Although electronic books, or e-books, had limited success in the early years, and readers were resistant at the outset, the demand for books in this format has grown dramatically, primarily because of the popularity of e-reader devices and as the number of available titles in this format has increased. Since the Amazon Kindle was released in 2007, the e-book has become a digital phenomenon and many theorize that it will take over hardback and paper books in future. E-books are much more accessible and easier to buy and it’s also cheaper to purchase an E-Book rather than its physical counterpart due to paper expenses being deducted.[24] Another important factor in the increasing popularity of the e-reader is its continuous diversification.
