About

Formerly one of the four largest global advertising holding companies; now a wholly-owned subsidiary of Omnicom Group following the November 2025 merger close, forming the world's largest advertising group.

Interpublic Group (IPG) was an American advertising and marketing services company headquartered in New York City, which was acquired by and folded into Omnicom Group in 2025. Its portfolio included five major networks — FCB, IPG Mediabrands, McCann Worldgroup, MullenLowe Group, and Marketing Specialists — along with independent specialty agencies in public relations, sports marketing, talent representation, and healthcare. IPG Mediabrands, with over 13,000 media and marketing specialists operating across more than 130 countries, served clients in automotive, entertainment, financial services, and retail, with capabilities spanning media planning and buying, digital media, and branded content. Shortly before the Omnicom merger, IPG moved to strengthen its data and commerce capabilities through the acquisition of Intelligence Node, an e-commerce intelligence platform, with its CEO citing actionable data as paramount to maximizing brand performance as commerce and retail media converged. On the financial and legal front, IPG paid $115 million in 2003 to settle class action lawsuits brought by shareholders following accounting irregularities that led to restatements of financial results.
