E-books aren't just becoming increasingly popular. They also appear to be promoting reading habits among American adults.
So says new research from the Pew Internet and American Life Project, which states that about one-fifth of U.S. adults have read an e-book in the past year.
And if you expand that to include Americans over 16 who have used an e-reader device or app to read news articles or magazine-style features, the figure jumps to 43%.
