Ogilvy & Mather, which provides PR, advertising and government relations services, has a long list of high-profile clients, including BP, Coca-Cola and Pfizer. The agency has also done extensive work for the American Chemistry Council, which paid the firm more than $15 million in 2008 alone. That year, Ogilvy led a PR campaign that discouraged Americans from supporting a ban on products containing phthalates, a group of chemicals found in plastics and suspected of being a health hazard. The firm earned awards for the phthalates campaign, which it dubbed “From Toxic to Truthful: Turning the Tide on Phthalates.”
