With incomplete data accessible for the whole 12 months, by the end of 2012, a rather complicated image took shape. Unit sales of print publications had fallen over 9% according to Nielsen BookScan, continuing the decline found a year before, from 2010 to 2011 (, Publishers Weekly, 6 January 2013]). Print sales were mainly driven by several bestselling names, notably E.L. James' Fifty Shades of Grey trilogy with 14.4 million print units sold, followed by Suzanne Collins' Hunger Games novels with 9.6 million. "Collectively, both of these writers accounted for over 4 percent of all print revenues for the year" (data from Nielsen BookScan, quoted in PublishersLunch, 7 January 2013]). In spite of the decline in print, according to the American Association of Publishers (AAP), predicated on data from September 2012, the total bookmarket represented "the tendencies we have seen all year: continued publishing increase overall with substantial increases in kids's/young adult (particularly eBook format) and minor erosion in faith publishing" ("StatShot" for September 2012, quoted in PublishersLunch, 25 January 2013).
"The eBook happening continued in 2012 with eBooks position, for the very first time, as the year's number 1 individual format for Adult Fiction" was the headline in the BookStats report on US publishing in 2011, issued jointly by the Association of American Publishers (AAP) as well as the Book Industry Study Group (BISG) in July 2012. The $27.2 billion 2011 US publication market fell by 2.5 from $27.94 billion in 2011, while unit sales grew by 3.4%, as did the amount of new print titles, from 328,259 million in 2010 to a projected 347,178 million in 2011 (, Bowker, 5 June 2012).
