Kin was a short-lived mobile phone line from Microsoft designed for users of social networking. The phones, aimed at people between ages 15 and 30, were manufactured by Sharp Corporation and sold through Verizon Wireless.
Microsoft invested two years and about US$1 billion developing the Kin platform, beginning with its acquisition of Danger Incorporated. The Kin was based on Windows CE.
The Kin ONE and TWO went on the market on May 14, 2010. Within two months, Verizon stopped selling the phones because of poor sales. Microsoft scrapped its planned European release, stopped promoting the devices, ceased production, and reassigned the Kin development team to other projects.
Microsoft updated its unsold Kin inventory with firmware that removed social and web-based features, and in December 2010 offered these re-purposed units through Verizon stores as limited feature phones, the Kin ONEm and the TWOm. In January 2011, Microsoft shut down the kin.com website, which controlled most of the earlier phones' features.
The Kin TWOm was discontinued in August 2011; unsold inventory could still be found for sale on deals sites as late as June 2013.
