Welcome in, today is Monday, October nineteenth, and we begin with WPP's pick to run its creative business, per Brand Spur. Brand Spur reports that WPP has appointed Tyler Turnbull, the outgoing global chief executive of McCann, to head WPP Creative from early twenty twenty-seven. He succeeds Jon Cook, with a remit to pull the group's creative agencies closer to its media, data, production, commerce and technology operations, and to make wider use of WPP Open, the group's AI marketing platform. That fixes the shape of creative leadership at a holding company clients will be pitching into long before the handover lands. Per that account, Turnbull spent twelve years at FCB before McCann, which moved under Omnicom after its acquisition of Interpublic. Chief executive Cindy Rose said he has the international experience to guide the creative business through its next phase. The same reporting says Cook will leave after three decades with the group, staying in post until March. Eric Campbell is expected to take over as VML's global chief executive that month. Also today, Digiday reports on Dentsu's plan to make entertainment a part of every brand's budget. That account frames entertainment as the next agency account up for grabs, with advertisers funding it as its own line rather than as an occasional extension of a campaign. A budget line of its own is also a line agencies can be made to pitch against each other for. Industry reaction leans toward reading the move less as media buying and more as the agency taking a financing stake, and some in the trade argue that getting in while a story is still being shaped gives brands options that buying exposure after production does not. A recurring caveat is that the product still needs a credible reason to be in the story. Separately, Sam Bradley writes in Digiday that guitar brand Fender and amp maker Marshall have both launched content series aimed, in part, at improving how they show up in AI search answers, and that the two are examples of a wider pattern. That account does not establish effect. There is no settled evidence yet that publishing a series moves AI-generated answers, which leaves budget going into a channel the trade cannot yet measure. Reaction leans toward framing owned editorial as a way to feed models something citable, on the logic that brands cannot instruct chatbots how to describe them, though much of that enthusiasm comes from the content-marketing supply side. A contrarian strand holds the lever is format variety, not volume. Staying with that measurement problem, Aaron Baar reports in Marketing Dive that a growing number of marketers are taking influencer measurement into their own hands, spending more to amplify creator content as a workaround. That moves the gap out of the reporting deck and onto the media budget. Among practitioners, a recurring view is that the method decides the verdict, with discount codes and last-click reads treated as understating creator impact, and some pointing to incrementality or holdout testing as producing markedly better results for the same campaign. Some read the shift as creators now being judged on whether their content holds up as paid media rather than on reach or follower counts. Now, a few more headlines moving the trade today. On the platforms side, Adweek reports Fox has added Omnicom, Stagwell and Simulmedia as agentic buying partners and is now executing linear transactions. Also across the category, Campaign India argues X's global lead-generation rollout is a test of whether performance tooling can offset brand-safety objections, while Threads still draws no budget line of its own. Marketing Dive reports Arby's has hired former Papa Johns marketing chief Jenna Bromberg, effective November second, as parent Inspire Brands weighs an initial public offering. And finally, following our earlier report on the launch of Stagwell Media, Market Screener reports Stagwell has named Nagmeh Taheri chief growth officer for media and commerce in Europe, effective November eighteenth.
