For Kindle Android tablets, see Kindle Fire
An e-book system from Amazon.com that includes a family of portable e-readers and a vast library of e-books. Introduced in 2007 with 88,000 titles and more than a hundred best sellers, the Kindle has defined the e-book industry. Kindle devices have become thinner, lighter and brighter, and the book selection continually increases (more than one million by 2015). Titles are searched and purchased on the Kindle and immediately downloaded via Amazon's WhisperNet via Wi-Fi or cellular, depending on model and geographic area. Newspapers and magazines are sent overnight for morning reading.
Featuring models with 6" and 10" screens, Web access and music playback on earlier models was later dropped (all of which are available on Kindle Fire tablets). The Kindle's monochrome E Ink display enables the battery to last up to a month. See Kindle Fire
