Walt Disney Co has launched Disney Movies Anywhere, a service for consumers to buy and watch Disney, Pixar and Marvel films online and store them in the cloud, in the latest bid by a Hollywood studio to encourage digital movie purchases. Disney, like other Hollywood studios, is trying to boost digital sales after consumers moved away in recent years from buying DVDs, cutting a lucrative source of revenue. The media company said in a statement it launched the new service on Tuesday, coinciding with the digital release of Disneys blockbuster animated movie Frozen. The service allows consumers to buy digital movies from a library of more than 400 titles through Apple Incs iTunes store and the Disney Movies Anywhere website and app. The purchased movies can be watched on a laptop or desktop computer, or on Apples iPhone, iPad and iPod Touch, Disney said.
