The Google-owned web video site today released its new smart TV app with a simpler, more streamlined interface to help viewers more quickly find the videos they love to watch on the Tube.

“We are investing to deliver a lean back experience through recommendations,” the company told Fortune via email. “This will be available today in the YouTube app in smart TVs, game consoles, and streaming boxes in the US, but we plan to roll out to more countries in the future.”

The company points out more than half of the 18-to-49-year-old users it recently surveyed in the U.S. said they have watched YouTube videos on their televisions. And since 2015, Tube viewers have doubled the amount of time they spend watching videos on the app.

Some of the most popular video categories include late night TV shows, comedy, and animated shows, as well as movies and gaming-related content, according to the company.

Some of the site’s most popular web stars are reportedly being tapped to promote, “Daydream,” Google’s new mobile phone virtual reality software, which is due to launch within weeks.

Bloomberg reported earlier this week that YouTube celebs Justine Ezarik, a.k.a. “iJustine,” and the Dolan twins, Ethan and Grayson Dolan, will be featured in Daydream promotional videos that will stream on Hulu later this year.
