. Harrison King McCann (1880-1962) H.K. McCann Co. and McCann-Erickson, New York List No. 61 of 100 Go to the Next Person of the Century McCann introduced the "total marketing" concept in 1912 as he led his agency to overseas growth. Enthusiastic about motivational research studies, he took advertising beyond its creative focus and introduced public relations, research library, sales promotion and production survey services. The U.S. ordered Standard Oil Co.'s breakup soon after McCann became its ad manager in 1911, so he formed H.K. McCann the next year to provide ad continuity, and opened overseas offices. In 1930, the Depression led him to merge with Albert Erickson's smaller 17-year-old agency. All Rights Reserved © 1999 & 2005, Advertising Age Crain Communications, Inc. editor@AdAge.com .
