6 endangered brands

They were household names for decades, and they still hold an important place in our collective consciousness. But these once-bright business stars are dimming, and may soon fade out entirely.

Barnes & Noble

Books printed on paper are rapidly becoming a novelty, so Barnes & Noble (BKS)'s best shot at staying relevant is its Nook e-reader, which is faring poorly against Amazon's (AMZN) Kindle.

The company's total revenue for the critical holiday season in 2013 fell 10 percent, while sales of Nook devices and accessories fell more than 50% from the year before.

Even founder Leonard Riggio looks like he's ready to close the book on things -- in the last year, he's unloaded a third of his shares in the company.
