## Business segments

Omnicom reports one reportable segment, comprising its advertising, marketing and corporate communications services businesses; this consolidated segment represents 100% of reported segment revenue. The company also identifies four operating segments (agency networks), which it aggregates into the single reportable segment rather than presenting as separate reportable segments. [19](https://app.finbar.com/go?id=P11425374)

Omnicom describes its services through seven disciplines: Media & Advertising (media planning, buying and optimization, analytics, creative services and content production); Precision Marketing (digital transformation, decision sciences, digital experience design, CRM and e-commerce); Public Relations (corporate communications, crisis management, public affairs and media relations); Healthcare (communications, advertising and media services for healthcare and pharmaceutical companies); Branding & Retail Commerce (brand and product consulting, strategy, research and retail marketing); Experiential (live and digital events and experience design); and Execution & Support (field marketing, sales support, merchandising, point-of-sale and product placement). The company does not disclose revenue percentages for these disciplines, so their individual contributions cannot be quantified from reported data. [20](https://app.finbar.com/go?id=P122412676)

## Company history

Omnicom was formed in 1986 through the merger of BBDO, Doyle Dane Bernbach and Needham Harper Worldwide, bringing three established advertising agency networks together under one holding company. [21](https://www.omc.com/wp-content/uploads/2020/12/omnicom-one-page-final.pdf) In 1993, it agreed to bring the TBWA network into the group; in 1998, it pursued the GGT agency group and combined GGT/BDDP Worldwide with TBWA International. [22](https://www.lesechos.fr/1993/03/lamericain-omnicom-reprend-tbwa-sous-son-aile-901090) [23](https://www.independent.co.uk/news/business/ggt-accepts-pounds-143m-bid-from-omnicom-1141574.html) [24](https://www.lesechos.fr/1998/05/le-geant-americain-omnicom-organise-la-fusion-de-ggt-bddp-avec-tbwa-792326)

John Wren became president in 1996, CEO in 1997 and chairman in 2018. [25](https://www.omc.com/about/people/john-wren/) Omnicom and Publicis announced a proposed merger in 2013, but mutually terminated the agreement in May 2014 after they could not complete it within a reasonable timeframe. [26](https://www.publicisgroupe.com/sites/default/files/press-release/20140509_09-05-14_PRESS_RELEASE_ENG_FINAL.pdf) In November 2025, Omnicom completed its merger with Interpublic Group (IPG), which became a wholly owned subsidiary.
