A study by Northeastern University researchers found that Samsung and Vizio smart TVs continue to transmit automatic content recognition (ACR) data even after users have opted out of tracking. The findings suggest that privacy settings on major smart TV operating systems may not effectively prevent data collection, raising concerns about the transparency of ACR implementations.
The failure of privacy toggles on dominant platforms like Tizen suggests a significant gap between consumer expectations and actual data practices. As ACR data remains a cornerstone for targeted advertising and cross-device attribution, these findings could invite increased regulatory scrutiny regarding how OEMs handle viewing fingerprints. The discrepancy between hardware manufacturers—where Sony and LG respected opt-outs while Samsung and Vizio did not—creates a fragmented privacy landscape for advertisers relying on this data. Watch for potential updates to Tizen and Vizio software versions as researchers continue to monitor encrypted traffic destinations.
This smart TV tracking opt-out failure highlights the ongoing tension between hardware-level data collection and user privacy controls in the connected TV ecosystem.

No, a Northeastern University study found that Samsung smart TVs continue to transmit data even after users disable automatic content recognition settings.
Research indicates that LG's webOS, Amazon Fire TV, and Google TV on Sony devices successfully respected privacy selections during testing.
Roku OS successfully blocked third-party tracking, though it continued to collect data for its own proprietary streaming service.
Samsung's Tizen OS currently leads the U.S. market with a 34% share of smart TVs.
