Google TV and Android TV together now run on 300 million active devices globally, according to 9to5Google's reporting from I/O. The Google TV 300 million active devices figure is real. It is also the kind of number that looks better in a press release than it does under scrutiny.
The milestone tells you about the installed base Google has accumulated over years of OEM partnerships. It does not tell you much about where the platform is heading. For that, you need shipment-share data, and those numbers tell a different story. The core argument here is specific: Google TV's growth has slowed because the TV OS market is shifting toward proprietary platforms owned by manufacturers and retailers, and that shift is structural.
Two measures matter here, and they do not always point in the same direction. Active-device counts reflect accumulated historical installs still in use. Shipment-share forecasts reflect what hardware is selling now. This piece uses both, because each tells a different part of the story: one about the base Google has built, the other about the direction things are moving.
Google TV growth stalls: what the active-device numbers actually signal
The pace of active-device growth has dropped by roughly 75% compared to the prior comparable period. Going from 150 million to 270 million devices took about a year and a half, representing 80% growth. The jump from 270 million to 300 million devices covered a similar span of time but added just 30 million devices, growing at just over 11%. Those are sharply different trajectories.
The divergence between OEM momentum and platform momentum is the first concrete sign something has changed. TCL, one of Google TV's most consequential hardware partners, grew its global TV shipments 20% year-over-year in 2025, moving from 13% of the global TV market in 2024 to 16%, nearly matching Samsung's 17%, per Counterpoint Research data. TCL's hardware surge has not translated into a comparable acceleration in Google TV's disclosed active-device count. One of Google TV's fastest-growing hardware partners is expanding rapidly, and the platform's active-device growth is barely registering it.
To understand why, it helps to remember how Google TV grew in the first place. The platform expanded because brands like Hisense and TCL were moving away from in-house platforms, choosing to license Google's OS instead of maintaining their own. The current slowdown is partly a reversal of that logic. Hisense is now putting more weight behind VIDAA, its proprietary platform, rather than deepening its Google TV commitment. That reversal is not incidental. It reflects a change in what OEMs believe the software layer is worth to them, and to whom.
A platform growing at 11% while one of its primary hardware partners grows at 20% suggests the relationship between OEM scale and Google TV momentum has fundamentally weakened. That gap does not close on its own.
Where the numbers are slipping: Europe, North America, and the OEM defection pattern
Europe is Google TV's strongest developed market. Even there, the platform appears to have passed its peak.
Omdia data shows Google TV overtook Samsung's Tizen to become Europe's largest smart TV platform, reaching just under 33% share in 2024, while Tizen slid from near-35% dominance to under 25% in less than five years, 9to5Google reported. That was the high-water mark. The European share slipped below 32% in 2025 and is projected to fall under 31% this year.
The share losses are not going to Samsung. Tizen is expected to plateau at around 23% of the European market. The beneficiaries are VIDAA, Titan OS, TiVo OS, Fire TV, and Roku, a fragmented group of challengers, none individually large, but collectively trimming Google TV's lead. Philips' decision to switch from Google TV to Titan OS is a concrete illustration of the pattern: a significant European TV brand chose platform independence over continuing with Google's ecosystem. That is one defection, but it points to a broader calculation other OEMs are making.
VIDAA's rise deserves particular attention. Omdia's Maria Rua Aguete described the European TV OS landscape as undergoing a "structural shift," with Chinese manufacturers like Hisense and TCL "not only gaining share in hardware, but now scaling their own platforms, challenging the long-standing dominance of Korean players," according to Omdia's April analysis. VIDAA's growth has been driven by competitive pricing, broader European distribution, and expanded marketing campaigns, the same dynamics that originally made Hisense an attractive Google TV partner, now directed toward a competing platform. David Tett, Principal Analyst at Omdia, put the underlying momentum plainly: Chinese vendors are rapidly expanding their installed base through strong shipment growth across Europe, and that growth is now flowing to platforms they own.
The North American picture is even more telling. Google TV has been reported around 10%–13% in North America, though more recent reporting puts it below 10%. This is not a market where Google TV ever established dominance. Tizen, Fire TV, and Roku have long defined the North American shelf. What has changed is that a new entrant is about to reorganize the competitive order entirely.
Walmart's acquisition of Vizio and the subsequent transition of its Onn. TV brand from Roku to CastOS is projected to push CastOS from 6.5 million North American shipments in 2025 to 15 million by 2029, leapfrogging Roku, Tizen, and Fire TV to become the region's leading TV OS by volume, per Omdia's projections. Google TV does not figure in that reshuffling as a winner. It figures as a bystander.
Those regional losses look fragmented on the surface. The economics behind them are not.
Why the economics have shifted: platforms as commerce infrastructure
The answer to why OEMs and retailers keep choosing against Google TV, despite its Play Store access, content partnerships, and enormous installed base, is that the value proposition of owning a TV platform has fundamentally changed. It is no longer primarily about providing a capable interface or a broad app catalog. It is about controlling an advertising and commerce surface at scale, and ownership captures far more of that upside than licensing does.
The logic of CastOS makes this explicit. Omdia analyst Matthew Rubin put it directly: Walmart's platform consolidation gives the retailer "a major asset that it can use not only to generate advertising revenue and sales growth, but also to compete more effectively with Amazon."
The platform is a commerce infrastructure. It gives Walmart a substantial installed base of TVs powered by a platform it owns, allowing direct advertising to customers and a retail media business built to rival Amazon's. Roku was collecting the value of Walmart's TV footprint before this transition. Now Walmart collects it directly.
The same logic, applied to hardware manufacturers, explains the VIDAA story. When Hisense licenses Google TV, it delivers the software layer, and the advertising inventory and user data that come with it, to Google. When it scales VIDAA, it captures that layer for itself. Competitive pricing and distribution strength made Hisense a natural Google TV partner in the first place. Those same forces are now driving VIDAA's expansion across Europe. The hardware economics have not changed; the software economics have.
India's antitrust settlement adds another dimension. According to K&S Partners' review of the case, India's Competition Commission found that Google's OEM agreements, specifically mandatory preinstallation of the full Google TV services suite, ACC/TADA constraints on shipping incompatible Android smart TV devices, and the tying of YouTube to Play Store access, imposed restrictive requirements on manufacturers.
Google agreed to offer an independently licensed Play Store and to release OEMs from fork-related constraints. The settlement did not collapse the platform. But it did loosen the contractual mechanisms Google used to keep OEMs inside the ecosystem, particularly in a market where Chinese TV brands with VIDAA ambitions are actively competing for shelf space.
Google TV's main TV-related announcement at I/O this week was improved pointer remote support. That is not inherently a problem. But it is a notable contrast with earlier cycles when the platform was actively expanding its pitch to OEMs and content partners, adding features and integrations designed to make licensing Google TV more attractive than building independently. The current posture looks more defensive.
Beyond CastOS, the fastest-growing TV platforms globally are VIDAA, projected to rise from 6% of worldwide shipments in 2025 to nearly 8% in 2029, and Fire TV, climbing from 4% to just over 5% over the same period, per Omdia. Neither licenses Google anything. They are growing precisely because their owners decided the software layer was worth controlling directly. Google TV is now competing against a value proposition that did not meaningfully exist five years ago: the TV OS as a direct commercial asset for whoever ships the hardware.
A platform at an inflection point
Android-based TV platforms will likely remain the world's largest TV OS category through the rest of this decade, though Omdia notes that this includes forked Android versions in China and is not the same as Google TV's consolidated reach. Omdia projects Android maintaining roughly 39% of global shipments through 2029, down slightly from 42% in 2025, but still well ahead of Tizen at 16% and every other platform.
Excluding China, where much of Android's share belongs to non-Google versions of the OS, that figure drops to 32%, a more accurate picture of Google TV's actual footprint. On the global market excluding North America and China, Google TV currently leads with roughly 40% share and is projected to retain over 35% through 2029, supported significantly by its position with TCL.
For app developers, streaming services, and advertisers, that installed base remains the largest single platform audience available. A platform can matter for distribution even as its use over hardware partners weakens.
The 300 million milestone is not a warning sign. It is a transition marker.
Google TV is moving from the growth phase, when OEMs were abandoning proprietary platforms to adopt it, into the defense phase, when OEMs and retailers are building proprietary platforms to move away from it. Those are opposite currents. The installed base provides stability; the shipment-share trajectory describes the challenge. They do not cancel each other out.
The more concrete implication is for the OEM negotiation itself. Google's ability to compel hardware partners to stay inside its ecosystem has diminished, both through regulatory pressure and through the changing economics of platform ownership.
What Google needs now is not a better interface or more streaming integrations. It needs to offer OEMs a commercial reason to license that is more compelling than what they can build for themselves, whether that is a share of advertising economics, deeper retail integrations, or something that makes the arrangement genuinely more valuable than ownership.
Based on current evidence, that pitch is getting harder to make. The numbers from this week's milestone are starting to say so clearly enough that a headline about 300 million devices cannot obscure it.
