Android (operating system)

Android Inc. was founded in Palo Alto, California, in October 2003 by Andy Rubin and Chris White, with Rich Miner and Nick Sears joining later. Rubin had previously been the creator of the T-Mobile Sidekick under his previous company Danger, Inc. Rubin and White started out to build an operating system for digital cameras viz FotoFrame.

com. After having built a prototype internally known as the "Fadden demo" predominantly by purchasing licensing agreements for most of the software components built around a custom JavaScript front-end, the company failed to convince investors, and so in April 2004 they pivoted to building an operating system for phones at the suggestion of Nick Sears, as a rival to Symbian and Microsoft Windows Mobile. Rubin pitched the Android project as having "tremendous potential in developing smarter mobile devices that are more aware of its owner's location and preferences". Due to difficulty attracting investors early on, Android faced potential eviction from its office space.

Android received a lukewarm reaction when it was unveiled in 2007. Although analysts were impressed with the respected technology companies that had partnered with Google to form the Open Handset Alliance, it was unclear whether mobile phone manufacturers would be willing to replace their existing operating systems with Android. The idea of an open-source, Linux-based development platform sparked interest, but there were additional worries about Android facing strong competition from established players in the smartphone market, such as Nokia and Microsoft, and rival Linux mobile operating systems that were in development. These established players were skeptical: Nokia was quoted as saying "we don't see this as a threat", and a member of Microsoft's Windows Mobile team stated "I don't understand the impact that they are going to have."

Since then Android has grown to become the most widely used smartphone operating system and "one of the fastest mobile experiences available". Reviewers have highlighted the open-source nature of the operating system as one of its defining strengths, allowing companies such as Nokia (Nokia X family), Amazon (Kindle Fire), Barnes & Noble (Nook), Ouya, Baidu and others to fork the software and release hardware running their own customised version of Android. As a result, it has been described by technology website Ars Technica as "practically the default operating system for launching new hardware" for companies without their own mobile platforms. This openness and flexibility is also present at the level of the end user: Android allows extensive customisation of devices by their owners and apps are freely available from non-Google app stores and third party websites. These have been cited as among the main advantages of Android phones over others.
