Warren here, with Charlie chiming in as usual. Omnicom is now the largest advertising and marketing services company in the world, having completed its all-stock merger with Interpublic Group on November 26, 2025. The combined company plans media campaigns and buys advertising space for clients (Integrated Media, $3.26 billion of the $6.56 billion in second-quarter revenue), creates the ads themselves (Advertising, $1.08 billion), runs public relations ($709 million), does specialized healthcare marketing ($586 million), and handles events, sports marketing, branding, and merchandising (Experiential & Other, $929 million). It operates everywhere — 61% of revenue from North America, 26% from Europe/Middle East/Africa, 9% from Asia-Pacific. The business model is simple to state: large corporations pay Omnicom fees to make their products famous and their marketing dollars efficient.
