The Amazon Kindle is an ebook reader developed by Amazon.com subsidiary Lab126 which uses wireless connectivity to enable users to shop for, download, browse, and read ebooks, newspapers, magazines, blogs, and other digital media. The Kindle hardware devices use an E-Ink electronic paper display that shows up to 16 shades of gray, minimized power use and simulates reading on paper. In the last three months of 2010, Amazon announced that in the U.S., their ebook sales had surpassed sales of paperback books for the first time.
