Sixteen months after finding that Google had illegally monopolized two markets, the judge who made that finding declined to take anything away from it.

On September 2, 2026, Judge Leonie Brinkema of the United States District Court for the Eastern District of Virginia ruled that Google will not be required to sell its AdX exchange or its DFP publisher ad server. Instead she adopted most of the behavioral remedies that the Department of Justice and Google had each proposed, a set of obligations that rewrites how the open-web display auction works without changing who owns it. Her written opinion is sealed for fourteen days while both sides review it for confidential material, which means the industry spent the day arguing about a decision it has not read.

The remedies are not trivial. They dismantle the specific mechanisms that the April 2025 liability ruling identified as the instruments of the monopoly. They also leave in place the ownership structure that made those mechanisms possible in the first place, and that is the tension the next several years will be spent testing.

What the court refused to do

The liability finding came on April 17, 2025. PPC Land reported at the time that the court had found Google monopolized the publisher ad server market and the ad exchange market for open-web display advertising, under Sections 1 and 2 of the Sherman Act, with Google holding 91 percent of the publisher ad server market. Brinkema wrote then that Google had willfully engaged in a series of anticompetitive acts to acquire and maintain monopoly power. One government count failed: the court found insufficient evidence of monopolization in the proposed advertiser ad network market.

The remedies phase ran from September 22 to October 6, 2025. Final briefs landed on November 3, 2025, and PPC Land set out what each side had asked for. The Department of Justice wanted AdX divested within twelve months, DFP's final auction logic open-sourced within twelve months under a neutral administrator such as Prebid.org, and a contingent divestiture of the remaining ad server components triggered at the three-year mark if competition had not returned. It asked for ten years of behavioral restrictions on top, a six-year independent trustee with full source code access, and an escrow fund to cover publisher switching costs.

Google proposed behavior alone, monitored for six years: real-time AdX bids made available to rival publisher ad servers, unified pricing rules removed, a commitment never to rebuild first look or last look, equal latency and data signals across pathways, and no differential revenue sharing based on which ad server a publisher chooses.

Closing arguments on November 21, 2025 telegraphed the outcome. PPC Land's account of that hearing recorded Brinkema's skepticism about divestiture in almost the terms she has now adopted: the industry landscape changes rapidly, and predictions about market conditions five years out remain uncertain. Matthew Huppert argued for the government that behavioral remedies would entangle the court in endless litigation and that only divestiture could remove illegally acquired monopolies. Karen Dunn argued for Google that behavioral relief could be implemented within twelve to eighteen months and that a publicly traded company's accountability was sufficient guarantee. Ari Paparo, watching, said the judge's skepticism was enough to sway him that the spinout was not going to happen. He was right, though the ruling arrived roughly seven months later than the January or February 2026 timeline Brinkema had suggested from the bench.

The reasoning reported on September 2 rests on four practical objections rather than any softening on liability. There is no obvious buyer, since Microsoft would trigger an antitrust review of its own. The market moves faster than a three-to-five-year divestiture process can anticipate. Appeals would postpone any relief for years. And small publishers currently using DFP without charge could be harmed by disrupting the service. Behavioral remedies, by contrast, can begin to be enforced within a year.

Google's response was brief and precise about what it had won. Lee-Anne Mulholland, a vice president at the company, said it was very pleased that the court rejected the proposal to break apart tools that help small businesses reach new customers and grow. Search Engine Roundtable, recording the ruling the same morning, noted the framing circulating in wire coverage: the ad exchange is a small part of Google's business, and the decision is a second symbolic defeat for the Department of Justice after the search case also ended in behavioral rather than structural relief.

The mechanisms the order takes apart

The substance of what Brinkema ordered is more specific than the headline suggests, and it maps closely onto the conduct catalogued at trial.

Real-time bid data from AdX must be made available to rival ad servers. Unified pricing rules are to be deprecated. Publishers in Google Ad Manager will be able to set different price floors for individual bidders. First look and last look are prohibited on open-web display inventory. Divestiture is off the table, and so, for now, is the idea of handing AdX integration to Prebid.org, though Google signalled it would support that step.

Each item on that list has a history. Unified pricing rules arrived in 2019 as part of Google's shift to a first-price unified auction, and the company presented them at the time as a simplification. PPC Land covered the announcement, in which Jason Bigler, then a director of product management, said Google would be able to provide publishers with reporting on all bids submitted for their ads, with a limit of 100 unified pricing rules per publisher. What publishers lost in the same change was the ability to price different demand sources differently, which is precisely the capability the court has now ordered restored. Seven years of auction design is being wound back to a state that existed before it.

First look and last look go back further. Index Exchange, which sued Google on November 10, 2025 in the same districtunder case number 1:25-cv-02003, described first look as dating to 2010, giving AdX the first opportunity to acquire any impression before other exchanges could bid, and characterised last look as the ability to open the envelope for the winning bid, know what that bid was, and bid after everybody else. Its single-count Sherman Act Section 2 complaint puts the annual value of the affected ad exchange market above 104 billion dollars and also names Project Poirot, the 2017 programme that cut bids on rival exchanges by as much as 90 percent through DV360 while submitting full-price bids through AdX.

Teads followed on August 3, 2026 in the Southern District of New York, case number 1:26-cv-06591, with seven counts. Its central number is arresting: between 2017 and 2023, rival exchanges would have won 6.88 trillion additional impressions had Google Ads bid through both Google and non-Google exchanges in the way its competitors do. That is more than a quarter of rival exchange volume in an untethered market. The complaint states that roughly 90 percent of Google Ads demand flows exclusively through AdX, and that Google Ads accounts for around 30 percent of programmatic impressions.

Those private cases are unaffected by Tuesday's ruling except in one respect: the liability finding they build on survives intact, and the remedies order now supplies a public benchmark for what the court considers adequate relief. Damages claims proceed on their own timetable.

Brussels is on a different track and may yet reach a different place. The European Commission fined Google 2.95 billion euros on September 5, 2025 in Case AT.40670, finding an Article 102 abuse spanning 2014 to 2025, with Google at 91 percent of publisher ad servers and 60 to 70 percent of ad exchanges. The public version of that decision, released as structural remedies remained on the table, documents first look, last look, dynamic revenue share, unified pricing rules and Project Poirot. Google submitted behavioral commitments on November 13, 2025 that closely mirror what a Virginia court has now ordered, and filed an annulment action on January 12, 2026. Teresa Ribera has signalled that structural remedies appear necessary. Competition lawyer Damien Geradin called the proposed behavioral package entirely useless.

So the same catalogue of conduct has produced a behavioral remedy in Virginia and an unresolved structural question in Brussels, on the same evidence.

The industry reaction split along predictable lines. Shamsul Chowhury, senior vice president for paid media at Zeno Group, said Google can take a deep exhale now that their business will remain intact. Jay Friedman, who testified for the government and co-founded the ad tech advisory firm CartographAI, framed the gap the remedies leave open as a question: what is a web publisher to do if it wants to use a different ad server but still get Google's buy-side demand. Real-time bid access is meant to answer exactly that, and whether it does will be the practical test of the order over the coming year.

Mapping a market that will not be redrawn

Friedman's own company published something on September 2 that reads differently after the ruling.

CartographAI, which he founded with Danilo Tauro, a former McKinsey analyst who ran vendor assessment at Procter and Gamble, launched an accelerator programme aimed at ad tech vendors rather than at the brands and agencies it originally served. The core product sorts ad tech into vertical categories, demand-side platforms, identity solutions and the rest, and ranks vendors against five category-specific criteria as emerging, capable or advanced. Roughly 1,000 vendor profiles are visible free after registration, with about 20 added each month. Custom consulting engagements run between 500,000 and 600,000 dollars.

The new accelerator costs between 1,000 and 3,000 dollars a month depending on company size and launched with sixteen participants, among them The Trade Desk, Viant, MNTN and Adelaide. Members get monthly analyst calls, buyer insight, promotion across social channels and podcasts, and co-marketing. Gareth Glaser, chief executive of Gamera, said the programme helps identify the right contacts at brands, agencies and trading desks, with guidance from people who understand how to create the right conversations. An AI analyst tool that recommends vendors against specific challenges and key performance indicators is planned for later in 2026.

There is an obvious structural point to make about a ratings firm selling marketing services to the companies it rates, and CartographAI is not the first analyst business to sit in that position. The more interesting observation is about timing. A market that has just been told it will keep its dominant integrated player, with rule changes rather than ownership changes, is a market where vendor selection carries more weight than it would in a world where AdX had been forced into independent hands. If the structure is fixed, navigation becomes the product.

AdSense stops counting ads that never appeared

A second measurement change landed in the same 48 hours, with a longer fuse and a narrower audience.

Google notified publishers on September 1 that from February 17, 2027, AdSense and Ad Manager will count a display impression only once the ad has successfully loaded and started to render on the user's device. The current method counts at the moment the ad begins downloading. Search Engine Roundtable covered the notice on September 2, with Google saying the update aims to provide more consistent measurement and align with industry standards.

The technical detail matters more than the framing. PPC Land's account establishes that the change applies to banner display inventory on web, mobile web and connected television, while native, interstitial, video and application formats already count on begin-to-render or an equivalent. The methodology itself is not new: it comes from IAB Technology Laboratory and Media Rating Council guidance published in October 2017. Google's own buying platforms, Display and Video 360 and Campaign Manager 360, moved to begin-to-render during 2025. The seller-side products follow seventeen months later, which means that for more than a year Google's buyers and Google's sellers have been counting the same event by different rules.

Impression counts will fall. Every download that never completed rendering, because a user navigated away, because a script failed, because a connection dropped, disappears from the total. Google has published no estimate of how far. That silence is a departure. When AdSense made a comparable counting change in 2018, the notification included an explicit statement that earnings were not expected to be impacted. No such sentence appears this time.

The comparison window is the practical constraint. Historical data suitable for estimating the impact begins on August 12, 2026, giving Ad Manager publishers roughly six months of baseline before implementation, and giving AdSense publishers, who lack the equivalent reporting tools, considerably less to work with. Year-over-year dashboards will carry a permanent discontinuity at February 17, 2027, and any publisher whose commercial arrangements are denominated in impressions rather than revenue will be renegotiating against a different denominator. The practice of buffering delivery to compensate for counting mismatches between buyer and seller systems becomes unnecessary, which removes a source of operational slack that some publishers have used deliberately.

Two days earlier, a different Google measurement surface simply stopped working. Google Analytics failed to record September 1 traffic across GA4 properties, showing zero for the day in main charts while sites continued to receive visitors. Dana DiTomaso had flagged processing problems with August 31 data the day before. Rakesh Misra and Erric Ravi reported the September 1 gap, complaints accumulated on the Google Analytics Forums and WebmasterWorld, and Search Engine Roundtable published the incident report at 6:13 a.m. Eastern on September 2. No official statement accompanied it.

Ace Hardware sells the forecast

Away from the courts, a retail media network marked its first year by adding capabilities that describe where the category has got to.

RedVest Media, the network Ace Hardware launched in late 2025, used an upfront event to announce weather-triggered programmatic advertising that adjusts creative messaging automatically as conditions such as rainfall or snowfall change. The same announcement covered control-group measurement for incrementality, a social amplification partnership with Influential connecting brands to vetted creators, a DoorDash integration placing ads on Ace's storefront inside the delivery app, and an audience library rolling out through 2026.

The underlying assets are the reason any of it is saleable. Ace counts more than 80 million loyalty members, over 5,300 stores in the United States and roughly 9,000 worldwide. Molly Hjelm, corporate vice president and head of RedVest Media, described the approach as expanding with intention, and made a competitive argument that is unusual in retail media: Ace has no marketplace competing with its vendors and no strong private label portfolio, so its interests and its suppliers' interests are not in tension in the way they are at retailers that sell against the brands buying their inventory. Analyst Ollie Shayer noted that RedVest's integration with Pacvue puts it into the same unified buying workflows as Amazon and Walmart.

Weather triggering is a well-established programmatic technique rather than a new one, and a hardware co-operative is close to the ideal case for it, since demand for snow shovels, generators, dehumidifiers and roof sealant is driven by conditions that a forecast can anticipate several days ahead. The interesting part of the announcement is the pairing with control-group measurement. Weather-responsive creative is exactly the kind of tactic that inflates conventional attribution, because the same conditions that trigger the advertisement also drive the purchase. Without a holdout, the campaign takes credit for the storm.

The IAB's Guidelines for Incremental Measurement in Commerce Media, published on November 3, 2025, define incrementality as the causal impact of marketing identified by comparing outcomes against what would have happened without the campaign, and rank four families of method by causal strength. Experiment-based approaches, meaning randomised control tests, holdouts and matched markets, sit at the top. Platform-reported metrics and new-to-brand percentages sit at the bottom as hybrid proxies with weak causal strength. RedVest's control groups place it in the strong tier, at least in description. The framework anticipates commerce media spending approaching 100 billion dollars by 2028.

One piece of context sits awkwardly alongside a pitch built on loyalty data. Ace Hardware is a defendant in a proposed class action filed on March 12, 2026 in the Northern District of California, case number 26-cv-2151, before Judge Edward J. Davila. The complaint alleges that the company's website kept transmitting user data through Google Analytics and Bazaarvoice's BV Pixel after visitors rejected non-essential cookies, and that trackers fired before users could interact with the consent banner at all. It cites the federal Wiretap Act, the California Invasion of Privacy Act, the Consumer Legal Remedies Act and the Unfair Competition Law, and puts the amount in controversy above 5 million dollars. The case concerns web tracking rather than loyalty records, but it lands in the same year that the retailer began selling audiences.

The NFL renews with TikTok, one week before kickoff

Sports and short-form video renewed their arrangement seven days before the season starts.

The National Football League and TikTok signed a multi-year extension, announced ahead of the September 9 season opener, that adds three elements to a relationship that already existed. The league will build dedicated hubs inside TikTok GamePlan. Its content joins TikTok Pro Events, with a fan hub launching in the coming weeks offering content discovery, trending video engagement and fan benefits. And the @nfl account and individual club accounts remain available through Pulse Premiere, TikTok's programme for placing advertising adjacent to premium content.

Financial terms were not disclosed, no signing executives were named and no follower or view figures accompanied the announcement, which limits how much can be said about its scale. What can be said is where Pulse Premiere sits in TikTok's advertising architecture. PPC Land documented the wider suite when TikTok rebuilt Pulse around brand-safe trend adjacency with creator and AI tooling, a set of products designed to sell proximity to content the platform can vouch for rather than the open feed. A league with 32 club accounts and a five-month season is close to the strongest possible inventory for that model: reliably scheduled, universally recognised, and safe by the standards any advertiser applies.

The renewal also arrives while TikTok's United States corporate position remains unresolved, with a hearing on the vacatur of the earlier COPPA settlement listed for September 21. Advertisers committing to a season that runs into February are pricing that uncertainty one way or another.
