD, Chicago.
The current change comes after the marketer worked to review and renew agency contracts. In the U.S. alone, S.C. Johnson spends an estimated $300 million on media annually.
An OMG representative declined to comment, referring calls to S.C. Johnson, which could not immediately be reached.
The win further validates PHD's business model which has always been driven more by planning than leveraging media scale. In 2012, PHD won 90 percent of Unilever's plum global communications planning assignments for 16 megabrands, besting other larger shops including Initiative, MPG, Naked, VivaKi and incumbent Mindshare.
