Now,
there are signs that some e-book adopters are returning to print, or
becoming hybrid readers, who juggle devices and paper. E-book sales fell
by 10 percent in the first five months of this year, according to the
Association of American Publishers, which collects data from nearly
1,200 publishers. Digital books accounted last year for around 20
percent of the market, roughly the same as they did a few years ago. E-books’
declining popularity may signal that publishing, while not immune to
technological upheaval, will weather the tidal wave of digital
technology better than other forms of media, like music and television.
