More people are reading books on e-readers. A new survey by the Pew Internet & American Life Project found nearly a quarter of all Americans older than 16 now use e-readers. At the same time, the number of consumers who read a printed book in the previous 12 months fell from 72 percent to 67 percent.
The survey shows growth in e-book use is nearly even among men and women. The largest age group reporting e-book use is the 30-49 segment.
Amazon pioneered the e-book with the Kindle, in 2007. Barnes and Noble introduced an e-reader called the Nook in November 2009. And in April 2010 Apple changed the game with the introduction of the iPad tablet computer, which also operated as an e-reader.
