Editorial Assessment
McCann Worldgroup is one of the world's leading global advertising agency networks, headquartered in New York City. McCann traces its origins to 1902, when Alfred Erickson founded the H.K. McCann Company in New York. After a series of mergers and rebranding — most notably merging with Erickson Advertising in 1930 to form McCann-Erickson — the agency became a defining force in twentieth-century advertising, coining one of the most famous advertising philosophies: 'Truth Well Told.' McCann Worldgroup operates today as a key agency network within Interpublic Group (IPG). McCann Worldgroup encompasses multiple specialist agencies under its umbrella, including McCann (creative advertising), MRM (digital and CRM), Weber Shandwick (public relations, now also an IPG standalone network), Commonwealth//McCann (dedicated automotive agency), UM (Universal McCann, media), and Momentum Worldwide (experiential marketing). The network operates across more than 120 countries, making it one of the broadest-reaching agency networks globally. McCann is particularly famous for its work with long-standing clients including Mastercard — for whom it created and has maintained the legendary 'Priceless' campaign since 1997, one of the longest-running and most recognisable advertising platforms in history. Other major clients include General Motors, L'Oréal, Nestlé, Microsoft, Hershey's, and the US Army. McCann consistently ranks among the most awarded agency networks globally, winning multiple Agency of the Year honours at Cannes Lions and other major festivals. The network's creative philosophy centres on finding human truths that connect brands to people.
