Wii U's Nintendo TVii service will launch tomorrow, December 20 in the US and Canada.
According to the platform holder, the delayed Wii U service will let users find, watch and engage with TV content "in entirely new ways".
Nintendo TVii will enable Wii U owners to use the GamePad to browse and search for programming from sources they're subscribed to, and engage with others about content through Miiverse, Facebook and Twitter.
At launch, the service will support cable and satellite providers in both regions, plus direct integration with Amazon Instant Video and Hulu Plus subscriptions in the US.
Further integration with Netflix subscriptions and TiVo are expected in early 2013 in the US.
"After Dec. 20, you'll never look at your TV the same way again," said Nintendo of America president Reggie Fils-Aime.
"Wii U owners have already experienced the transformative effect that the GamePad has on game play and social interaction. Nintendo TVii shows how the integrated second screen of the GamePad can also transform and enhance the TV viewing experience. Welcome to the new world of TVii."
Nintendo TVii will launch in select European regions in 2013.
