The most popular smart TVs sold today use automatic content recognition (ACR), a kind of ad surveillance technology that collects data on everything you view and sends it to a proprietary database to identify what you're watching and serve you highly targeted ads. The software is largely hidden from view, and it's complicated to opt out. Many consumers aren't aware of ACR, let alone that it's active on their shiny new TVs. If that's you, and you'd like to turn it off, we're going to show you how. ACR screenshots everything you watch twice per second, sending the data back to the TV maker for content recommendations and targeted advertising. It doesn't matter where the video comes from, be it a cable box, streaming service, or game console. If the thought of having your viewing habits'however commonplace!'tracked at that level of detail makes you as queasy as it does me, The Markup's article has instructions on turning ACR off on smart TV platforms from Roku, Samsung, and LG, a non-trivial process that takes between 10 and 37 clicks, depending on the platform. I'm happy that I have no desire to replace our 12-year-old Panasonic TV.
