That "Advocate Marketing" company has a list of customers in the slider banner on their website: Target, AT&T, Fossil, Dole Food Company, McDonalds, Bing, Verizon, UnitedWay (non-profit?!), 3M, Anheuser-Busch, The Clorox Company, Walmart, EMC Corporation, Aveda Corporation, Expedia, Windows Phone, Citibank, Purina, Wells Fargo, Snapfish, Clinique, Oral-B, Sara Lee, Haier. (IT companies/brands are italicized.)
