I listened to this radio segment the other day and was interested in learning how the NextGen TV roll-out is going because I've long tuned into television using an antenna for over-the-air reception and recently purchased a new
@sonyxperia with a built-in ATSC 3.0 tuner (to get 4K Ultra HD and high dynamic range from the upgraded new broadcast signals).
NPR reports that:
NextGen is the biggest change to broadcast TV since 2009, when stations shut down the analog signals that they'd been transmitting since the 1940s and transitioned fully to digital. The rollout of NextGen, also known as ATSC 3.0, began three years ago. Today, it's available to around three-quarters of Americans, mostly in major cities.

ATSC is an acronym for Advanced Television Systems Committee, which is an international, non-profit organization that develops voluntary standards for digital television. ATSC 3.0 is the next generation terrestrial broadcast system designed from the ground up to improve the television viewing experience with higher audio and video quality, improved compression efficiency, robust transmission for reception on both fixed and mobile devices, and more accessibility, personalization and interactivity.

Wikipedia says that ATSC 3.0 is:
...designed to offer support for newer technologies, including HEVC for video channels of up to 2160p 4K resolution at 120 frames per second, wide color gamut, high dynamic range, Dolby AC-4 and MPEG-H 3D Audio, datacasting capabilities, and more robust mobile-television support. The capabilities have also been foreseen as a way to enable finer public alerting and targeted advertising.
