McCann

One of the world's largest and oldest advertising agency networks within the Interpublic Group holding company

McCann Worldgroup is one of the world's largest and most established advertising agency networks, operating as a subsidiary of Interpublic Group of Companies (IPG). Founded in 1902, McCann has evolved from a traditional advertising agency into a comprehensive marketing communications network that provides creative advertising, strategic planning, media services, digital marketing, and brand consulting. The network operates through several specialized units including McCann (the flagship creative agency), MRM (relationship marketing and digital), Momentum Worldwide (experiential marketing), McCann Health (healthcare communications), and CRAFT (global production). McCann serves major global brands across virtually every industry sector, with a client roster that has historically included Coca-Cola, Microsoft, Mastercard, and General Motors among others. The agency network maintains a presence in over 120 countries with more than 20,000 employees worldwide. McCann positions itself as a leader in integrated marketing communications, combining data-driven insights with creative excellence to deliver campaigns across traditional and digital channels. As part of IPG, McCann benefits from access to broader resources and technology platforms while maintaining its distinct brand identity and operational structure within the holding company ecosystem. In the AdTech and MarTech landscape, McCann operates primarily as a creative and strategic services agency rather than a pure technology platform provider. However, the network increasingly integrates marketing technology, programmatic advertising capabilities, data analytics, and digital platforms into its service offerings to meet evolving client needs in the digital advertising ecosystem.
