Today Apple added four new channels to Apple TV including UFC.TV, The Scene (a digital video shorts channel), Fusion (a news and pop culture channel), and Dailymotion (a video sharing site). All four of those channels were made available immediately, with App Apple drawing attention to them with flags of “New” on the main screen icons. Some countries may have restrictions.
As a side-note, the UFC channel is by subscription or pay-per-view only.
YouTube has updated its app on Apple TV as of today as well, with a better experience and improved look. The full video catalog is now available with the app. Users will also experience better search with predictive results, more subscribe capabilities, and improved recommendations for those signed in. The way Apple treats third-party software is different compared to in the App Store for iPad and iPhone, but lately Apple has increased the frequency when it comes to when new content partners are added. Now that YouTube has been updated, it will help Apple TV stay fresh.
