Barnes & Noble hires former Motorola and Zinio execs to help run Nook

Barnes & Noble (s BKS) is hoping to build up the beleaguered Nook Media division with two new executive appointments. The company announced Monday afternoon that it’s hired Mahesh Veerina as chief operating officer of the Nook division and Doug Carlson as EVP of digital content and marketing.

Veerina and Carlson will report to Michael Huseby, the CEO of Nook Media. Since William Lynch’s departure in July, Barnes & Noble does not have one CEO overseeing the entire company; instead, the retail and digital divisions are being run separately.

Veerina founded mobile software company Azingo, which he sold to Motorola in 2010. He then worked as Motorola’s SVP of software and services until 2012.

Carlson was the executive chairman of digital magazine newsstand Zinio until 2012. Before that, he cofounded Fiji Water. He’s also worked for a number of hotel and spa companies and served as a board member for a group of Napa wineries.

The hires come at a time of upheaval for the company. Nook revenues fell 20 percent in the most recent quarter. The company had hoped to spin off the Nook division, but at least for now that’s no longer in the cards, and future Nook tablet strategy is unclear.

“With these new appointments, I’m confident that we’ve now structured our business in a way to best position us for success,” Huseby said in a statement.
