Your smart TV is capturing a screenshot of your screen roughly twice per second. Not occasionally, not when you open certain apps — continuously, while anything is playing, whether that content came from Netflix, a broadcast antenna, a gaming console, or a USB drive.
This is Automatic Content Recognition, or ACR, and it’s been running on Samsung, LG, Sony, Vizio, and Roku televisions for years. In May 2026, Samsung sent direct emails to customers confirming that ACR runs on their sets, collects viewing history, and shares it with advertising partners. The emails followed a legal settlement with the Texas Attorney General — the first ACR enforcement action by a state regulator in the U.S.
Most people with a smart TV have ACR running right now. Most never agreed to it in any meaningful sense.
What ACR Does, Technically
The mechanism is simpler than its name suggests.
Every 500 milliseconds — twice per second — the TV’s software captures a sample of whatever is on screen. That sample is converted to a compact fingerprint, a numerical representation of the visual content. That fingerprint is sent to a recognition server operated by the TV manufacturer or a third-party ACR provider.
The server matches the fingerprint against a database of millions of shows, films, commercials, sporting events, and live broadcasts. When it finds a match, it logs what you were watching, when you were watching it, and for how long. That record is associated with your Personalized Service ID — a persistent identifier linked to your device and, in many cases, your account — along with your IP address.
The result is a granular, timestamped record of your television viewing history. Not what you selected from a streaming menu, but literally what appeared on your screen, including content from cable boxes, Blu-ray players, gaming consoles, and any other HDMI-connected device.
Why TV Makers Built This In
ACR exists because viewing data is valuable advertising infrastructure. The business rationale is straightforward.
Traditional TV ratings relied on statistical samples — Nielsen panels that extrapolated viewing behavior from a small slice of households. ACR replaces estimation with measurement. A TV maker that knows, device by device and minute by minute, exactly what millions of televisions are displaying has a data asset that advertisers will pay for, and a competitive advantage in the streaming landscape where attention data drives ad pricing.
The data is also used to serve “Sponsored Content” recommendations on smart TV home screens — suggestions that are paid placements, shaped by what the ACR record suggests you’re likely to engage with.
TV manufacturers have framed ACR as a feature that improves your experience: better content suggestions, more relevant ads, personalized recommendations. The technical description is accurate. Whether the user experience is improved depends on how you feel about your viewing history being catalogued in a database and monetized.
The Samsung Texas Settlement
In February 2026, Samsung became the first TV manufacturer to settle an ACR enforcement action, reaching an agreement with Texas Attorney General Ken Paxton over ACR data collection practices.
The substance of the settlement: Samsung agreed to stop collecting ACR data without explicit consent from Texas residents, and to rewrite its consent screens to be clear about what ACR is and what it collects. The existing practice — burying ACR opt-in inside setup flows designed to generate agreement without comprehension — was found to violate Texas privacy law.
In May 2026, Samsung followed the settlement with direct emails to Smart TV customers confirming that ACR runs on their devices, describing what’s collected (viewing history, Personalized Service ID, IP address), and explaining how to disable it.
The emails are notable because they represent the first time a major TV maker has affirmatively disclosed ACR’s existence to its existing user base rather than relying on setup-flow consent. They’re also evidence that the regulatory environment around ACR has shifted — manufacturers can no longer rely on buried disclosure as a complete legal defense.
The settlement covered Texas residents and imposed no financial penalty, but established a precedent that ACR opt-in consent must be meaningful, not incidental. Other state attorneys general have indicated interest in similar actions.
What Your Viewing History Can Reveal
Viewing history feels less sensitive than medical records or financial data. It isn’t, necessarily.
What you watch over time reveals patterns that advertisers — and insurers, employers, and data brokers who buy the data downstream — can use to make inferences about you. Regular viewing of late-night content correlates with sleep patterns. Religious programming correlates with affiliation. Political news correlates with affiliation in a different direction. Health-related content correlates with medical conditions, pregnancy status, and mental health.
These inferences aren’t certain, but they don’t need to be. Data brokers who purchase ACR data combine it with other purchased records — location data, purchase history, credit records — to build profiles that are more accurate than any single source. Your television viewing is one of many inputs into a commercial data record about you that you didn’t author and can’t inspect.
Advertisers aren’t the only potential recipients of this data. In the U.S., law enforcement can subpoena data held by third-party companies without the same warrant requirements that apply to a direct search. If your viewing history is sitting on a third-party ACR provider’s servers, it’s accessible to that extended set of actors.
How to Disable ACR on Each Major Platform
Disabling ACR is possible on every major platform, though the path to the setting varies by manufacturer and changes with firmware updates. Here are the current locations as of mid-2026.
Samsung: Settings → Support → Terms & Policies → Viewing Information Services. Toggle off “Viewing Information Services.” Also check Settings → Privacy → Interest-Based Advertising.
LG: Settings → All Settings → General → AI Service → AI Recommendation → Interest-Based Advertising → Off. LG’s ACR system is called LivePlus; you may find it under Settings → All Settings → General → LivePlus.
Sony (Google TV): Settings → Privacy → Samba Interactive TV. Some Sony models call the setting “Interactive TV” under Settings → Device Preferences → Privacy → Samba Interactive TV.
Vizio: Menu → System → Reset & Admin → Smart Interactivity → Off. Vizio licenses ACR from Inscape (now owned by VIZIO/Walmart); this setting is labeled “Smart Interactivity” in their UI.
Roku: Settings → Privacy → Smart TV Experience → Use Info from TV Inputs → Off.
After changing these settings, verify by returning to the same menu. ACR can occasionally be re-enabled by firmware updates or factory resets — worth checking after any major software update.
ACR and External Devices
One aspect of ACR that surprises people: it captures what’s on the physical screen, not what’s being streamed through the TV’s own apps.
That means ACR can potentially log content from:
- Cable and satellite set-top boxes
- Gaming consoles (PlayStation, Xbox, Nintendo Switch)
- Blu-ray and DVD players
- Any HDMI-connected device
The TV doesn’t know where the content is coming from — it only sees pixels. If those pixels match something in the fingerprint database, the match is logged regardless of whether the content originated inside or outside the TV’s own software ecosystem.
For gaming specifically, this means ACR could log which games you’re playing, when, and for how long — data that has obvious value to advertisers, publishers, and platform operators who buy data from TV manufacturers.
The Broader Pattern
ACR is one piece of a larger pattern in consumer electronics: devices that are sold on hardware margins but monetized on data generated during use.
A television that cost less because the manufacturer planned to recoup revenue through advertising data is a device with a different relationship to the user than one purchased at full price with no data monetization. Neither model is inherently wrong — the economics of consumer electronics are complicated — but users benefit from understanding which model they bought.
The Samsung settlement, and the emails that followed it, represent a moment where the gap between what manufacturers disclosed and what users understood became legally significant. ACR didn’t change; what changed is the standard for informed consent.
Disabling ACR doesn’t remove all data collection from your smart TV — app usage data, search history within the TV’s own interface, and account-level behavior within streaming platforms operate through separate systems with separate controls. But it does stop the most invasive form of passive collection: the continuous fingerprinting of whatever appears on your screen, regardless of where it came from.
That’s worth five minutes in your TV’s settings.
