The Turf War in Your Living Room
Welcome to the brawl behind your TV remote.
Forget polite earnings calls. The CTV war looks more like a parking-lot fight after last call. Roku’s the local bouncer gripping the U.S. market like a headlock, Samsung’s running the international airports like it’s Heathrow and Dubai combined, and Amazon? It’s the casino boss underground, digging tunnels that connect every device in your house until you realize they already own your living room.
And make no mistake: whoever wins doesn’t just control what you watch—they control the glass itself. And whoever owns the glass writes the rules: data, UI monetization, CPM inflation, all of it.
Roku: The Local Bouncer With a Chokehold
Roku’s at 37–39% U.S. share and it shows. They’ve turned “ease of use” into a business model, locking down households who don’t want to futz with menus and settings. From Roku City screensavers to Brand Studio banners and home-screen takeovers, they’re turning your interface into a casino floor—and charging brands table fees to get in.
And here’s where it gets spicy. In a conversation at CES, Roku’s PR team didn’t even blink: “We’re going to destroy Samsung. Nothing can stop us.” No hedging, no spin. Just flat-out certainty. If Samsung’s the international airport, Roku thinks it’s already got TSA locked in the basement.
The swagger isn’t totally unfounded—Roku is still the first stop for U.S. advertisers and keeps layering on data partnerships and UI monetization tricks. But that kind of chest-thumping usually means someone’s nervous.
Samsung: The Global Gatekeeper
While Roku flexes in the States, Samsung dominates abroad. With 33% in EMEA and deep penetration across APAC and the UK, Samsung doesn’t need to act scrappy. They’re the global gatekeeper: if you buy a TV in half the world, odds are it’s running Tizen.
At Cannes, Samsung Ads execs couldn’t stop hyping “Creative Canvas” and Samsung TV Plus—their free, ad-supported streaming service baked into 88 million+ sets. It autoplays when you boot the TV, meaning their MAUs are padded like a Kardashian photo shoot, but the sheer volume is still undeniable.
And don’t forget the ecosystem play: Samsung can sync mobile, tablet, and even fridge data. Yes, the same company that knows what show you watched last night might also know what you left in the crisper drawer.
Amazon: The Casino Boss Underground
Then there’s Amazon, the disruptor sitting at 17% U.S. share—for now. They’re not trying to win by inches. They’re tunneling under both Roku and Samsung, connecting Fire sticks, Prime Video, Twitch, MGM Studios, and their DSP until they own the pipes.
What makes them terrifying is identity. Amazon’s got 80 million logged-in U.S. households, the kind of authenticated reach everyone else is duct-taping together with third-party data. One agency insider put it bluntly: “If Amazon decides to take this market, the rest of us are just speed bumps.”
Why It Matters: Whoever Owns the Glass, Owns You
This isn’t a story about who ships more plastic remotes. It’s about who sets the CPMs, who bundles the data, and who gets to tax advertisers for showing up.
Roku’s glass: U.S. chokehold + UI ad monetization
Samsung’s glass: Global scale + baked-in FAST service
Amazon’s glass: Identity moat + DSP leverage
The winner doesn’t just sell ads. They decide the terms of trade for the next decade of television.
Where We Got the Receipts
Pixalate Q2 2025: Roku ~37% U.S./global, Samsung ~12% U.S., 33% EMEA, Amazon ~17% U.S.
Parks Associates “Future of Video”: Roku, Amazon Fire, Samsung Tizen = top three CTV platforms.
Cannes & CES convos: Samsung hyping Creative Canvas, Roku PR insisting they’ll “destroy Samsung.”
Agency chatter: Rising CPMs, UI monetization becoming a hidden tax.
The Cliffhanger
So the next time you grab your Roku remote, fire up Samsung TV Plus, or let Amazon auto-renew your Prime, remember: you’re not just picking a platform—you’re picking your cartel boss.
This is where the free floaties end. The money map lives in ADOTAT+.

The Rabbi of ROAS
Sidebar: One CEO’s Take
From the corner office of a top measurement firm, the view looks a little different:
Yes — the CTV operating systems have the leverage. They own the start screen, they mine ACR data, and they know more about the household than anyone else in the chain. That’s a structural power play.
But no — it’s not the showdown everyone frames as Roku vs. Samsung. Households are hybrid. A Roku in the den, a Samsung in the bedroom — nobody’s crowned king of the living room.
Where he points the spotlight — the ad marketplaces. DSPs and SSPs don’t split neatly; they consolidate. They tilt toward “winner-take-most.” And the one looming largest? Amazon. Its strategy is simple: squeeze where others have fat margins and turn inefficiency into opportunity.
ACR Is the Crown: Who Actually Owns the Eyes-On Map?
In connected television, the decisive advantage no longer lies in simply owning distribution or user interface real estate. The real crown jewel is Automatic Content Recognition (ACR). By linking what households are actually watching on the glass to identity graphs and commerce data, ACR provides the foundation for targeting power, pricing leverage, and ultimately, control of the market.
Roku: First-Party ACR and Hardware Integration
Roku has steadily expanded from software to hardware, embedding its operating system in a growing number of branded Roku TVs. That vertical integration allows it to collect ACR data directly from the screen, rather than relying on modeled or third-party estimates.
Closed-loop targeting: Roku connects ACR segments to retail partnerships, enabling outcome-based campaigns where advertisers can tie exposure directly to purchase.
Programmatic guardrails: Through integrations with The Trade Desk and other DSPs, Roku’s ACR signals help suppress ads to already-exposed households and manage campaign frequency.
Vertical edge: Verified co-viewing segments give categories like retail, auto, and pharma confidence that messaging is reaching entire households, not just individuals.
Samsung: Multinational Scale and Cross-Device Reach
Samsung’s ACR footprint spans more than 70 million devices in Europe alone, with particularly high penetration in the UK. Unlike Roku’s U.S.-heavy base, Samsung’s advantage is breadth and cross-device linkages.
Programmatic activation: Samsung TV Plus inventory, available through major DSPs, is enriched with ACR-based audience segments.
Cross-screen targeting: By linking TV and mobile devices under the Samsung umbrella, the company enables advertisers to reach households with greater precision across screens.
Regional strength: For advertisers seeking scale in EMEA and APAC, Samsung’s density positions it as the most comprehensive source of verified TV viewing data.
Amazon: Prime Identity and Fire OS Graphs
Amazon approaches ACR differently, leveraging its Fire TV OS footprint and tying it directly to Prime accounts. The result is an authenticated household graph that merges viewing behavior with shopping and browsing data.
Authenticated reach: Advertisers can access more than 80 million logged-in households in the U.S., with consistently high match rates.
DSP leverage: Amazon’s DSP combines ACR signals with commerce and streaming data, enabling precise targeting and closed-loop attribution.
New inventory: With Netflix placements entering the Amazon DSP, authenticated reach is quickly becoming a de facto premium tier in CTV buying.
Buyer Takeaway: ACR + Identity = Pricing Power
ACR data, paired with logged-in identity, is the mechanism by which platforms now set pricing and dictate addressability. Impressions verified by ACR command premiums because they confirm real “eyes-on.” Inferred or modeled segments, by contrast, will increasingly be discounted.
For advertisers, this means:
Audit every buy: What percentage of impressions are ACR-verified versus inferred?
Set thresholds: Demand minimum ACR verification floors in IOs; negotiate make-goods if missed.
Prioritize vertical lift: Retail, auto, and pharma stand to benefit most from verified co-viewing data, where purchase decisions are made at the household level.
Summary Table: ACR Ownership and Activation
Platform | ACR Scale | Regional Strength | Identity Link | Vertical Advantage |
---|---|---|---|---|
Roku | 70M+ TVs (incl. Roku OS) | U.S./LATAM | Roku login + retail tie-outs | DTC, retail media, outcome-based shoppable TV |
Samsung | 70M+ in EU; UK density | EMEA/APAC | Device + mobile graph | Incremental reach, pharma, household co-viewing |
Amazon | 80M+ authenticated HHs | U.S./Global | Prime login + purchase graph | CPG, auto, precise closed-loop attribution |
Playbook: Guardrails for Advertisers
Audit verification: Demand full reporting on ACR-verified impressions.
Set a floor: Establish a minimum % of ACR-verified delivery for premium buys.
Vertical precision: For retail, auto, and pharma, direct spend to platforms with the strongest ACR + identity linkage to capture genuine incremental lift.
ACR has become the coin of the realm in CTV. Platforms that can prove “eyes-on” with authenticated identity will not only command higher CPMs but also shape the rules of measurement, accountability, and budget allocation for the entire industry.
The free tier? Cute. You get the jokes, the hairball metaphors, the swagger quotes from CES. But the real game is happening in ADOTAT+, and here’s what you’re not seeing:
The receipts. Which platforms are bundling UI with video and calling it “efficiency.”
The contracts. IO clauses you should be inserting to stop the “Performance+” shell game that sneaks in remarketing.
The ladders. How to structure NFL Sundays and holiday tentpoles without blowing half your Q4 budget on one screen.
The arbitrage. When to actually pay Samsung’s EMEA premium, and when Roku’s U.S. chokehold is the smarter bet.
The math. Attentive eCPM ladders that reveal whether you’re buying memory or wallpaper.
And here’s the kicker: only right now, we’re offering 20% off for life.
Not three months. Not until Q1. For life.
Once it’s gone, it’s gone — and when the 2026 price hike hits, you’ll be stuck paying double while ADOTAT+ lifers laugh all the way to the QBR.
