History
Acquisition by Google
In July 2005, Google acquired Android, Inc., a small startup company based in Palo Alto, California, USA. Android's co-founders who went to work at Google included Andy Rubin (co-founder of Danger), Rich Miner (co-founder of Wildfire Communications, Inc.),[20] Nick Sears (once VP at T-Mobile),[21] and Chris White (headed design and interface development at WebTV).[22] At the time, little was known about the functions of Android, Inc. other than that they made software for mobile phones.[18] This began rumors that Google was planning to enter the mobile phone market.At Google, the team led by Rubin developed a mobile device platform powered by the Linux kernel which they marketed to handset makers and carriers on the premise of providing a flexible, upgradable system. It was reported that Google had already lined up a series of hardware component and software partners and signaled to carriers that it was open to various degrees of cooperation on their part.[23][24][25] More speculation that Google would be entering the mobile-phone market came in December 2006.[26] Reports from the BBC and The Wall Street Journal noted that Google wanted its search and applications on mobile phones and it was working hard to deliver that. Print and online media outlets soon reported rumors that Google was developing a Google-branded handset.[27] More speculation followed reporting that as Google was defining technical specifications, it was showing prototypes to cell phone manufacturers and network operators.
In September 2007, InformationWeek covered an Evalueserve study reporting that Google had filed several patent applications in the area of mobile telephony.[28][29]

On 9 December 2008, it was announced that 14 new members would be joining the Android project, including PacketVideo, ARM Holdings, Atheros Communications, Asustek Computer Inc, Garmin Ltd, Softbank, Sony Ericsson, Toshiba Corp, and Vodafone Group Plc.[30][31]
Licensing
With the exception of brief update periods, Android has been available under a free software / open source license since 21 October 2008. Google published the entire source code (including network and telephony stacks)[32] under an Apache License.[33]With the Apache License, vendors can add proprietary extensions without submitting those back to the open source community.
