Amazon.com Inc. is planning to start a service that would let people store music and video online and access it from various digital devices, people familiar with the matter said.
The company could announce the effort as early as Tuesday, the people said.
Amazon is still working out key legal issues related to the service, these people added. Most notably, Amazon has yet to secure content licenses from at least some major record labels and movie studios.
One major music company, Sony Corp.'s Sony Music Entertainment, expressed dismay at Amazon's plans, echoing concerns of others in the industry. "We are disappointed that the locker service that Amazon is proposing is unlicensed by Sony Music," a spokeswoman said Tuesday evening.
An Amazon spokesman didn't respond to requests for comment.
Amazon executives have told several media companies that they are likely to seek licenses after this week's expected announcement.
The online retailer appears to be racing Apple Inc. and Google Inc., both of which are also working on similar offerings, known as "locker" or "cloud" services.
Such services create an online music or video collection identical to the one on a user's computer hard drive, then let the user access the collection from elsewhere.
