In recent years the world of publishing and book sales has undergone revolutionary change. The number of books printed on-demand has overtaken those printed conventionally. Almost 300,000 books were published using traditional methods in 2009, according to Books in Print, while in the same year about 765,000 were printed on-demand from the Internet. And the 2008 U.S. Book Consumer Demographics and Buying Behaviors Annual Report notes that 21 percent of book buyers said they became aware of a book through some sort of online promotion or advertisement. Census statistics from 2007 report that 61 percent of book and magazine purchases were made online and the conventional wisdom in the publishing industry is that the percentage of online sales has only grown since then.
