More than 20,000 videos available to Prime customers.
Amazon Instant Video lets Amazon Prime Instant Video members stream Prime content to their iPad for free as well as download video for offline viewing. The company say that more than 20,000 movies and TV shows are available for streaming on Prime.
Those without Prime can still use the app to access video they have previously purchased or rented from the Amazon Instant Video store. Users can also subscribe to a TV season pass, and the episodes will automatically be available on their iPad the day after they air.
Coming just one day after Hulu Plus was added to Apple TV, the app isn't available on iPhones yet but it's only a matter of time.
