You may already saw it on the Blu-ray movie covers. If not on the top of the cover you can find “Ultraviolet” or “UV”. It means that the movie is also available for other devices like tablets, smartphones, computer and game consoles.
If you buy the Blu-ray you will have the movie not only on the disc. You get also a code to redeem at www.uvvu.com (before you have to register a free account) and then you can stream it on your smartphone or tablet or download to your computer / Mac. You can register 12 internet capable devices and you can share your Ultraviolet movies with up to six family members. All the major studios except Disney support the service.
