John Seifert, Chairman and CEO of Ogilvy North America was asked by the ANA (Association of National Advertisers) in November 2010 to speak with its members about how they can get the most from their advertising agencies. John Seifert’s presentation was built around 15 central ideas of client/agency relationships that David Ogilvy put forth in his best-selling book “Confessions of an Advertising Man.” The conceits are as vital today as they were when the book was published in 1963.
