Omnicom Group and Interpublic Group (IPG) have officially confirmed their global merger in a deal valued at US$13.5 billion, marking the most significant structural shift in the advertising industry in decades. The operation is set to create the world’s largest holding company, with a combined estimated annual revenue of US$25.6 billion.
The groundbreaking agreement includes a historic decision: the dissolution of the DDB network, one of the most influential brands in the history of modern creative advertising.
The U.S. Federal Trade Commission (FTC) approved the merger under an integration scheme that will consolidate the new group’s creative operations around three core global agency networks: BBDO Worldwide, McCann (simplifying its name from McCann Worldgroup), and TBWA\Worldwide.
The definitive closing of the merger process is expected in the fourth quarter of 2025. This integration will directly impact regional operations, leadership structures, and the brand identity of several historic agencies across the globe.
