Jon Cook is leaving WPP after three decades, marking the end of one of the holding company's longest continuous executive tenures at a moment when VML—the $4.2 billion revenue unit formed from the 2023 merger of VMLY&R and Wunderman Thompson—faces ongoing integration pressure and creative attrition questions.
Cook joined what was then Y&R in the mid-1990s and rose through multiple agency reconfigurations under WPP's rolling consolidation strategy. His departure follows a 12-month period during which VML lost its global chief creative officer, saw account defections in North America, and struggled to articulate a distinct positioning against Publicis Groupe's creative commerce units and Omnicom's Omnicom Advertising Group structure. Ad Age first reported the exit, noting no immediate replacement announcement and no clarity on whether Cook's role—most recently overseeing creative for key technology clients—will be backfilled or absorbed.
The move matters because VML represents WPP's largest single creative entity after CEO Mark Read's decision to collapse overlapping networks into fewer, theoretically more competitive units. Cook's exit removes institutional memory at a time when holding companies are navigating 40-60 day client decision cycles, compressed briefs, and creative leaders moving to in-house studios or independent shops at accelerating rates. VML's North American operation, which Cook helped anchor, has faced particular scrutiny since the merger failed to produce the projected $200 million in cost synergies Read telegraphed to investors in early 2023.
For family-office principals tracking media and marketing services exposure, the signal is structural: WPP's multi-brand consolidation strategy—designed to compete with consulting firms and platform in-house teams—is producing executive churn at the senior creative level, the exact layer clients pay premium rates to access. Cook's departure adds to a pattern seen at Ogilvy, GroupM's content units, and now VML, where long-tenured leaders exit without clear succession messaging. This creates opportunity for independent agencies and boutique networks to poach mid-level talent and pitch clients on stability, a reversal of the holding-company value proposition from 2010-2020.
Operators should watch for three follow-on moves in the next 90 days: whether VML announces a new North American chief creative officer or folds the role into a global structure, which clients Cook serviced and whether they move reviews, and whether WPP adjusts VML's revenue guidance in the Q1 2025 earnings call. Any of those would clarify whether this is standard attrition or a signal that Read's integration model is producing unintended fragility at the creative core.
Cook's three-decade run ends as WPP trades at 8.2x forward earnings, below Publicis and Omnicom, with investors pricing in operational risk the holding company insists it has contained.
The takeaway
Jon Cook's WPP exit after 30 years removes senior creative continuity at VML as the $4.2B unit navigates post-merger integration and client retention pressure.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
