Google just announced on its Official Google TV Blog the “big announcement” for tomorrow. The Google TV crew announced an all-new YouTube app for the Google TV platform. The app features a smoother experience and bug fixes. The big feature here, however, seems to be a new feature called “Discover” that lets users view YouTube channels by different categories (as seen above).

The YouTube app will also gain the new channels that the desktop version of YouTube has seen. From there, you can navigate through users’ videos, favorites, and subscriptions.

When viewing a video, you can use the up and down arrows on your Google TV’s remote to navigate to the information screen. On the information screen, you can interact with a video by giving it a thumb’s up, adding it to your favorites or playlist, and leaving a comment.

The update should roll out to every Google TV user in the next few days from the Android Market. Oh, and I have to say that I am disappointed. Google overhyped this announcement.
