Welcome in, today is Friday, October second, and we begin with AdExchanger's report that Apple's newest operating system has cut The Trade Desk off from Safari. On the adtech side, AdExchanger reports that The Trade Desk is unable to serve ads to Safari on Apple devices running iOS twenty-seven, the latest operating system update. We have not seen that matched elsewhere. The same account dates that release to September fourteenth, and says Apple has been investigating since last week with no resolution yet. For buyers routing Safari inventory through the largest independent demand-side platform, that is a delivery gap with no confirmed cause, bug or deliberate change. Industry reaction leans toward reading the block as deliberate: some practitioners note it swept in a set of shared cross-site identity solutions at once, and that using one domain for both identity syncing and ad delivery turned an identity restriction into a total serving outage. Also today, Advertising Week New York opens Monday at the Penn District and runs through October eighth, and Marketing Dive reports it is reweighting the agenda toward creators on an increasingly crowded fall calendar. Per that reporting, about one thousand creators attended as delegates last year, a figure the event's global president expects to more than double this year, and the show is introducing a challenge to generate one hundred million dollars in creator-brand deals across its four days, built with entrepreneur Dhar Mann as chief creator officer. The same account puts last year's attendance above twenty thousand, and notes this is the first edition since owner Emerald was acquired by Apollo Global Management in July and merged with Questex into a new company, Forge. It lands the same week as the VidCon x Lions showcase in Denver and the new Jupiter Festival. The IAB forecasts United States creator-economy ad spend rising nearly nineteen percent to forty-four billion dollars this year. Some in the trade read stage-set deal targets as aspiration running ahead of committed spend. Separately, on the platforms side, Paramount Skydance and Warner Bros. Discovery say they have set an anticipated closing date for their merger, in a joint release dated September thirtieth. Put a date on that close and agency buyers are negotiating with one seller across CBS, Paramount Plus, HBO Max, CNN and the Warner cable networks. That release states timing only, and the closing remains conditional, so inventory, pricing and upfront implications are not yet specified. Industry reaction leans less toward approval than execution: some in the trade point to unresolved decision rights after closing, and to culture integration across two large workforces. Also today, AdExchanger argues that agencies are rethinking whether they should own the agentic AI tools they build for brand clients, or the data behind them. For years, that piece says, holdco competition ran on assembling the best data and tech stacks. Now the differentiation is custom agentic tooling, with agencies less interested in owning the data that powers it, and rethinking owning the tools themselves. It reframes how holdcos have differentiated for years, and ownership terms are still unsettled. Reaction in the trade leans toward the view that agentic tools live or die on the data substrate beneath them, clean inputs, a single system of record, and a named human who owns the failure, which some read as putting the durable value on the client's side. Now, a few more headlines moving the trade today. The Media Leader has Stagwell chief executive Mark Penn making the case for his group as a fourth alternative to the Big Three, and bullish on AI in production and media targeting. Campaign has Havas chief executive Yannick Bolloré on principal media buying and creative-unit independence, arguing the tier below the Big Three trades scale for speed. Gartner says many marketers will be able to eliminate bottom-rung roles by twenty thirty, and recommends handing new hires greater responsibility instead, according to Marketing Dive. Cava has hired John Ludeke, most recently chief brand officer at Dr. Squatch, as chief marketing officer, per Marketing Dive. Campaign reports WPP Media has confirmed the departure of Sindhuja Rai, its regional chief client officer in Asia Pacific, with no successor named. And finally, on the platforms side, Digiday reports Amazon estimates about a fifth of a brand's sales value arrives after the attribution window closes, drawn from more than two million campaigns; agency buyers in that account want independent verification before moving budget.
