Back in September Yahoo launched a new Yahoo Screen iOS app, a TV remote-like experience for browsing content from Yahoo and sending content to your TV via AirPlay. Today the company announced that it is launching the Yahoo Screen experience directly on the Apple TV.

Yahoo Screen on Apple TV helps you quickly find all the great video Yahoo has to offer —Saturday Night Live, The Colbert Report, The Daily Show with Jon Stewart, live news and events, music and original Yahoo programs — so you can enjoy on your big screen.

The app appears to be a similar experience as the iOS app, allowing users to browse through content hosted on Yahoo across categories such as news, sports, food and entertainment and instantly stream content to their TV. Yahoo! has made new deals with Viacom that will bring content from Comedy Central and elsewhere, and it will also live stream original Yahoo programs, news, and live events. A few of the shows already available on Yahoo Screen include Saturday Night Live, The Colbert Report, and The Daily Show with Jon Stewart. You’ll also find content from MLB, UFC, The Onion, ABC News, Martha Stewart, and more.

The apps are being pushed out over the air to the Apple TV in the U.S. now, and we’ve also discovered that a new PBS channel has arrived today (pictured above). The app doesn’t require users to have a TV subscription to access content, but it does require users to sign in using Google+, Facebook, or the app’s registration in order to access PBS broadcasts for their location. The app doesn’t have live content, but it does have many of the network’s new shows shortly after they’ve aired.

Apple has been quietly beefing up Apple TV with a ton of new content in recent months. Earlier this year Apple added Time Warner’s HBO GO, as well as WatchESPN, Sky News and more to its existing Apple TV service, and later added channels for Vevo, Disney, Weather Channel, Smithsonian, and Major League Soccer.

Apple has long been rumored to launch a revamped Apple TV service that many hope will include an SDK for bringing iOS apps to the bigger screen, and some analysts still expect the company to launch a full fledged TV set late this year or early next. Apple hasn’t said much about its TV plans, but it’s also added some big new features to Apple TV this fall including Mavericks display integration, iTunes Radio, and the new iMovie Theater app.
