It's the end of an era, my friends. If you fire up YouTube on your Wii, you'll be greeted with the following message.
"This device will no longer be compatible with the YouTube platform starting June 30th. For a list of compatible devices, go to (YouTube help website)."
If you're still using your Wii to view YouTube content, it looks like you'll need to find another device quite soon. Thanks to FangztheWolf for the heads up!
