Does Opting Out of TV Tracking Actually Work? Northeastern Study Tests 12 Smart TVs

Smart TVs from major brands like Samsung, LG, and Vizio are known to collect viewing data, but a new study from Northeastern University asks whether the opt-out mechanisms for automatic content recognition (ACR) actually stop the tracking. Researchers monitored 12 TVs from 10 manufacturers to see what happens when users disable ACR in settings. The findings reveal that opting out does not always prevent data collection; some TVs continued to send viewing information to company servers or third parties even after users turned off the feature. This matters because ACR data can be used for targeted advertising and can reveal sensitive details about a household's interests and habits. The study highlights the complexity of TV privacy controls and the need for clearer, more effective opt-out options. As smart TVs become the center of home entertainment, consumers should be aware that simply toggling a setting may not fully protect their privacy.
