Let's just get the ground rules out of the way up top.

Adotat is not in the business of promoting companies. We are not in the business of retyping press releases and sticking a byline on top like a participation ribbon. We are in the business of telling you who owns what, who paid what, and who benefits from the story you are reading. Then you, the adult, the one with the checkbook and the media plan and the CFO breathing down your neck, figure out what it means.

This has not made us popular. People are angry. This publication has been threatened. We have been attacked, sometimes by outlets that have financial relationships with Nielsen's competitors through their corporate siblings. That bothers us. We are not going to elaborate further in this piece, because our standards for naming people in print are higher than their standards for attacking us. But we want you to know we noticed. We are taking notes. And when the pushback to accurate reporting is "you shouldn't be writing this" instead of "your facts are wrong," you are, by definition, writing the right thing.

One piece of housekeeping before we start. Last week's reporting here included a line characterizing Nielsen's streaming meter as "bolted on, ship it, good enough." Nielsen responded directly. The streaming meter has been in testing since 2015, went through a formal MRC accreditation process, and is not something Nielsen rushed out the door. That line was wrong. We are correcting it. That is what happens at a publication that cares about being right. Onward.

For two years now, the trade press has been running a slow-motion demolition job on Nielsen. Nielsen is "legacy." Nielsen is "broken." Nielsen is a "70-year monopoly" finally, at long last, being disrupted by a brave little band of AI-powered, big-data, cross-screen, outcomes-native, multi-currency, [insert-buzzword-here] upstarts riding in on horseback to rescue television from a company whose terrible, embarrassing sin is measuring audiences using a panel, plus tens of millions of set-top boxes, plus ACR data from smart TVs. The horror. Someone call the authorities.

Here is the part nobody writes. The upstarts are not upstarts. They are billion-dollar-funded portfolio companies of some of the most aggressive private equity and hedge fund investors on planet earth, and those investors have exits to generate. Exits that, in a coincidence so stunning the trade press never quite notices it, require the trade press to keep writing exactly the kind of stories the trade press keeps writing.

Let's do real numbers.

VideoAmp raised a $275 million Series F in October 2021 at a valuation somewhere around $1.1 to $1.4 billion. Then a $150 million round led by Vista Credit Partners in late 2023. Plus earlier rounds. The cap table reads like a guest list at a Hamptons fundraiser: Tiger Global. Spruce House Partnership. D1 Capital. Ankona Capital. EPIQ Capital. Vista. Vista Credit, by the way, is not in the business of funding methodology debates for the love of the game. Vista Credit is in the business of financing enterprise technology and generating returns for limited partners on a clock. The clock is ticking. Has been since 2023.

iSpot.tv has taken roughly $58 million in earlier venture, plus a $325 million minority investment from Goldman Sachs Asset Management in 2022. Goldman's adjacent portfolio includes TransUnion, Innovid, GumGum, and HUMAN. Read that list twice. Adtech. Adtech. Adtech. Adtech. Goldman is not a measurement investor. Goldman is an adtech portfolio operator running an ecosystem bet across identity, verification, and measurement-adjacent vendors whose economics materially improve the moment the currency layer of television gets split into three or four pieces instead of one.

Comscore is the different case, and it deserves its own treatment, because lumping it in with the others would be lazy and, worse, inaccurate.

Comscore is publicly traded. Its capital structure is not a private equity exit thesis. It is an actual public company, which means its decisions show up in filings, its leadership changes are documented, and its progress or lack of progress happens on a clock visible to anyone with a Yahoo Finance tab open. That is a different posture from the PE-backed challengers, and readers deserve the distinction.

Comscore has been through a rough decade. An earlier leadership era ended badly, with an SEC settlement in 2019 involving the prior CEO, a roughly $50 million revenue overstatement, and the governance fallout that follows that kind of event. That was six years ago. None of the people responsible are at the company anymore. Current leadership has, by all accounts we can find, genuinely moved on. The matter is settled, the cleanup has been done, and pretending otherwise in 2026 would be unfair. Adotat's job is not to hang a 2019 scandal around a 2026 leadership team's neck. That is what the trade press does to Nielsen every time it reports on a 2022 methodology dispute, and we are not going to do the same thing in reverse.

So let's talk about Comscore as it actually is right now.

Comscore has scoped MRC accreditations in digital and local household tuning, and the company works with the MRC on additional accreditations as appropriate. It is also JIC-certified as a national cross-platform currency. Its flagship national person-level TV accreditation is not where Nielsen's Big Data + Panel accreditation sits, and that is a real distinction that buyers should understand, but it is also a work in progress rather than a scandal.

On methodology: like every modern big-data measurement company, Comscore receives data at the household level and personifies it using a combination of third-party and proprietary data sets. This is standard across the industry. You cannot do person-level measurement from ACR or set-top box data without some form of personification model, because television sets do not, regrettably, come with birth certificates. Comscore tells us they are confident in the stability and transactability of both their household and their persons-level data, and they are happy to have clients compare their numbers to anyone else's. Fair enough. That is the correct posture for a measurement company to take.

Strategically, Comscore has been clear about where it is going, and this is where the company's messaging has actually been among the most honest in the category. Comscore does not claim it will be the single currency of the future. It says, more or less directly, that the days of a single currency dominating for generations are probably over, and that other measurement sources will be part of the mix for most clients. That is not a dodge. That is a sober read of the market. It is also a meaningfully different posture from the "we are the replacement" positioning being sold by certain PE-backed competitors, and readers should notice the difference.

Where Comscore has actual traction worth crediting: theatrical, digital audience ranking via Media Metrix, and local TV. These are real strengths with real client adoption. More recently, Comscore launched a product called Comscore Content Measurement, which delivers cross-platform deduplicated reach for a given piece of content across linear and streaming. The interesting use case, and it is legitimately interesting, is comparative audience analysis: if a brand is advertising against basketball games on linear and CTV, what does a well-known basketball creator on YouTube add to the incremental reach? That is a useful question, and it is not a question Nielsen is built to answer in the same way. The response from clients, per Comscore, has been strong. We have no reason to doubt them.

Comscore is also doing interesting work measuring AI tool usage. Not just who is using ChatGPT or Claude or Perplexity or Gemini, but how consumers use those tools, whose content gets cited in AI-generated results, and how often users follow the citation links back to source material. In an industry where AI search is genuinely starting to reshape commerce and discovery, having a panel-based view into actual consumer behavior inside these tools is a real product, not a buzzword play. Credit where credit is due.

The company's 12-to-24-month focus, per current leadership, is modern measurement across linear, digital, social, CTV, creators, and AI, and pulling it all together so advertisers can optimize for the world they actually live in. That is a coherent strategy. It is narrower and more focused than the "we are going to dethrone Nielsen" maximalism that characterized an earlier era of Comscore positioning, and honestly, it reads better for it.

So where does that leave Comscore in the story?

Not in the same bucket as VideoAmp and iSpot. The capital structure is different, the public-company discipline is different, and the current strategic messaging is meaningfully more grounded. Comscore is the challenger with their shit together in a way the others aren't currently demonstrating. They have genuine product wins, they are not trying to sell a fantasy about single-handedly replacing Nielsen, and the leadership team is doing the unsexy work of building scoped, defensible product lines rather than screaming "the incumbent is dead" at every available microphone.

That said, the reader should still know that Comscore, like any public company, has investors who would prefer higher revenue. Every time "Nielsen is broken" becomes the industry narrative, every measurement alternative benefits, Comscore included. That is not an accusation. That is just how the incentive landscape works. We tell you the incentive landscape. You decide how much weight to give it.

Fair? We think so.

This is the single dumbest recurring error in modern television trade coverage, and it has been repeated in virtually every piece written about Nielsen for the last eight months. So let me explain it one more time, slowly, using small words.

The Gauge is a free monthly infographic. It shows usage share. Broadcast, cable, streaming, other. It exists so cable news producers have something to wave at viewers and so LinkedIn commentators have something to dunk on. That is what The Gauge is. That is what The Gauge has always been.

Big Data + Panel is the currency. It is the MRC-accredited, person-level, hybrid panel-plus-big-data product that actually settles billions of dollars of advertising transactions. It uses a person panel of more than 42,000 homes and 100,000 people, combined with set-top box and smart TV data covering 45 million households and 75 million devices. It is, in the description of the Media Rating Council itself, the first accredited hybrid person-level big-data TV currency.

When Nielsen paused methodology changes to the Gauge earlier this year, the currency ratings never stopped. Not for a day. Not for an hour. Every dollar of advertising transacted in that window transacted on Big Data + Panel, exactly as before. The Gauge pause was about a free marketing graphic.

The trade press conflated these two products, over and over and over, until industry veterans were genuinely confused about what had been paused, what had been accredited, and what had even happened. That is either journalistic malpractice or it is something worse. Not our job to figure out which. Your job to notice.

Here is the part the "Nielsen is dead" crowd would really prefer you skipped.

The Media Rating Council has fully accredited Nielsen's Big Data + Panel at the national TV level. The MRC went further, accrediting the integration of first-party live streaming data, making Big Data + Panel the first accredited measurement product to hit that standard. That is not a Nielsen press release. That is a signed audit decision from the industry's independent self-regulatory body, chaired by George Ivie, whose board includes representatives from across the ad and media ecosystem.

In 2026, the MRC instructed Nielsen to implement four specific enhancements: independent broadcast and cable estimates, demographic stability improvements, better Hispanic and Spanish-language segments, and simplified weighting. And the MRC explicitly noted, in its own language, that these changes would be disruptive to marketplace processes. It did not say Nielsen was wrong. It did not say Nielsen should be replaced. It said Nielsen was accredited, that the product would be improved, and that the improvements would be uncomfortable during the transition.

Read that again. The worst thing the independent auditor has said about Nielsen in 2026 is, essentially, "please upgrade, but please know this will hurt a little." That is not the language of a failing product. That is the language of a functioning, accredited, continuously-evolving measurement system.

Even the Video Advertising Bureau, the trade group funded in part by Nielsen's actual competitors, whose most aggressive 2026 analyses called Big Data + Panel "unstable" and "decimating demographics," conceded in the same breath that Big Data + Panel was already being used for upfront trading. Their ask was not for replacing Nielsen. Their ask was for parallel panel-only reporting alongside the new currency to ease the transition.

This is the distinction the trade press keeps quietly erasing: transition pain is not epistemic failure. A product that the MRC accredits and orders improved is not a broken product. It is an evolving product. The trade press knows the difference. The trade press is choosing not to explain it.

In finance, there is a concept called revealed preference. It means: forget what people say, look at what they do.

So let us look at what people actually do.

Challenger-friendly trade coverage itself has repeatedly pegged Nielsen's share of U.S. TV currency transactions somewhere between 80 and 90 percent in 2026. Nielsen itself will not stand behind a specific number, because they cannot track every dollar of every transaction across every measurement provider, and that is the correct posture. But even at the low end of the range, we are talking about the overwhelming majority of all television ad dollars in the United States still transacting on Nielsen. After two years of "Nielsen is dead" takes. After more than a billion dollars of private equity funding pushing alternative currencies. After OpenAP certifications. After JIC certifications. After every speech at every upfront.

If you want the most devastating single data point on this question, it did not come from Nielsen. It came from VideoAmp's own chairman, Peter Liguori, speaking at the CIMM 14th Annual Industry Summit. Let me quote him directly:

"You all spend $4 billion roughly on measurement services ... and for VideoAmp, we represent less than 1% of that TAM, so we're probably doing something wrong."

Sit with that for a second. Under 1% of the measurement TAM. Not our number. Not Nielsen's number. The number VideoAmp's own chairman stood up in front of an industry audience and admitted. After hundreds of millions of dollars in funding. After two years of sustained "alternative currency" marketing. After all the trade press coverage. Less than one percent.

Liguori is an honest guy and gave an honest answer. Good for him. The question the rest of us should be asking is how that answer squares with an entire trade press narrative about Nielsen's impending collapse.

Big Data + Panel was adopted by the vast majority of major broadcasters and agencies for the 2025 upfront, and the 2025-26 season is the first full broadcast and NFL season transacting on it. Networks that were publicly accusing Nielsen of "devaluing" them eighteen months ago are quietly renewing multi-year deals. In just the last few months, Nielsen has signed new multi-year deals with Paramount, Warner Bros. Discovery, TelevisaUnivision, Roku, and Tubi. Seven of the largest agencies, six of them major ad holding companies, plus one of the world's largest advertisers, recently renewed long-term Big Data + Panel partnerships.

On the advanced audience side, the pace is, if anything, faster. IPG Acxiom signed in March 2025. WPP Media in August 2025. Horizon Media in December 2025. In February 2026, Scarborough, Nielsen's consumer insights arm, added over 200 new advanced audience segments. These are the biggest holding companies on earth voluntarily committing multi-year paper to Nielsen's currency product during a period the trade press keeps telling us is the company's death spiral.

Networks, on the record, agree. Fox Sports' Mike Mulvihill, the man who runs insights and analytics for one of the largest sports media businesses in the country, told Sports Business Journal: "We certainly continue to see Nielsen as the gold standard in measurement, the currency of the business, the language that we should all be speaking." In a separate interview, Mulvihill went further: "Nielsen takes a lot of criticism in this business, but you have to give them credit for the fact that through their rollout of out-of-home measurement, the scorekeeping in this business has finally caught up to the reality."

The NFL's chief data and analytics officer, Paul Ballew, told The Wrap: "The measurement movement that Nielsen has taken to go to Big Data + Panel is something we strongly support." Not tolerated. Not reluctantly accepted. Strongly supported. The NFL. The single most valuable sports property in American television.

Off the record, it is even more direct. Fox told us last week what every network tells us. They get pitched by Nielsen competitors more than ever. The pitches arrive constantly. Most of them are junk. Most of the pitching vendors cannot actually do the work at scale. Most of it is AI-flavored vaporware wrapped in a Figma deck. Nielsen works the best. Every network says this, every time, once the tape recorder is off. They prefer it. They use it. They renew it. They do not care what you think, they do not care what the latest LinkedIn influencer posts, and they do not care what the trade press keeps screaming.

On the consumer side, Awful Announcing, covering the Netflix-MLB deal for its sports readership, wrote the quiet part plainly: "Nielsen remains the gold standard by which networks and advertisers do business, so having Nielsen-rated MLB games should give advertisers more confidence when buying inventory on Netflix."

Which brings us to the detail the trade press absolutely, categorically, refuses to lead with:

Netflix signed with Nielsen to measure MLB games in 2026.

Netflix. The streamer that was supposedly the leading edge of Nielsen's obsolescence. Signed. With Nielsen. For its highest-profile, most expensive, most ad-critical live sports rollout. Where is that front page? Where is the "streamers return to Nielsen" thinkpiece? Where is the acknowledgment that maybe, just maybe, when a streaming giant puts its actual money on the line for its biggest live sports bet of the decade, it wants an accredited incumbent and not a pitch deck?

I'll wait.

I will wait a long time. Because it is not coming.

While the trade press has been busy composing obituaries, Nielsen has been busy shipping product.

Big Data + Panel has been the industry's currency since the fall 2025 TV season. Not pilot. Not experimental. Currency. Every upfront deal of any size is settling on it.

Out of Home measurement expanded in 2025 to cover the entire United States. Every bar, every restaurant, every gym, every group viewing. This is the expansion that produced what sportswriters correctly described as "historic viewership figures" across college football, the NFL, and, most recently, the NCAA men's basketball tournament. When you start counting every person actually watching, you get bigger numbers. Which, it turns out, everyone wanted. Who knew.

Co-viewing pilot announced in early 2026, with the goal of inclusion in currency for the fall 2026 season. The next piece of the puzzle, shipping on schedule.

Outcomes Marketplace launched with Realeyes in July 2025 and expanded via Adelaide integration in October. Attention and outcomes, layered directly on top of reach and frequency, because that is what the CFOs are asking for. Additional integrations coming through 2026.

Scarborough's 200+ new advanced audience segments, launched in February 2026, ahead of the upfronts. Not vaporware. Not a deck. Actual product that holding companies are already plugging into.

Every major sports league has a Nielsen deal. Every one. Plus, again, because it deserves repeating, Netflix-MLB in 2026.

This is not a company keeping the lights on. This is a company building.

Let's end where we started.

Adotat's job is not to tell you Nielsen is perfect. Nielsen has communication problems. Nielsen's client messaging around DASH and the Gauge earlier this year was genuinely clumsy. The MRC's habit of governing by LinkedIn comment thread is an embarrassment to an industry self-regulatory body. Nielsen has real work to do on the four enhancements the MRC ordered in 2026, and on client transparency generally. These are all real.

But "Nielsen has real work to do" and "Nielsen is obsolete and about to be replaced" are two completely different sentences. The trade press keeps publishing the second one while the evidence, the accreditations, the contracts, the Netflix-MLB deal, the NFL and Fox Sports endorsements, the 80-to-90-percent share, and the spectacle of a challenger chairman conceding under 1% of the TAM, all point overwhelmingly to the first.

Our job is to tell you who owns what, who paid what, and who benefits from the story you are reading. We have done that. What you do with the information is your call.

Everything above is the public autopsy. What's below is the stuff we can't put on the open web:

The named investor deck laying out the fragmentation thesis in writing. The two renewal figures nobody at the upfronts would put on a slide. The off-record quote from a holdco measurement lead about what actually killed the JIC pitch inside their shop. And the short list of alt-currency vendors quietly shopping themselves before the music stops.

It's eight hundred words. It's sitting right there. You are one click from it.

Free readers, this is where we part ways for today. See you next issue.

Part 2 goes where Part 1 could not.

We go under the hood of MRC accreditation and show you which challengers do and do not have it, and at what scale. The answer is going to surprise exactly nobody who has been paying attention, but the specifics are damning.

We take Evan Shapiro seriously, because he deserves to be taken seriously. He has a real audience and a real point of view, and some of his critiques of the MRC are correct. We also show, line by line, where he is conflating products, confusing methodology with communication, and letting his walled-garden-skeptic instincts lead him into an argument that quietly ends up being pro-walled-garden.

We map the portfolio cross-connections across Vista, Tiger, D1, Goldman, and Insight, and show how the "alternative currency" thesis is not an innovation argument, it is an ecosystem bet that benefits specific portfolio clusters.

We explain the EDO case. One measurement company of comparable funding stage has taken a pointedly different approach toward Nielsen, for reasons that have everything to do with positioning and almost nothing to do with methodology. EDO is the experiment that exposes what the whole field is actually about.

Part 2 is behind the paywall where it belongs, because this kind of reporting costs real money, most of it paid to lawyers who read everything twice.
