Amazon Kindle is a software and hardware platform developed by Amazon.com subsidiary Lab126 for reading e-books and other digital media. Three hardware devices, known as "Kindle", "Kindle 2," and "Kindle DX" support this platform, as does an iPhone application called "Kindle for iPhone". The first device was released in the United States on November 19, 2007.

The Kindle hardware devices use E Ink brand electronic paper displays, and are able to download content over Amazon Whispernet using the Sprint EVDO network. Kindle hardware devices can be used without a computer, and Whispernet is accessible without any fee. These devices also provide free internet access to Wikipedia. The Kindle is not available outside the US due to import/export laws and other restrictions.

On March 3, 2009, Amazon.com launched an application entitled Kindle for iPhone in the App Store for iPhone and iPod Touch owners to read Kindle content. Through a technology termed "Whispersync," customers can keep their place across Kindle hardware devices and other mobile devices.

Amazon announced the Kindle DX on May 6, 2009. This device has a larger screen than its predecessors and supports PDF files natively. It is marketed as more suitable for displaying newspaper and textbook content.
