Does your TV know what you’re watching? Yes. And it uses a complex pipeline to do it. It’s called ACR (automatic content recognition) and it takes screen grabs of what is on the screen to identify what content is being displayed. Once it builds a library of your viewing history, it can sell that data to brokers who then use it to build customer profiles for targeted advertising. The good news is it’s optional, your tv just comes with it turned on automatically.
