The Amazon Kindle is a series of e-book readers now in its fourth generation. Amazon Kindle eReaders enable users to shop for, download, browse, and read e-books, newspapers, magazines, blogs, and other digital media via wireless networking. The hardware platform, developed by Amazon.com subsidiary Lab126, began as a single device and now comprises a range of devices — most using an E Ink electronic paper display capable of rendering 16 shades of gray to simulate reading on paper while minimizing power consumption.

The Kindle name was devised by branding consultant Michael Cronan who was asked by Lab 126 to name the product. Cronan and partner Karin Hibma suggested Kindle. Deriving from Old Norse kynda "to light a fire", they felt this was an apt metaphor for reading and intellectual excitement.

Kindle hardware has evolved from the original Kindle introduced in 2007 and a Kindle DX line (with a larger screen) introduced in 2009. Announced in September 2011, the range now includes devices with keyboards (Kindle Keyboard), devices with touch sensitive screens (Kindle Touch), a tablet computer with a reader app and a color display (Kindle Fire) and a low-priced model with an on-screen keyboard (Kindle).
