Nook segment sales at Barnes & Noble fell 12.6% over the nine-week holiday season compared to the same period last year.

At the same time, the company saw sales rise 13.1 percent in digital books, digital newsstand, and the apps business revenues.

CEO William Lynch had this statement: “We entered the holiday with two great new products, NOOK HD and NOOK HD+, both  highly rated media tablets of phenomenal quality … NOOK device sales got off to a good start over the Black Friday period, but then fell short of expectations for the balance of holiday.   We are examining the root cause of the December shortfall in sales, and will adjust our strategies accordingly going forward.”
