McCann-Erickson. McCann introduced the ‘total marketing’ agency concept in 1912. This has led to the marketing services conglomerates that we know today. 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 US ordered Standard Oil Co.'s break-up, soon after McCann became its ad manager in 1911, so he formed HK 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 to become McCann-Erickson.
