Amazon.com introduced the Kindle on November 19, 2007. This unconventionally-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. There was no such thing as a first title available for the new Kindle since at launch 88,000 titles were available for download to the 10 oz. device. The first Kindle could store about 200 books.
