List of Agencies in the Omnicom Network
Updated Q2 2025: Omnicom Group Inc. has never been one to sit still. Known as a global media, marketing, and corporate communications powerhouse, the holding company continues to evolve at a rapid pace, operationally, creatively, and strategically.
One of the biggest plays to date? The $13.3 billion all-stock acquisition of Interpublic Group (IPG), announced in late 2024, set to make Omnicom the largest advertising holding company in the world with combined revenues of $25.6 billion. The merger is projected to generate $750 million in annual savings through office consolidation, procurement efficiencies, and workforce optimization. Staff costs are expected to shrink by 10%, mostly in middle management and regional operations, while client-facing roles are being preserved.
But scale isn’t the only story of Omnicom.
Omnicom’s digital transformation efforts are in full swing, powered by investments in AI and advanced analytics to supercharge creative, media, and commerce solutions.
In Q1 2025, Omnicom Media Group posted 199 new business wins, outpacing its nearest competitor by more than 275%. The company reported a 3.4% increase in organic revenue to $3.7 billion, with net income reaching $287.7 million. Trailing twelve-month revenue topped $15.75 billion—a 5.84% increase year-over-year.
While the Omnicom name is as familiar a word for agencies as RFP, the history of the holding company is less discussed.
It all started in 1986, when Allen Rosenshine, Keith Reinhard, and John Bernbach merged BBDO Worldwide, Doyle Dane Bernbach, and Needham Harper Worldwide to create Omnicom Group. Since then, the company has built a legacy across four core disciplines:
- Advertising
- Customer Relationship Management (CRM)
- Public Relations
- Specialty Services (media buying, digital marketing, sports and event marketing, field marketing, brand consultancy)
In the late 1990s, Omnicom was a dominant force. At the 1996 Cannes International Advertising Festival, DDB Needham earned more awards than any other agency in the world. The next year, Fortune named Omnicom the most respected ad group, while The Wall Street Journal ranked it No. 1 in total return to shareholders—an accolade it held until 2006.
Culturally, the company has continued to evolve. Omniwomen, launched in 2014 to elevate female leadership, has grown into a global initiative with more than 10 branches spanning the US, UK, Canada, France, Germany, China, and the UAE.
