According to the Association of American Publishers (AAP), U.S. publishers' book sales across all platforms increased 2.4 percent in December 2010 versus December 2009 ($1.58 billion versus $1.54 billion), and 3.6 percent for all of 2010 versus 2009 ($11.67 billion versus $11.25 billion). Virtually every book publishing category showed growth in one or both comparisons, with e-books continuing to post triple-digit percentage gains.
"As more formats have evolved and are served by the publishing community, consumers have more choices. These strong sales numbers reflect the efforts of AAP publishers and the response of book audiences," says Tom Allen, AAP's president and CEO.
