Smart TVs Spy on What You Watch and Profit From Your Data
Last week we read a news story about how some Smart TVs install apps that use your IP address and bandwidth to scrape the Internet to feed AI models. And if that isn’t enough to make you want to disconnect your TV from the Internet, smart TVs from nearly every major brand are actively spying on exactly what you watch—whether it's cable, streaming apps like Netflix, over-the-air broadcasts, Blu-ray discs, or even content from a laptop, game console, or phone connected via HDMI. They do this through a built-in technology called Automatic Content Recognition (ACR) that takes frequent screenshots and audio fingerprints of what you are watching. Then, using the data, the content is identified, and detailed viewing information is sent back to the manufacturer’s servers.
This isn’t occasional tracking; studies show Samsung TVs send data roughly every minute and LG every 15 seconds, even when you’re using the TV purely as a monitor for personal photos, videos, or work. The result is a highly detailed profile of your watching habits that gets turned into cash.
How ACR Spying Works
ACR software runs in the background on most smart TVs. Manufacturers then build individual or household viewer profiles. In addition to Samsung and LG, Sony, Vizio, TCL, Hisense, Roku TVs, and others also use ACR software to build user profiles.
How They Make Revenue From Your Viewing Data
TV makers often sell hardware at razor-thin (or even negative) margins because the real money comes later from your data:
- Selling or licensing data to advertisers, data brokers, and measurement companies. Advertisers get precise audience insights for targeting ads on TV, phones, and other devices.
- Running their own ad platforms on the TV home screen and apps—personalized ads based on what you’ve watched.
- Cross-device retargeting: Your TV habits influence ads you see on YouTube, social media, or elsewhere.
- “Post-purchase monetization”: Companies openly say they make more ongoing revenue from data and ads than from the initial TV sale. Some users even get “free” or ad-light apps in exchange for allowing extra tracking.
Your viewing habits are packaged and sold as valuable advertising intelligence—often without you realizing the full extent.
Watchdog Groups Fight Back
- 2017 Vizio Case: Vizio secretly tracked 11 million TVs and sold the data without consent. The FTC fined them $2.2 million; the company admitted to collecting second-by-second viewing habits and linking it with demographics for advertisers who could then target you across phones and computers.
- 2024–2025 Research: University studies confirmed TVs send massive amounts of viewing data regardless of source, creating “digital fingerprints” of users.
- December 2025 Texas Lawsuits: Attorney General Ken Paxton sued Samsung, LG, Sony, Hisense, and TCL for using ACR to collect and monetize viewing data without clear informed consent. Temporary restraining orders were issued against some companies, and Samsung later agreed to get explicit consent in Texas.
The Proxy Network Angle
We briefly spoke about this on the last show. A separate but growing practice involves certain smart-TV apps quietly enrolling your device in massive residential proxy networks like Bright Data. In exchange for fewer ads or free access, the app turns your TV into a web-scraping bot that uses your IP address and bandwidth to crawl public websites, collect data (including audio/video), and feed AI training models. Major platforms like Amazon, Google, and Roku have started blocking some of these, but they still run on LG webOS and Samsung Tizen in many cases.
Bottom Line
Your smart TV is effectively a 24/7 surveillance device in your living room that turns your private viewing into a profitable data product. While some data collection is now supposed to require opt-in consent, most people never notice the setting. The industry’s business model increasingly depends on this surveillance, which is why cheap TVs keep getting smarter—and more invasive.
