Vizio is partnering with Pluto TV to add a free video streaming service, called WatchFree, to “nearly all” of the company’s SmartCast televisions. WatchFree will get its own dedicated input, so it’ll have nearly the same prominence as your HDMI inputs and the main SmartCast screen. WatchFree is rolling out starting today.

When you switch over to it, you can browse between “more than 100 live and linear channels” covering TV shows, movies, news, sports, concerts, and “viral videos,” according to Vizio. (Did you see that one of the dog running around with the GoPro? Real good.)
