The following video is from Thursday's MarketFoolery podcast, in which host Chris Hill, along with analysts Jason Moser and Joe Magyer, discuss the top business and investing stories.

In this segment, sales of Barnes and Noble's (NYSE:BKS) e-reader device, the Nook, have taken a big turn downward. Joe notes, however, that sales of the actual e-content for the Nook are up. The guys discuss whether or not this silver lining is enough, and if falling Nook sales aren't just too big of a red flag for the company in the face of increasing competition from other tablets, like Apple's (NASDAQ:AAPL) iPad.
