Omnicom Group
Omnicom Group Inc. (NYSE: OMC) is the world's largest marketing and sales communications holding company, formed in its current shape when Omnicom completed its acquisition of Interpublic Group on 26 November 2025, combining pro forma revenue in excess of $25 billion. The company operates across advertising, media, precision marketing, commerce, public relations, healthcare, branding, experiential and production, serving clients in more than 100 countries through agency networks including BBDO, DDB, TBWA, OMD, PHD, Hearts & Science, McCann, FCB, Mediabrands, Flywheel and Acxiom. Its Omni platform — built and operated by Annalect, Omnicom's data, technology and AI division — is marketed as an AI-driven marketing intelligence operating system spanning orchestration, production, predictive intelligence and outcome-driven activation, and is grounded in Acxiom Real ID identity data. As of the 2026-08-12 probe, Omnicom publishes no public developer program: no developer portal, API reference, OpenAPI/AsyncAPI/GraphQL document, SDK, MCP server or A2A agent card is served from any Omnicom host. The corporate site moved from omnicomgroup.com to omc.com, which 301-redirects the legacy domain.
Omnicom Group is profiled on the APIs.io network. Tagged areas include Fortune 500, Advertising, Marketing, Holding Company, and Media.
