William Lynch. Daily Republic Barnes & Noble CEO William Lynch has resigned. His resignation is effective immediately.

Michael Huseby will now be the CEO of NOOK Media and president of Barnes & Noble. Allen Lindstrom has been promoted and will serve as the company's new CFO.

The news isn't a huge surprise.

Barnes & Noble has largely failed to adapt to the growing tablet and e-reader market. And although its Android-based Nook tablets have received decent reviews, they haven't been selling very well.

In May, Barnes & Noble made a quiet admission that its Nook tablets weren't selling as well as it had hoped when it added Google's Play store for apps and other content. That means users are no longer incetivized to purchase digital content like books and movies from Barnes & Noble. It also means Nook owners were likely frustrated by Barnes & Noble's dim app selection for the tablet.

Here's the press release from Barnes & Noble announcing Lynch's resignation:

The Board of Directors of Barnes & Noble, Inc. (BKS) today announced that William Lynch has resigned as Chief Executive Officer and director of the Company effective immediately.
