Omnicom Group is a globally connected network of premier marketing communications companies, known for its ability to deliver top-tier talent, creativity, technology, and innovation to some of the world's most renowned and successful brands.

Omnicom's branded networks and specialty firms provide services in four disciplines: advertising, customer relationship management (CRM), public relations and specialty services. The services included in these disciplines are media planning and buying, digital and interactive marketing, sports and events marketing, field marketing and brand consultancy.

With over 5,000 clients across more than 70 countries and a workforce of over 70,000 individuals, Omnicom's commitment to leveraging collective and individual strengths ensures they drive results that positively impact their clients' bottom lines.

At the core of Omnicom's portfolio are three global advertising agency networks - BBDO, DDB, and TBWA - along with the Omnicom Media Group, a global media network featuring OMD, PHD, and Hearts & Science. They also oversee the DAS Group of Companies, which encompasses the Health Group, Precision Marketing Group, Commerce Group, and Advertising Collective. In 2021, they introduced the Communications Consultancy Network (CCN), including agencies like FleishmanHillard, Ketchum, Marina Maher Communications, Porter Novelli, and more. Omnicom Group Inc., headquartered in New York City, continues to be a leading figure in global media, marketing, and corporate communications, serving clients in over 100 countries and across a wide range of advertising, CRM, public relations, and specialty services.

In 1986, Allen Rosenshine, Keith Reinhard, and John Bernbach (son of William Bernbach) founded Omnicom through a merger of three companies: BBDO Worldwide, Doyle Dane Bernbach, and Needham Harper Worldwide. In 1989, Rosenshine stepped down as chairman of Omnicom to return to his position at BBDO Worldwide, and Bruce Crawford, who had been CEO of BBDO before leaving to work at the Metropolitan Opera, took over as chairman of Omnicom. In 1997, John Wren, who was the second-in-command at Omnicom, became the company's CEO, while Crawford remained as chairman.

In July 2013, it was announced that Publicis Groupe and Omnicom Group would merge to create Publicis Omnicom Group. However, by May 2014, the merger was cancelled, and the deal no longer went through.

By 2014, Omnicom had become the second-largest advertising holding company, with revenues surpassing $15 billion. That year, Omnicom launched Omniwomen, an initiative to increase the number and influence of women in leadership roles within the company. Omniwomen has since expanded with branches in countries including the US, UK, Canada, France, Germany, China, and the UAE.

In July 2017, Omnicom welcomed Gracia Martore, former president and CEO of TEGNA Inc., to its board of directors. Her appointment increased the number of independent directors to 13, with 11 being independent. In February 2018, Ronnie S. Hawkins was also appointed as an independent director, bringing the board's total to 14 members, 12 of whom were independent. In May 2018, Omnicom expanded its language strategy agency, maslansky + partners, into Australia.

In November 2021, Daryl Simm was promoted to president and COO of Omnicom. The following month, Florian Adamski was named the new CEO of Omnicom Media Group after previously serving as CEO at OMD Worldwide.

In October 2023, Omnicom acquired the e-commerce company Flywheel Digital for $835 million. Flywheel had previously been a subsidiary of the UK-based company Ascential.

In December 2024, Omnicom Group entered into discussions with Interpublic Group (IPG) about a potential merger. The new company would continue to operate under the Omnicom name, trading on the New York Stock Exchange as "OMC," with John Wren remaining as chairman and CEO, and Phil Angelastro serving as CFO and executive vice president. In June 2025, the FTC approved Omnicom's $13.5 billion acquisition of Interpublic, though both companies had to agree not to block political-based advertisements. The merger was completed on November 26, 2025.
