America's obsession with digital tablets is driving a boom in e-book reading, a new survey shows, a trend that is dampening the appeal of printed books and shaking the centuries-old publishing business.

The share of Americans who read e-books grew to 23 percent from 16 percent in 2012, while the number of adults who read printed books fell to 67 percent from 72 percent, according to a study released Thursday by the Pew Internet & American Life Project.

The swift and dramatic shift in reading habits was brought on by the rising popularity of tablets and e-reader devices, which are now owned by one-third of the U.S. population, the survey showed.
