Interpublic Group of Companies (The)

The Interpublic Group of Companies (IPG) stands as one of the world's premier advertising and marketing services organizations, serving clients across the globe through an extensive portfolio of leading agencies and specialized communications firms. Founded in 1930 as McCann-Erickson following the merger of H.K. McCann Co. and Erickson Co., the company pioneered the holding company model in the advertising industry when it reorganized as Interpublic Group in 1961, creating the first marketing services management holding company structure that would later be adopted industry-wide.

With approximately 51,000 employees operating across more than 100 countries, IPG delivers comprehensive marketing solutions through three primary business segments: Media, Data and Engagement Solutions; Integrated Advertising and Creativity Led Solutions; and Specialized Communications and Experiential Solutions. The company's global agency brands include McCann Worldgroup, FCB, MullenLowe Group, IPG Mediabrands, IPG Health, Weber Shandwick, Golin, Huge, R/GA, and many other specialized firms. These agencies provide services ranging from traditional advertising and creative development to cutting-edge digital marketing, media planning and buying, public relations, data analytics, healthcare communications, and experiential marketing. IPG's data and technology capabilities, anchored by its $2.3 billion acquisition of Acxiom Marketing Solutions in 2018, enable the company to deliver data-driven marketing solutions and advanced targeting capabilities for clients.

In 2024, IPG reported total revenue of $10.7 billion with a market capitalization of approximately $8.94 billion. The company's client roster includes many of the world's most recognizable brands across diverse industries including consumer goods, technology, healthcare, automotive, financial services, and retail. Under the leadership of CEO Philippe Krakowsky, who assumed the role in January 2021, IPG has focused on business transformation initiatives targeting operational efficiency while navigating evolving client needs in an increasingly digital marketplace. The company has been recognized with numerous industry accolades, including being named Holding Company of the Year at The Drum Awards Festival 2024 and earning 18 awards at the ANA Multicultural Excellence Awards, more than any other holding company.

In December 2024, Omnicom Group announced plans to acquire IPG in a stock-for-stock transaction valued at $13.5 billion, creating what would become the world's largest advertising holding company with combined revenues exceeding $25 billion. The acquisition was completed on November 26, 2025, following regulatory approvals from authorities in the United States, United Kingdom, European Union, and Australia. Under the new structure, IPG operates as a subsidiary of Omnicom Group, with Philippe Krakowsky serving as Co-President and COO of the combined entity alongside Daryl Simm. This historic merger marks the end of IPG as an independent company after more than six decades as a publicly traded organization, bringing together two of the industry's "Big Four" holding companies to create an advertising and marketing powerhouse positioned to serve clients with unprecedented global reach and integrated capabilities.
