Moowee.tv allows you to view internet television on your TV via your Nintendo Wii. Their web page FAQ states that the “moowee.tv user interface is currently optimized for TV with Nintendo Wii remote control buttons mapped to the application”. Digging further into their web page I found that
not only can you view content, but you can also create your own custom station and share content with other users as well. The service also recommends stations you may like based on your current content views using none other than tag words. The company also maintains a blog which is full of tips and tricks for users, as well as detailed explanations regarding common hook-up issues.
