The Nook Tablet (sometimes styled NOOK Tablet) is a tablet e-reader/media player that was produced and marketed by Barnes & Noble. It followed the Nook Color and was intended to compete with both e-book readers and tablet computers. According to estimates by Forrester Research, about 5 million units were sold by mid-October 2012, making the Nook Tablet the third best selling tablet after Apple's iPad and Amazon's Kindle Fire in 2012.
