The e-book market is booming while the brick-and-mortar book market is rapidly declining. In 2013, Amazon.com released the 6th generation of the Kindle reader – the “Kindle Paperwhite” (also known as‘Paperwhite 2’).” Kindle books can also be read on virtually every PC or tablet device. Barnes & Noble has a Kindle competitor called the Nook. The result is that some categories of books in digital format sell better than their hardcover and paperback counterparts, as described in Chap. 5.
