Thinking of buying a new TV this “Black Friday” or holiday season? There’s some new TV technology that could sway your decision on what model to buy.

NextGen TV, which delivers 4K broadcasts, surround sound and web-like content, has begun rolling out across the U.S. Currently, more than a dozen cities in the U.S. have TV stations broadcasting these new improved TV signals.

More than 20 markets are expected to be on the air by the end of the year and there are 20 different TVs with the tuners needed to handle the signal already in stores.

So far, most of the broadcasts are high-definition TV broadcasts with improved audio. Cities where NextGen TV signals are being broadcast will begin to see a new on-air commercial with the approach of the holiday shopping season, a common time for new TV purchases.
