Cannes used to be the place where agency execs toasted to “innovative storytelling” while pretending not to care how many zeroes were on the yacht rental. The biggest stress was whether someone wore white linen too early in the week. But that was a different era — back when digital video was still a side dish and TV was linear, boring, and mostly bought over steak dinners.

Now? Cannes smells less like rosé and more like war rooms. The new currency is ACR data. The new power move is owning the home screen. And the new question haunting every brand, publisher, and retail media buyer is simple:

Who controls the living room — and by extension, the future of advertising?

Spoiler: It’s not Netflix. And it sure as hell isn’t your media agency.

You think your living room is a sanctuary — a sacred space for watching prestige TV, yelling at the news, or letting Bluey raise your children. But to LG, Samsung, and the Walmart-Vizio alliance, your living room is a warzone. It’s the last “unclaimed” screen, and every major OEM wants to own it — not just with hardware, but with the software, the ads, the commerce layer, and the downstream data streams that keep your household running.

What was once a dumb slab of plastic is now the command center of the home — controlling what you see, what you buy, what you binge, and even what you pause to make dinner. And if you think the screen on your wall isn’t influencing your behavior in the same way your phone does? Congrats — you’re already a target, not a user.

Here’s the quiet part no one says out loud on mainstage panels: They don’t want to sell you TVs anymore. They want to sell you everything through the TV.

LG isn’t interested in just being the brand you bought at Best Buy. It wants to be your content concierge, ad curator, and shoppable inspiration board.
Samsung sees your screen as a programmatic superhighway — optimized for real-time reach, custom segments, and maybe even refrigerator-integrated ads (yes, they make those too).
And Walmart? They didn’t pay $2.3 billion for Vizio because they suddenly care about picture quality. They wanted a direct line from ad impression to purchase — and your remote control is the new checkout button.

Let’s call it what it is: a Trojan horse war.
Your TV is the horse. You invited it in.
Now they’re storming the gates of your attention, your wallet, and your household data — all while selling you 30-second ads dressed as “enhanced experiences.”

This isn’t a beauty pageant about who makes the sexiest screen. It’s an arms race of ecosystem economics. Each of these players has a different strategy — but all are fighting for the same thing: persistent, scalable, opt-in access to your home life.

LG is pushing webOS as a design-forward operating system wrapped in premium creative formats. Think Apple meets Hollywood, with 3D ad units and “art + science” sales decks that speak to brand marketers dreaming of Cannes Lions. Their pitch is elegance — a curated platform where every pause ad and home screen slot feels intentional and elevated.

Samsung, by contrast, is building a global broadcast infrastructure with Tizen OS and Samsung TV Plus. They talk like a telecom and execute like Amazon. With 250+ FAST channels, their home screen has turned into a juggernaut — scaled, measured, and now shoppable. They’re not worried about artistry. They’re here to dominate reach, frequency, and measurement.

Vizio/Walmart are deploying the bluntest instrument of all: commerce. By combining SmartCast’s OS with Walmart Connect’s retail muscle, they’re collapsing the funnel into one tap. From Unilever to CPG to auto, they’re selling something that few others can: full-funnel outcomes, with your product sitting one click away from the ad that just played on someone’s screen.

Connected TV isn’t the future — it’s the now. And it’s bigger than we’re pretending. With ad-supported streaming exploding and traditional cable fading like a tan line in February, the screen wars aren’t about content anymore. They’re about:

CTV ad spend is projected to hit over $30 billion in the U.S. alone next year — but that’s just table stakes. The real prize is access to the transaction layer. Whoever owns that owns not just media — they own commerce infrastructure. And once that happens, expect the lines between advertiser, publisher, retailer, and device maker to completely dissolve.

This isn’t about CPMs.
It’s about closed-loop dominance.

Each is building its own operating system. Each has its own data moat. Each is racing to be the central nervous system of your household.

And none of them are stopping at just the screen. From mobile integration to fridge screens to full-blown retail analytics, the TV is just the start.

This isn’t a product comparison.
This is a platform war — with stakes higher than your HBO subscription.

The players don’t want to “partner.” They want to own.
And your living room? It’s the next operating system.

Who wins? Too early to tell.
But one thing’s clear:
The TV may be smart — but the companies behind it are ruthless.

In the rapidly converging world of connected television (CTV), the clash between Samsung and LG is not just a matter of market share—it’s a deep philosophical divergence over what the screen in your living room should become. On paper, both companies are dominant TV manufacturers with global reach, proprietary operating systems, and increasingly sophisticated advertising businesses. But behind the logos lies a profound contrast in how each views its role in the future of media, commerce, and consumer interaction.

One leads with scale and precision infrastructure. The other with creative innovation and human-centric storytelling.

Welcome to the quiet war behind your remote control.

If connected TV were a land grab, Samsung is the railroad baron—laying track fast, wide, and with relentless efficiency. With 67.8 million smart TVs in U.S. homes, Samsung has quietly captured nearly half of the domestic market. This reach gives it the largest footprint of any OEM by a wide margin—enough to turn its platform into a must-buy for brands seeking ubiquitous household penetration.

This scale is the foundation of Samsung’s platform ambition: Tizen OS, a proprietary operating system layered across its devices, powers everything from app discovery to Samsung’s own FAST service, Samsung TV Plus. That platform alone now delivers over 250 linear streaming channels, turning the TV into a dynamic advertising endpoint—not just for entertainment, but for commerce, awareness, and engagement.

Samsung’s strategy is ecosystem-first, where every feature—ACR, AI, even its refrigerator screens—is designed to generate data, enhance targeting, and optimize ad delivery. Its infrastructure runs deep, tapping into first-party behavioral datasets, probabilistic audience graphs, and machine learning systems that identify viewing patterns across devices and environments.

But don’t mistake efficiency for elegance. Samsung doesn’t pretend to be a storytelling brand. Its value proposition is performance, not poetry. It rarely courts advertisers with Cannes-friendly jargon or bespoke campaign case studies. Instead, it promises raw power: automated media planning, predictive segmentation, dynamic creative optimization (DCO), and, most importantly, scale that can’t be ignored.

Where Samsung operates like Amazon in a suit, LG has positioned itself as the Apple of CTV—elegant, curated, and proudly less mass-market in its approach. With a smaller footprint (roughly half the U.S. market share of Samsung), LG plays a different game altogether: quality of interaction over quantity of impressions.

At the center of LG’s strategy is webOS, a sleek, customizable interface that prioritizes user experience and advertiser creativity. Unlike Samsung’s volume-first FAST model, LG focuses on direct-to-glass innovation: native ad units, premium home screen takeovers, and visually stunning formats such as 3D-rendered ads that seem to extend beyond the screen itself.

The message is clear: LG doesn’t want to flood your living room with inventory. It wants to shape your living room experience, using data and design to deliver ads that feel personalized, elevated, and—in some cases—artful.

Behind this approach is a consultative ad operation more akin to a boutique agency than a technology provider. LG works directly with brands to co-develop custom ad creatives, leverages AI to resize or reformat assets for its canvas, and uses emotional segmentation—via partners like Zenaps—to align messages with viewer mindset and content tone. Their Cannes pitch isn’t about reach. It’s about resonance.

Both Samsung and LG are heavy investors in Automatic Content Recognition (ACR) technology, the foundation of modern TV targeting and measurement. But even here, their philosophical divergence shows.

Samsung’s ACR is a data harvesting engine—technical, precise, and calibrated for scale. It feeds anonymized signals into multi-domain ML models that power everything from ad targeting to viewership analytics. The company’s emphasis is on cross-platform attribution, campaign reach, and “optimal frequency” scoring. AI, in Samsung’s world, is a tactical tool—not a marketing story.

LG, by contrast, frames its AI capabilities in human terms. Their ACR isn’t just about measurement—it’s about controlling frequency saturation, understanding emotional cadence, and using data to inform creative sequencing. Their use of generative AI tools extends into production, dynamic design, and campaign intelligence. They don’t just use AI—they narrate it, wrapping it in language advertisers understand: “insight,” “intimacy,” “craft.”

Put simply: Samsung builds for machines; LG builds with humans in mind.

At a glance, both brands offer similar capabilities: content discovery interfaces, personalized recommendations, and programmatic monetization. But under the hood, they’ve taken very different routes to the home screen:

Samsung treats the home screen as a mass media real estate: scalable, monetizable, and tightly optimized for performance. Its goal is to mirror YouTube or Roku—high CPMs delivered at relentless volume.

LG views it as a creative medium—one that can host brand stories, immersive campaigns, and next-gen ad formats that mirror experiential design. To LG, the home screen isn’t a billboard. It’s a blank canvas.

Both platforms employ machine learning extensively—but only one talks about it like a selling point.

Samsung's ML runs behind the scenes: powering AI upscaling, ACR segmentation, and reach modeling. It's integrated deeply, invisibly, and efficiently. There’s little effort to make it user-facing. It’s simply assumed to work.

LG, on the other hand, markets its ML use like a feature. It showcases personalized recommendations via Voice ID, contextual search tools via AI Concierge, and its Alpha 11 chip's deep learning capabilities for real-time image enhancement. In advertising, LG positions its ML tools as creative companions, not just targeting engines—offering brand marketers insight into not just who their audience is, but why they engage.

Samsung and LG may both be “smart TV” companies, but their strategic worldviews could not be more different. Samsung is a data infrastructure juggernaut—efficient, sprawling, and focused on total media consolidation. LG is a creative ecosystem architect—smaller, slower, but obsessively focused on experience, curation, and brand value.

To advertisers, the decision comes down to intent:

Both are vying to own the living room.
Only one is trying to make you fall in love with it.

If you've been reading our free coverage—like the breakdown of LG’s immersive ad philosophy or Walmart/Vizio’s commerce-first conquest—you’ve already seen how ADOTAT cuts through press release noise and actually analyzes the adtech war for your living room. We’re not here to rehash earnings calls. We’re here to interpret them.

But if you’re not a paid subscriber yet, here’s what you’re missing:

ADOTAT+ isn’t backed by holding companies or underwritten by DSPs. We don’t sell media. We don’t accept pay-for-play interviews. We write what others are afraid to, because we answer only to one group: readers who actually care about the truth.

If you found value in our LG vs. Walmart/Vizio showdown—if it helped you think differently about platform strategy, media planning, or adtech innovation—then we need your support.

Because telling the full story—the one that isn’t shaped by PR handlers or proxy metrics—takes time, resources, and an absolute refusal to play by the industry’s “everyone’s a winner” rulebook.

So here’s the pitch:

Stay Bold. Stay Curious. Know More Than You Did Yesterday.
