In plain English
Omnicom is the world's largest advertising and marketing group — a holding company that owns hundreds of creative, media-buying, PR, healthcare and data agencies (BBDO, DDB, TBWA, OMD, PHD, Flywheel). Brands hand it their marketing budgets; Omnicom turns them into campaigns and decides where the ad money flows across Google, Meta, Amazon and TV. In November 2025 it absorbed rival Interpublic in a ~$13.25B all-stock deal, vaulting past WPP and Publicis to the top of the industry.
