Technology and mobility have influenced every step of consumer’s life, including the way they read books. Book readers have started to change their reading habits, opting for different types of formats of books, such as e-books. An e-book, also known as an electronic or digital book, is a digitally released version of a book, often consisting of text and images and available on electronic devices, such as specifically designed e-book readers. This shift in media consumption habits has a direct impact in the book industry. The e-book industry is here to stay, showing healthy projections. By 2018, e-book sales are forecast to account for about a quarter of global book sales. Consumer e-books alone are projected to generate nearly 20 billion U.S. dollars in revenue by 2018.
