The television in the average American living room has quietly become one of the most data-hungry devices in the household. Roughly 100 million US homes now own a smart TV, and almost all of them ship with a feature called Automatic Content Recognition, or ACR — software that takes a snapshot of whatever is on screen about twice a second, identifies it against a global content library, and sends that information back to the manufacturer. ACR runs whether you're watching cable, streaming Netflix, playing a video game, or casting from your phone. It's how TV makers know what shows you watch, what ads you skip, and even what plays on devices plugged into the HDMI port. Most people have never heard of it.

Who is doing the watching matters. About 60% of the world's smart TVs are built in China, and Chinese-owned brands — TCL, Hisense, Xiaomi, Skyworth, Konka, Changhong — sell roughly a third of all sets globally. Hisense and TCL alone account for about a quarter of the US market. Hisense's TV operating system, VIDAA, is the second most widely used in the world. When a Hisense or TCL set sends viewing data home, "home" is a server in China — and under Chinese law, the government can request that data at any time.

Perhaps the most striking part of the picture: there is no major American smart TV manufacturer. Samsung and LG are South Korean. Sony is Japanese. TCL, Hisense, and Xiaomi are Chinese. Vizio, the one remaining US brand, was bought by Walmart in 2024 and doesn't actually build its own televisions — it puts the Vizio name on sets manufactured in China. The country that invented the television no longer makes one.

That tension has finally surfaced in court. In December 2025, Texas Attorney General Ken Paxton sued the five biggest TV makers — Sony, Samsung, LG, Hisense, and TCL — for collecting and selling viewing data without permission. Days later, a Texas judge issued the first restraining order ever filed against a smart TV manufacturer, forcing Hisense to stop. A similar order against Samsung followed in early January but was vacated by the same judge a day later; Samsung subsequently reached an agreement with the Texas AG to halt ACR collection from Texans without explicit consent. The cases against Sony, LG, Hisense, and TCL remain active. Meanwhile, the FCC has begun using its Covered List authority to bar certain foreign-made connected devices from receiving equipment authorization — first foreign-produced drones in December 2025, then foreign-produced consumer routers in March 2026. Smart TVs are not on the list, but the regulatory template now exists and could be extended to other connected consumer devices if a national security agency makes the required determination.
