When the e-book reader was introduced, I worried that the arrival of this high-tech device would be the end of print. But the opposite has happened, according to a 2014 survey conducted by the Pew Research Center. Print remains America’s preferred way of reading.

That doesn't mean the e-book has died off or will disappear any time soon. In fact, the Pew survey had also found that the popularity of e-books is on the rise, due to an increase in device ownership. Fifty percent of Americans now own mobile device—a tablet or an e-book reader—for e-book reading. As a result, more places to shop for digital books have cropped up.
