Amazon's Video on Demand is a cross-platform, video delivery service. Users can download videos from Amazon and watch them on a number of devices. Also, certain televisions and set-top boxes allow users to browse, purchase, and watch the videos without ever visiting Amazon.com.
Amazon's Video on Demand has both movies and television shows that can be purchased outright, or rented. Rentals only last 24 hours, but are usually less than a third the cost of purchasing the content.
