Android is a Linux-derived OS backed by Google, along with major hardware and software developers (such as Intel, HTC, ARM, Samsung, Motorola and eBay, to name a few), that forms the Open Handset Alliance. Released on November 5th 2007, the OS was well received from a number of developers upon its introduction. Android's releases prior to 2.0 (1.0, 1.5, 1.6) were used exclusively on mobile phones. Android 3.0 was a tablet-oriented release and does not officially run on mobile phones. The current Android version is 4.2.2. Android's releases are Cupcake (1.5), Frozen Yogurt (2.2), Honeycomb (3.0), Ice Cream Sandwich (4.0) and Jelly Bean (4.1). Recent releases 4.0 and 4.1 were released keeping in mind a single OS for both phones and tablets. On November 15, 2011, Android reached 52.5% of the global smartphone market share.
