Amazon.com introduced the Kindle. This unconventially-named ebook reader differed from other ebook readers because it incorporated a wireless service for purchasing and delivering electronic texts from Amazon.com without a computer. The 6 inch wide electronic-paper screen was limited to grayscale at 167ppi resolution. At its introduction 90,000 titles were available for download to the 10 oz. device. The first Kindle could store about 200 books.
