Live TV streaming service YouTube TV is now available on actual TVs with the launch of dedicated apps for smart TVs, streaming devices and gaming consoles. Following its rapid expansion across the U.S. since its April debut, Google’s popular competitor to Sling TV, PlayStation Vue, Hulu Live TV, and DirecTV Now, is available to two-thirds of the U.S., including the top 50 metro areas, the company also notes.

Until today, YouTube TV has been available via mobile, desktop and casting, but did not have a standalone app for TV viewers.
