The next version of broadcast TV, called NextGen TV or ATSC 3.0, continues to roll out across the US, and will reach an estimated 75% of households by mid-2022. Upgrades over current antenna TV potentially include 4K resolution, enhanced sound quality and the web-like ability to interact with broadcasters via your television set. Unlike cable or streaming services, you can watch these broadcast channels for free, over the air with a standard antenna. You can find a list of available ATSC 3.0 areas here, and the number is growing by roughly two markets every month.
