New submitter mikeebbbd writes: "U.S. regulators on Thursday approved the use of new technology that will improve picture quality on mobile phones, tablets and television, but also raises significant privacy concerns by giving advertisers dramatically more data about viewing habits," reports Reuters. ATSC3.0 will apparently make personal data collection and targeted ads possible. New TVs will be necessary, and broadcasters will need to transmit both ATSC 2.0 (the current standard) for 3 to 5 years before turning off the older system. For now, the conversion is voluntary. There appears to be no requirement (as there was when ATSC 2.0 came out) for low-cost adapter boxes to make older TVs work; once a channel goes ATSC 3.0-only, your old TV will not display it any more.
