Jensen Huang quits Nvidia as Google gives every searcher Gemini 4 Hydrogen

PPC Land is now also on WhatsApp, with a new PPC Land channel carrying its stories.

On Thursday, November 12, 2026, the company whose chips power the AI boom lost the man who built it, and the company that sells the most advertising against AI answers handed its newest model to everyone who searches. Nvidia said Jensen Huang had resigned as president, chief executive and board member, effective immediately, ending 33 years in charge. A few hours later Google rolled out Gemini 4 Hydrogen in Search globally and for all users, making it the default model in AI Mode. Around those two events ran a long day of smaller ones: Google Ads showing advertisers for the first time how much invalid traffic it did not bill them for, European regulators tightening the rules on cross-site tracking, broadcasters cutting forecasts, and brands hiring creators to make television rather than posts.

The Landline newsletter can also be heard. Marketing Is Calling reads each edition aloud every day, on Spotify, Apple Podcasts and YouTube. Marketing Rodeo picks the most controversial advertising story of each day, weekends included, and has some fun with it, on Spotify, Apple Podcasts and YouTube.

Nvidia loses its founder

Huang turned a graphics card business into the engine of the AI economy, and for more than three decades he was the face of Nvidia. His resignation followed reports that he had an extramarital affair with a woman alleged to be a Chinese spy and another with an Nvidia direct report. Chief financial officer Colette Kress becomes interim chief executive while the board searches for a permanent successor. PPC Land reported that Huang exits Nvidia after 33 years with no permanent successor, and that Harvey C. Jones, a former Synopsys chief executive and a director since 1993, becomes the board's first chair. "The Board has full confidence in Colette and the leadership team," Jones said. Nvidia shares had closed at a record $239.24 on October 6 and fell to an overnight low of $156.20, and third-quarter results are due on November 17.

The news broke during CNBC's morning programming. Anchor Carl Quintanilla told TVNewser that the network had been bracing for it all week. "It has the potential to be the biggest corporate scandal in decades," he said. "We'd been bracing for news. This thing had been building up to a crescendo all week." Adweek's Kendra Barnett, opening her weekly AI, Tech and Money newsletter, called it "the spectacular downfall of Nvidia CEO Jensen Huang."

Google's biggest model reaches every search

Google described Hydrogen as the largest single change to its search engine's model. "It's the biggest model improvement to Search yet. And it's available now for all users, globally," wrote Nick Fox. Robby Stein said Hydrogen is now the default in AI Mode and is used for harder questions in AI Overviews. Google's launch post lists four areas of improvement: understanding complex or misspelled questions, fanning queries out across subtopics and surfacing a broader set of links, richer visual answers with tables and custom tools, and more nuanced responses in every AI Mode language. The launch landed in the middle of the November 2026 core update, and Barry Schwartz expects Hydrogen to change AI Overviews and AI Mode rather than core rankings.

Google's models are also judged on Google's own tests. Google DeepMind and Artificial Analysis released a Multimodal Knowledge Agent benchmark on November 10, and PPC Land found that Anthropic's Claude Fable 5.2 edges Gemini 4 Carbon on it at six times the cost. Google's blog says Carbon ranks second "in quality among the models we tested" without naming the leader. The 25-page report puts Fable first at 73.26% weighted satisfaction against Carbon's 71.89%, a gap it calls statistically insignificant, with average costs per task of $35.28 and $5.63.

Gemini is moving into phones too. Google extended Gemini's ability to operate food, ride and reservation apps to the UK, India and Japan, bringing the beta to five countries, without saying which apps are supported or how Gemini chooses between competitors. In the browser, Google published a guide that steers Chrome users to Gemini for product details and reviews, showing Gemini summarising the reviews on a product page. PPC Land cited a UC San Diego study in which readers of AI review summaries said they would buy 84% of the time, against 52% in a comparison group.

The traffic consequences are now measurable at scale. SparkToro, using Similarweb clickstream data, reported on November 10 that visits to the top one million websites have fallen 12.2% since early 2022, from 2.243 trillion a quarter to 1.970 trillion, while the online population grew about 24%. The top 100 sites raised their share from 33.3% to 36.2%. "But we know that total web traffic and visits-per-Internet-connected human are down from their peak in 2021/22," wrote Rand Fishkin. News sites feel it most. Press Gazette's October ranking showed that only 10 of the 50 largest English-language news sites grew year on year, with The New York Times the sole top-ten riser at 684.7 million visits, up 11%. Chartbeat data cited by PPC Land put search at 12% of North American publisher pageviews in the third quarter, down from 21% a year earlier. The journalism trade is shrinking with it: the Online News Association cuts five staff and pauses its conference after 26 years. "The costs of large convenings have climbed sharply while professional development and sponsorship budgets have shrunk," said chief executive Niketa Patel.

Google itself published a help page on identifying Google Search traffic in analytics and server logs, and PPC Land explained why analytics will not match Search Console click counts. Google Search sends only the scheme and host as a referrer, Discover and Images clicks look identical to Search, and only the Android app identifies itself. The documentation concedes that the method "isn't exact." The page says nothing about AI Mode or Gemini referrals.

Rivals pitched the opposite. Microsoft promoted an extension that turns off AI answers in Bing but also makes Bing the default search engine, alongside an "-ai" operator. "Simply add -ai to any Bing search to get results without AI-generated answers," Microsoft wrote. Schwartz noted that neither method is a search setting. Opera said its iPhone browser gained 46% more US users in a year and brought its Data Saver to iOS. "As the web gets heavier, people everywhere want more control over their data use," said Jorgen Arnesen, executive vice president for mobile.

Agents become customers, and nobody can count them

Venture capital declared the shift. Andreessen Horowitz partners Olivia and Justine Moore published "Welcome to the B2A Economy" on November 11, arguing that companies must court AI agents as agent traffic grew eightfold in two months. "The primary users of the Internet are no longer human. They're AI agents," they wrote. Citing HUMAN Security, they said Meta's Muse made 59% of agent requests on HUMAN customer sites in October and OpenAI products 30%. PPC Land noted that the traffic chart measures all bots and that audits by DataDome found only 2.4% of 21,491 sites blocked all ten test bots. Shoppers are less keen. A Salesforce survey of more than 2,500 people found that 76% do not want a personal AI agent buying for them, and 27% of agent users said one had bought something too expensive. Salesforce still projects $75.8 billion in AI-driven Cyber Week spending. "Shoppers are starting with AI this season," said Caila Schwartz of Salesforce.

Measurement has not caught up. After four months of work, the IAB published an AI-Era Attribution Blueprint on November 12, and its vice president of AI, Caroline Giegerich, said it became a call to action because the key evidence sits inside AI platforms. Similarweb data in the briefing showed that consumers who get an AI brand recommendation are 2.5 times more likely to visit that brand's site within a week, but only 8.8% of those visits arrive as AI referrals. "Publishers are feeding the answers but they don't have the receipts," said Jaime Schultheis of Bombora.

Some publishers want receipts in cash. RSL is renaming itself the Internet Licensing Collective and moving to collective licensing, and Yahoo becomes its first licensee, paying a blanket fee to use content in its Scout AI search engine. More than 3,000 publishers belong, and royalty pools are segmented by AI company. "It's kind of like Spotify, but also a song is a song is a song, and content is very different," said co-founder Doug Leeds, who would not disclose the fee. AI companies are also policing manipulation of their own answers. Anthropic's rewritten Usage Policy, in force from November 12, bans Claude-built fake sites aimed at gaming AI answers, in a new section on deceptive campaigns and artificial activity covering fake personas, concealed sponsorship and networks of sites posing as unaffiliated sources.

OpenAI kept building its own ad machine. Its weekly ChatGPT Ads email renamed automated bidding "intelligent bidding" and introduced Target CPA and Target CPC, with Max Bid and Max CPC retiring for existing campaigns on January 1, 2027. Product feed campaigns can now target regions within a country, and product sets accept multiple filters. The email warned that actual costs "may be higher or lower" than the targets.

In Scandinavia, a publisher is fighting the platforms with their own methods. AdExchanger reported that custom ad algorithms are helping Schibsted win budgets back from Meta, using optimisation engines from London's Nodals AI built on Schibsted's first-party data and sold on cost per click. Schibsted pitches for about 10% of a brand's Meta spend. "Advertisers have been trained by Meta to just care about 'I put money in and I see how much money comes out,'" said Nodals founder Aly Nurmohamed.

Google Ads opens its books on invalid traffic

Google answered a long-standing complaint. A new Invalid Traffic overview card in Google Ads shows two figures: Estimated Savings, filtered before billing, and Credited Cost, refunded after a billing cycle closes. "We don't charge for invalid traffic, and our multi-layered defenses have always worked in the background," wrote Google's Keerat Sharma, adding that exposure to invalid leads fell by an average of 30% in 2026. PPC News Feed noted the gradual rollout. AdExchanger reported that a Google spokesperson said the systems "analyze all traffic, including agentic activity," and that the feature was built because advertisers complained about a lack of transparency.

The defaults kept moving towards automation. PPC Land reported that Google Ads Editor 2.14 turns on AI Max by default for new Search campaigns, with text asset automation and Final URL expansion also switched on, among ten new features Schwartz listed. The release adds account-level customer acquisition and retention settings and an "Only bid for lapsed customers" option, and Google now also lets advertisers bulk edit customer retention settings across campaigns, a change Bia Camargo spotted. Performance Max gained visual guidelines for AI-generated images, with up to three reference images and entries of 300 characters each.

Policy pages tightened. Google clarified that ads using AI to impersonate public figures are banned even when disclosed, and that violations mean suspension without warning. "Ads that impersonate public figures using AI aren't allowed, even if they disclose that they were generated or edited using AI," the policy now reads. A separate line bars targeting users based on an interest in categories prohibited on Google's ad network, such as counterfeit goods and dangerous products.

Sponsored results are testing new furniture. Sachin Patel spotted a "Found on site" label with a magnifying-glass icon and a "More pages" label below text ads, which Schwartz suspects is "a new sitelink asset of sorts." Developers lost a familiar address: Google's old Ads Developer Blog feed gets no new posts after November 10, as the blog moves from Blogger after 15 years and becomes the Google Advertising and Measurement Developer Blog. And Google Registry opened .eat, .fly and .here domains with an early-access surcharge until November 17, with Wingstop, Zillow and Rocket Lawyer among the first users.

Regulators tighten the screws

The most consequential privacy text of the day came from the European Data Protection Board. Its final guidelines on legitimate interest, adopted on November 10, say cross-site ad tracking will rarely pass the legitimate interest test, more than two years after the October 2024 draft. Personalised advertising counts as direct marketing, so objections succeed without balancing, and profiling children for marketing generally fails. For intrusive tracking, the guidelines say "the balancing test would be very unlikely to yield positive results." Across the Atlantic, the Red Iberoamericana de Proteccion de Datos said client data is off limits for vendors' AI training by default. "The mere indication that artificial intelligence or algorithms are used does not satisfy the duty to inform," it wrote.

Google's oldest EU fine may return. Advocate General Juliane Kokott advised the Court of Justice on November 12 that the General Court was wrong to scrap Google's EUR 1.49 billion AdSense fine. She called its demand for a contract-by-contract analysis "fundamentally mistaken" and found the clauses "were not only capable of producing exclusionary effects, but actually did so." The opinion is not binding.

Marketplaces and retailers faced their own regulators. Japan's Fair Trade Commission approved a plan under which Amazon Japan faces a five-year monitor over a rule that pegged sellers to rival prices for the Featured Offer slot. The FTC and 17 states reached a settlement under which Family Dollar faces a $63 million order over register prices above shelf tags, including a $40 million redress fund. "Over the last four years, we have paid at least three (3) million dollars in fines/penalties related to pricing," reads an internal company note quoted in the complaint.

Enforcement elsewhere was uneven. PPC Land found that a year after India fixed its Data Protection Board at four members, none has been appointed, even as consent managers must register with it from November 13. Italy's Garante, by contrast, issued a run of decisions: EUR 1.7 million against Wind Tre over breaches that exposed more than 365,000 customers, EUR 48,000 against Poste Italiane and EUR 33,000 against Deutsche Bank over the privacy notice for BancoPosta loans, and EUR 5,000 against fashion retailer Barbuti for marketing texts sent after an erasure request.

Broadcasters cut, streamers grow

Television's ad market weakened again. ITV said it is cutting GBP 30 million of fourth-quarter spending as TV ad revenue heads for a fall of up to 10%, against analyst expectations of a 1.8% decline. "Demand for advertising in H2 has weakened," said chief executive Carolyn McCall. In the US, iHeartMedia cut its 2026 profit forecast by up to $250 million, to adjusted EBITDA of $550 million to $600 million, and its shares fell 35% after hours. "This is one of the most uncertain periods in the advertising environment that we have managed through, including COVID-19," said president Rich Bressler. In Germany, ProSiebenSat.1's TV ad revenue fell 13% in the third quarter to EUR 261 million, which the company blamed on "a restrained willingness to invest in advertising, particularly in the TV sector."

Streaming kept absorbing the audience. Barb data showed Netflix's ad tier gained 800,000 UK homes in a quarter, reaching about 8.1 million, or 44% of Netflix homes, while HBO Max entered Barb's tracker at 3.1 million. Gracenote and Magnite agreed to package US streaming TV ads by what is on screen, building deals from Gracenote's graph of 58 million titles, with live sports the lead use case. Gracenote's own State of Play survey found that 78% of 18 to 24 year olds want a single streaming guide, up from 58%. "Viewers want one place to look, even when there are many places to watch," said chief business officer Ryan Moore. YouTube, meanwhile, moved a premium title out of advertisers' reach: it puts the LISA documentary Always Lalisa behind its Premium paywall on November 18.

Outdoor was the bright spot. Stroer said its digital billboard sales grew 11% while paper posters fell 4.4% in the third quarter. "Digital Out of Home remains the most important growth driver of our core business," said chief executive Udo Muller, who also cited the first meaningful orders from AI companies.

Commerce, retail media and the holiday rush

Amazon set its calendar. Black Friday Week runs from November 19 to 30 with nearly two weeks of themed deal drops, with deals dropping twice on Black Friday and Cyber Monday and Alexa for Shopping able to buy automatically when a target price is met. "Customers count on Amazon for low prices and great selection every day, not just during the holidays," said Doug Herrington, chief executive of Worldwide Amazon Stores. Amazon's Ring launched a $249.99 indoor drone that maps the home it patrols, without saying where floor plans are stored, and AWS opened its Chile cloud region to select customers, backed by more than $4 billion.

Amazon's ad console is being rebuilt underneath advertisers. Its Support Center now says unmigrated reports will be lost on January 31, 2027, a month later than first planned, with the old report pages going read-only on December 17. Of the 156 dimensions in unified reporting, 85 apply to Sponsored Products against 137 for DVA+. Agencies lose the legacy DVA fee setting after January 31, 2027 as manager-account fees move into open beta. PPC Land found that Amazon's 16 benchmark recommendations never suggest cutting budgets, and two suggest testing higher bids. Estimated KENP royalties have gone from Kindle authors' ad reports. Amazon also forced prediction markets through gambling ad verification, alongside casinos and sports betting, and added FBA lead time estimates warning that a shipment taking five days in January may take 12 at peak. Its studio arm set Michael B. Jordan's The Thomas Crown Affair for worldwide cinema release on March 5, 2027.

New media networks keep appearing. British Airways' parent IAG is launching IAG Media, combining advertising across British Airways, Aer Lingus, Iberia, Level and Vueling, which served about 122 million passengers in 2025. "We want to create one unified story of how IAG airlines are enhancing the passenger experience and our advertiser experience," said Josh Peckham, its chief commercial officer. Online pharmacy DocMorris said its ad unit dmr expects to double revenue to more than EUR 20 million in 2026, with 220 advertisers invoiced.

Shopping platforms added tools. Pinterest launched Compare in the US, putting similar products' prices and reviews side by side. "Pinterest is making sure that AI helps people to shop without taking the enjoyment of shopping away," the company said. TikTok Shop added Product Diagnosis, which gives US sellers up to ten reasons a product's sales fell against a benchmark of top performers it does not define.

Technology companies traded on partnerships and listings. Google will put Adobe Acrobat in Gmail and Drive file previews and bring Adobe's creative tools into AI Mode. Apple added five holiday games to Apple Arcade, all free of ads and in-app purchases. Alibaba won a waiver from giving shareholders guaranteed shares in its chip unit's IPO. And Criteo gains its first MSCI index seats, effective November 30, even as third-quarter revenue fell 11% to $416 million. Data and marketing technology companies reported stronger quarters. NIQ swung to a $35.8 million profit, its first since its July 2025 IPO, and announced data deals with Google's Shopping Graph, OpenAI and Similarweb. Zeta Global raised its 2026 revenue forecast to $1.855 billion after a 46% third-quarter jump. "No third party will ever have access to our Data Cloud," said chief executive David Steinberg.

Creators get commissioned like studios

The creator economy is professionalising its paperwork. The IAB moved to define creator "views" as 66% of industry leaders asked for a common standard, and will work with the Media Rating Council in 2027 on shared definitions of views, impressions, reach and watch time, in a market it expects to reach $44 billion this year. "Creator marketing has largely won the argument about whether it belongs in the marketing plan," said James Douglas of the IAB.

Brands are buying series rather than posts. Digiday reported on why brands like Anthropologie are commissioning creator-made shows: comedian Pooja Tripathi wrote Anthropologie's first micro comedy series, The Holiday Party, with 90-second episodes running from November 11 to 19. A mid-tier sponsored post starts at about $8,000 to $10,000, while a multi-episode series runs well into five figures. "Going viral is one thing but if that means reaching two million people who don't want to buy the product," warned producer Becky Rooney.

Not every creator gathering is thriving. Digiday found TwitchCon at a crossroads as creators question its value, citing costs above $3,000 and safety concerns. "I don't feel like we have a clear enough understanding of what TwitchCon is today," said Justin Miclat of Click Media and Kinetic Group. In sport, AdExchanger reported that marketers are writing a new playbook for women's sports, with RAJ Sports, owner of the Portland Thorns and Portland Fire, finding fans arrive through merchandise rather than tickets. "Nobody leaves, and I haven't seen that in men's sports," said chief commercial officer John Torris.

YouTube went big on one launch: GTA VI videos have drawn 40 billion views before the game's November 19 release, and the platform plans a 24-hour livestream. YouTube Studio now turns 16:9 podcast segments into vertical Shorts of up to three minutes. WHOOP launched WHOOP Humans, letting its 3 million members share health data with friends. "This is the most verifiably human network ever launched," said founder Will Ahmed. And Disney+ on Meta Quest gained more than 60 3D movies at no extra cost.

Holiday ads lean on feeling

The holiday campaigns that arrived on November 12 mostly sold emotion. Apple released "The Dreamer," a four-minute holiday film about the power of belief, directed by Melina Matsoukas and told without dialogue. Oreo released its first holiday ad in five years, made by Colin Jost's No Notes Productions, in which a cookie-stealing dad lands on Santa's naughty list. Shopify launched its first campaign with Mother, a "Just An Idea" platform following four would-be founders helped by its Sidekick assistant. And Talkspace recruited Michael Phelps for Men's Mental Health Awareness Month. "Rather than telling men why they should try therapy, we're letting other men show them what it actually looks like," said chief marketing officer Katelyn Watson.

In Britain, System1's early rankings showed supermarkets taking seven of the top 12 places among Christmas ads, with Morrisons and Sainsbury's tied at the top. "If the early leaders tell us anything, it's that Brits love an underdog," said Andrew Tindall of System1.

The day's two biggest stories pointed the same way. Nvidia's chips and Google's models are now so central to advertising that a change at the top of one company and a model upgrade at the other reshape everyone else's week. The rest of the industry is still trying to measure what these systems send its way, from invalid clicks to agent visits to AI referrals, and on November 12 it got a little more data and a lot more questions.
