Oyster, a subscription service for e-books that launched two years ago, is calling it quits.

Oyster may have been one of the first companies to launch an eBook subscription service, but the company wasn’t the only player in the space. The team announced on its blog that they’re “taking steps to sunset the existing Oyster service over the next several months”. We believe more than ever that the phone will be the primary reading device globally over the next decade-enabling access to knowledge and stories for billions of people worldwide.

No specific reason for the move is given, but the blog post alludes to “taking on new opportunities to fully realize our vision for eBooks”.

Whether this means Oyster will be gone, its reading technology may not be.

With the “sunsetting” of Oyster, on top of the recent closure of Entitle Books, ebook-lovers are left with little choice now for subscription services outside of Amazon and Scribd. Even Amazon has declined to discuss how well its service is performing. A rep for the search giant confirmed that “a portion” of the Oyster team has joined Google Play Books, its online store for books.

The startup has signed on all of the “Big Five” publishers as well as a bunch of smaller houses, bringing hundreds of thousands of new books to the selection of 1 million titles it now had available only for subscription download. “We want to build the company that takes ebooks into the next wave”. But even these publishers have chosen to wait as long as six months to release their newest titles on subscription services like Oyster.
