The 21st century has brought a number of new technological changes to the publishing industry. These changes include e-books, print on demand and accessible publishing. E-books have been quickly growing in availability since 2005. Google, Amazon.com and Sony have been leaders in working with publishers and libraries to digitize books. As of early 2011 Amazon's Kindle reading device is a significant force in the market, along with the Apple iPad and the Nook.
