New ATSC 3.0 digital TV broadcasting standard (aka NEXTGEN TV), which has been made available in more and more US cities, continues its steady growth path, with stations in more than 50 markets and reaching 55 percent of households upgraded from ATSC 1.0.

ATSC 3.0 tuners can be found in select kits sold in the US from 2020, and some of them the best 4K TVs from LG, Samsung, Sony and Hisense that provide this feature. The benefits of ATSC 3.0 over the older HD digital TV standard include 4K high dynamic range video, immersive Dolby Atmos and DTS: X audio, and Dolby dialogue enhancement and volume leveling features. In addition, as it is based on the IP protocol, bi-directional data streaming is supported to provide an interactive component to TV shows and sports.
