Android is an operating system based on Linux kernel. It was designed primarily for mobile touchscreen devices such as smartphones and tablets; and for smartwatches, televisions and cars. It was initially developed by Android Inc., a company that Google supported financially and later, in 2005, bought. Android was introduced in 2007 with the founding of the Open Handset Alliance (a consortium of companies of hardware, software and telecommunications) for advancing open standards for mobile devices. The first phone with Android OS was the HTC Dream and was sold in October 2008. Android devices outsell the combined sales of Windows Phone and iOS.
