An open source mobile operating system supported by the Tizen Association (formerly LiMo Foundation) and the Linux Foundation. Introduced in 2011 and evolving from the MeeGo OS and LiMo 4 framework, Tizen is based on Linux, HTML5 and WAC (Wholesale Applications Community). Samsung used Tizen in its second- and fourth-generation smartwatches (see Samsung Gear and Samsung Gear S), and at the Tizen Developer Conference in mid-2014, the first Tizen smartphone (Samsung Z) was introduced for the Russian market. Tizen-based in-vehicle systems from Intel and Tizen TVs from Samsung were also demonstrated. For more information, visit www.tizenassociation.org. See MeeGo, LiMo, HTML5 and WAC.
