Barnes Noble has had a rough few quarters, with the company losing tens of millions or dollars on lagging sales of its Nook tablets and e-readers. But throughout all that pain, one man has consistently acted as Barnes Nobles most outspoken advocate: Michael P. Huseby, formerly the companys president and CEO of its Nook Media division. Today, the company announced Huseby has been promoted to CEO of the entire company, filling the vacancy left in the wake of the resignation of William Lynch last summer. The promotion is largely a ceremonial one, given that Huseby has been in charge of operations since Lynchs ouster six months ago.
