There may be a grand unifying service to make accumulating a large digital cinematic library feasible, or so is the hope anyway. From a report: For several years now, Disney has been the only Hollywood studio with a digital movie locker worth using, but a host of other industry heavyweights have now jumped on board to launch an expanded version of the service called Movies Anywhere. It's both a cloud-based digital locker and a one-stop-shop app: customers connect Movies Anywhere to their iTunes, Amazon Video, Google Play, or Vudu accounts, and all of the eligible movies they've purchased through those retailers appear as part of their Movies Anywhere library. Given that the Movies Anywhere app works across a number of platforms, it basically allows them to take their digital film library with them no matter what device or operating system they're using. [...] The launch of Movies Anywhere should be the merciful, final blow that puts an end to UltraViolet, one of the entertainment industry's first attempts at putting together a comprehensive digital locker service. That service flailed due to a poor customer experience and lack of adoption on the part of big digital retailers like Apple. The team behind Movies Anywhere seems to have learned from UltraViolet's mistakes, however, as well as Disney's previous successes.
