Well, there was previously the YouTube app for Xbox 360, Playstation 3 and Vita and now this, Wii. You can make use of the Wii Remote to browse the app and search on which video you may want to watch. However, this kind of interaction is not as good as using the Playstation Vita or Xbox Smartglass to search for whatever YouTube video you want to look for. For Xbox SmartGlass, you can use the mobile device to type in the stuff you want to search on the app.
