In November 2007, Amazon launched the Kindle, an e-reader which downloads content over "Whispernet", via Sprint's EV-DO wireless network. The screen uses E Ink technology to reduce battery consumption and to provide a more legible display. As of July 2014, there are over 2.7 million e-books available for purchase at the Kindle Store. Starting in 2012 Amazon began offering differing models within generations of its readers starting with the Paperwhite, Voyage, and most recently the Oasis 2 released in October 2017.
In August 2007, Amazon announced AmazonFresh, a grocery service offering perishable and nonperishable foods. Customers could have orders delivered to their homes at dawn or during a specified daytime window. Delivery was initially restricted to residents of Mercer Island, Washington, and was later expanded to several ZIP codes in Seattle proper. AmazonFresh also operated pick-up locations in the suburbs of Bellevue and Kirkland from summer 2007 through early 2008.
