Amazon Prime customers can now download their TV and movies on their iOS and Android devices, allowing them to watch the content offline, when they don't have access to the internet. Previously, offline access was limited to video content that customers had already purchased. With the new expansion the entire Prime library has been made available for offline viewing.
Amazon Prime Customers can download the latest version of Amazon Video directly on your devices through its respective app stores or by using the following links:
At the moment, offline access is not available for every movie and TV show due to licensing limitations. Some of the titles that are currently available for download include Amazon’s own shows, as well as titles from other publishers such as The Good Wife, Sons of Anarchy, and The Hunger Games. One particularly interesting addition to the list are the HBO shows that Amazon recently included in its library, such as Girls, Entourage, and The Wire.
Although offline access is a welcomed feature, the implementation needs improvement. For example, there's no way to figure out which movie or TV show has already been downloaded and is available for offline access. The user will just have to remember the download. Its important to note that Prime subscribers will have about 15 to 30 days to watch a movie or a TV show once it has been downloaded.
If you dont have Amazon Prime access, you can sign up for a $99 yearly subscription. Keep in mind that Amazon Prime also offers several other advantages.
