A study from Northeastern University researchers found that most smart TV operating systems continue to transmit automatic content recognition (ACR) data even after users opt out of tracking. The findings highlight significant inconsistencies in privacy compliance across major platforms, including Samsung, Vizio, and Roku, which impacts data collection practices for targeted advertising.
The failure of major hardware manufacturers to respect privacy toggles creates significant regulatory risk as data collection practices face increased scrutiny. For the streaming ecosystem, this inconsistency undermines the reliability of ACR data used for cross-platform measurement and targeted advertising, potentially devaluing datasets from non-compliant OEMs. As advertisers demand higher transparency, platforms that fail to enforce technical opt-outs may face litigation or exclusion from premium ad buys. Watch for whether the FTC or international regulators launch formal inquiries into Samsung and Vizio following these specific technical findings.
A Northeastern University study found that Samsung and Vizio smart TVs continue transmitting ACR-consistent traffic even after users disable tracking.

No. Researchers found that webOS, Google TV on Sony, VIDAA OS, and Fire TV OS consistently respected user privacy toggles during testing.
The study identified that Samsung and Vizio platforms continued to transmit ACR-consistent traffic to data endpoints even after users opted out of the feature.
Antenna broadcasts were tracked across nearly every system analyzed, while Netflix and YouTube remained untracked. Additionally, five systems monitored HDMI port activity, though Roku OS and SmartCast OS did not.
