High Quality Content by WIKIPEDIA articles! The Barnes & Noble Nook (styled "nook" or "NOOK") is a brand of e-reader developed by American book retailer Barnes & Noble, based on the Android platform. The original device was announced in the United States in October 2009, and was released the next month. The original Nook includes both Wi-Fi and AT&T 3G wireless connectivity, a six-inch E-paper display, and a separate, smaller color touchscreen that serves as the primary input device. A Wi-Fi-only model of the original design was released in June 2010. The original line of Nooks was followed in November 2010 by a color LCD device called the Nook Color, in June 2011 by a second-generation E-paper device marketed as the Nook Simple Touch, and in November 2011 and February 2012 by the 16GB and 8GB versions, respectively, of the Wi-Fi only Nook Tablet. On April 30, 2012, Barnes & Noble entered into a partnership with Microsoft that will spin off the Nook and college businesses into a subsidiary. On August 28, 2012, Barnes and Noble announced partnerships with retailers in the UK, which began offering the Nook digital products to people in October 2012.
