Could Penguin Beat Amazon at Book Subscriptions? - Businessweek

Where "unlimited" is supplier-defined; check the full article for speculation about how Amazon could be disintermediated by the subscription service shift

"Subscription services for digital media, such as movies and music, have become mainstream, making it more or less inevitable that book publishers would have to grapple with a similar model. Such startups as Oyster and Scribd offer these services already, but there has been a sense that the book market hadn’t yet heard from the big guns. Well, Amazon.com (AMZN) is about to take its shot.

The company is testing an e-book subscription service called Kindle Unlimited, according to pages on its site that were noticed by its users and the tech blog GigaOM. The service would cost $9.99 a month and give people unlimited access to about 600,000 titles as well as thousands of audiobooks. Amazon hasn’t responded to a request for comment."
