GoKawiilNortheastern study finds Vizio, Samsung TVs keep tracking after users opt out
A Northeastern University study ran 5,943 experiments across twelve smart TV platforms and found that automatic content recognition (ACR) tracking often continues even after viewers disable it. Vizio's SmartCast devices sent data to an Amazon Kinesis endpoint in 100% of opted-out test scenarios, while Samsung Tizen devices showed ACR-like traffic in over 60% of cases; only four operating systems fully honored opt-out requests.
