What they're attempting to do seems fundamentally impossible to me. Personalization requires there is a specific person tied to the output. With phones and PCs, that's a fairly reasonable assumption. With a television, it quite often isn't. Services allow you to create individual "who is watching" profiles, but the reality at least for my family is no one uses those. We all watch from the same account and same profile. We also watch together, in which case there is no answer to a question that assumes only one person can watch at a time. Sometimes, no one is watching and the stream is simply left on while everyone is sleeping or out of the house and autoplay is streaming to an empty room. Sometimes, we leave things on intentionally for the cats. My wife has ADHD and puts something on only to walk away two minutes later, but it's still on.<p>In some extremely dystopian future that I'm sure is coming quickly, a television may be equipped with video surveillance capability that can identify eyeballs in real time and decide exactly what animal is viewing what part of the screen and estimate from bloodflow in the face and pupil dilation the extent to which they care and are paying attention, but we're definitely not there yet.<p>Right now, this is still just snake oil they're selling to ad buyers. Why I get almost all fast food, beer, and insurance ads, even though I don't drink, haven't eaten fast food since 2002, and haven't changed insurance providers since 2008.
