UltraViolet, the digital rights locker that gives you a way to view the movies and shows you purchase from various services, will shut down on July 31st. If you're not familiar with the service, it stores only licenses (and not the content itself) in the cloud to enable playback on multiple devices regardless of their origin. You can even use it to redeem codes for digital copies that come with physical purchases. UltraViolet has announced the news on its website, along with instructions not to close your libraries or to unlink them from supported retailers. It's working with those retailers to maximize your continued access to the movies and TV shows in your list.
