In addition to our current line-up of big brands, Amazon Instant Video has been one of the most commonly requested services from our customers,” said Eric Anderson, Vice President of Content and Product Solutions, Samsung Electronics America. “We are very proud to say that today we deliver on that request – along with a brand new UI available for the first time on Samsung TVs.”

The app is available today from the Samsung Apps store. Previously purchased or rented videos should appear automatically in the software’s video library. The company says the app should work on and 2012 Smart Samsung TV, but it appears earlier models will not be eligible for the service.
