Marketing Agency

Agency consolidation was the defining story on the services side of the industry this week. Omnicom's decision to merge Mediahub and Hearts & Science is a significant structural move — both agencies have distinct client rosters and cultural identities, and the combination reflects a broader holding company imperative to reduce overhead and present a unified, AI-capable media offering to clients. Digiday's briefing suggests the merger is partly a response to the economics of modern media buying, where AI tooling costs are increasingly embedded in agency deals and eroding margins. Separately, M&C Saatchi's Australian and New Zealand operation completed a management buyout, becoming M+C Saatchi ANZ — a move that gives local leadership greater autonomy and reflects a continuing trend of regional agency carve-outs from global networks seeking leaner structures.
