Android was founded in 2003 by Andy Rubin, Rich Miner, Nick Sears, and Chris White to develop an advanced operating system. In 2005, Google acquired Android and in 2007 unveiled Android 1.0. The first commercially available Android device was the HTC Dream in 2008. Android has since grown to become the world's most popular mobile operating system, powering a wide variety of phones and tablets from many manufacturers.
