Much like the arrival of Hulu Plus on Wii U, good things come to those who wait. Joining yesterday's addition to the TV streaming options on Nintendo's new system, and Netflix which was ready on day one, is Amazon Instant Video, live right now.
If you're a subscriber to the service, simply tap on the tile visible on the home menu and a download will start from the eShop. Once the app is installed you'll need to login, register the device following on-screen instructions, and then you should be good to go. It has the features that you'd expect, with lots of content and the ability to use the GamePad screen for navigation or watching away from the TV.
One neat inclusion is integration with Amazon's Whispersync, which means that you can stop watching a show on your Wii U, switch to another device — such as a PC, smartphone or tablet — and pick up from the exact spot where you left off; it shows that the app is fully connected and using the online service to its potential.
So there you go, you now have three TV subscription-based streaming services to choose from on Wii U in North America. You'll also have the chance to try Nintendo's own app, TVii, when it arrives in December.
