In spite of this fall's launch of the Nook HD+, Barnes & Noble's (BKS) Nook division sales fell 12.6% Y/Y during the holiday season, the company reports. The decline in Nook hardware appears to be even worse, given digital content sales rose 13.1%. A freefalling e-reader market has to bear some responsibility for the decline, but with the tablet market much healthier, competition from the iPad Mini, the Kindle Paperwhite, and other hardware seems responsible as well. B&N's retail sales fell 10.9%, and saw an 8.2% drop in same-store sales (-3.1% exc. Nook).
