Barnes and Noble (NYSE:BKS) was the biggest loser on the New York Stock Exchange today, with shares falling more than 13% on news that Liberty Media (NASDAQ:QVCA), which purchased a large stake in Barnes and Noble three years ago, will now be selling 90% of that stake. Is this the beginning of the end for the embattled book retailer?

In this segment from Thursday's Investor Beat, host Chris Hill and Motley Fool analyst Jason Moser discuss Barnes and Noble, and the failure of the Nook. Jason sees the nook as something that will one day soon be completely edged out by the competition, but he also gives several good reasons why the actual book stores for Barnes and Noble aren't done yet, and why the company can still stay afloat if it shifts its focus back to these core competencies.
