Publishers need to focus on the 19 percent. Graphic designer Boris Benko created a sprawling infographic (embedded below) visualizing recent trends in digital reading.
According to the research, 19 percent of U.S. adults own eReaders and 19 percent of U.S. adults own tablets. While both markets were practically nonexistent in 2009, they have become a booming marketplace for publishers.
In addition, the graphic breaks down tablet and eReader ownership by gender and race, providing an interesting snapshot of this new audience.
