Omnicom was founded in 1986, as a “big bang” merger between three of the largest U.S. advertising agencies – BBDO Worldwide, Doyle Dane Bernbach; and Needham Harper Worldwide. The group has been guided by President-CEO John Wren since 1997, and functions as the parent company of five agency networks – BBDO Worldwide, DDB Worldwide, Omnicom Media Group (OMG), Diversified Agency Services (DAS), and TBWA Worldwide.
As an international marketing and communications services company, Omnicom boasts more than 74 thousand employees in 85 countries and generates nearly half of its revenue from outside Canada and the United States.
