Barnes & Noble just posted lackluster results for its fiscal fourth quarter, including a $57.7 million loss, and an 0.4 percent increase in revenue to $1.38 billion. Nook sales in particular took a hit in B&N's fiscal Q4, with revenue in the Nook business falling by 11 percent — though the company says that Nook content sales rose by 65 percent. Barnes & Noble says that device sales fell in the forth quarter due to higher returns, "lower selling volume, and lower average selling prices," and that it reclaimed Nook Simple Touch inventory following poor sales. It's not a fantastic follow up to the company's mixed Q3 results, and with rumors of a Microsoft / Barnes & Noble tablet thoroughly squashed, the company's road back up the hill looks a little steeper.
