Google TV is also getting a significant and essential upgrade. The app is getting user profiles next month. This is essential for personalized recommendations, which was tough before, given there weren't personal profiles on the platform. Profiles on Google TV will apply to all Google accounts on the device, with each profile showing its watchlist, recommendations, and Google Assistant queries. Downloaded apps and app logins will also sync across all profiles. This feature will come to Google's Chromecast and televisions from Sony and TCL.
