Oyster, a subscription service for e-books that launched two years ago, is calling it quits.
The service's founders announced in a company blog post Monday that they will move toward retiring the existing service in the next few months. The blog post did not give a reason for the closure but hinted that there were other ambitions for the service.
"We believe more than ever that the phone will be the primary reading device globally over the next decade," they wrote. "Looking forward, we feel this is best seized by taking on new opportunities to fully realize our vision for ebooks."
