Android, Inc. was founded in Palo Alto, California in October 2003 by Andy Rubin (co-founder of Danger), Rich Miner (co-founder of Wildfire Communications, Inc.), Nick Sears (once VP at T-Mobile), and Chris White (headed design and interface development at WebTV) to develop. Google acquired Android Inc. on August 17, 2005, making it a wholly owned subsidiary of Google. Key employees of Android Inc., including Rubin, Miner and White, stayed at the company after the acquisition. Not much was known about Android Inc. at the time, but many assumed that Google was planning to enter the mobile phone market with this move. At Google, the team led by Rubin developed a mobile device platform powered by the Linux kernel. Google marketed the platform to handset makers and carriers on the promise of providing a flexible, upgradable system. Google had 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. Speculation about Google's intention to enter the mobile communications market continued to build through December 2006. 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. Android was unveiled as its first product, a mobile device platform built on the Linux kernel version 2.6. The first commercially available phone to run Android was the HTC Dream, released on October 22, 2008. Since 2008, Android has improved the operating system, adding new features and fixing bugs in previous releases. Each major release is named in alphabetical order ,for example, version 1.5 Cupcake was followed by 1.6 Donut. The latest release is 4.2 Jelly Bean. In 2010, Google launched its Nexus series of devices - a line of smart phones and tablets running the Android operating system, and built by a manufacturer partner. HTC collaborated with Google to release the first Nexus smart phone, the Nexus One. The series has since been updated with newer devices, such as the Nexus 4 phone and Nexus 10 tablet, made by LG and Samsung respectively. Google releases the Nexus phones and tablets to act as their flagship Android devices, demonstrating Android's latest software and hardware features. History of iOS (iPhone Operating System)
The operating system was unveiled with the iPhone in January 9, 2007, and released in June of that year. At first, Apple did not specify a separate name for the operating system, stating simply that the "iPhone runs OS X”. On October 17, 2007, Apple announced that a native Software Development Kit (SDK) was under development and that they planned to put it "in developers' hands in February". On March 6, 2008, Apple released a new name for the operating system: "iPhone OS". Apple had released the iPod touch, which had most of the non-phone capabilities of the iPhone. Apple also sold more than one million iPhones during the 2007 holiday season.]On January 27, 2010, Apple announced the iPad, featuring a larger screen than the iPhone and iPod touch, and designed for web browsing, media consumption, and reading iBooks. In June 2010, Apple rebranded iPhone OS as "iOS". The trademark "IOS" had been used by Cisco .To avoid any potential lawsuit, Apple licensed the "IOS" trademark from Cisco. By late 2011, iOS accounted for 60 percent of the market share for smartphones and tablet computers, however by mid 2012 iOS had slipped to just 16.9% of the Smartphone market and Android had taken over with 68.1% global share. Since the release of the iPhone 5 this has again changed with both operating systems about equal for Smartphones, with iOS well ahead in Tablets and portable music devices.
