History of Google Android OS

Android is a mobile operating system; it is based on modified Linux kernel and alternative open source software. Android is developed by a consortium of developers known as the (OHA)Open Handset Alliance, with the main contributor being Google.

It was originally founded and developed by Andy Rubin, Rich Miner and Nick Sears under the name “Android, Inc”.

Android Inc. was to develop “smarter mobile devices that are more aware of its owner’s location and preferences.” Andy Rubin further stated, “If people are smart, that information starts getting aggregated into consumer products.” The year was 2003 and the location was Palo Alto, California. This was the year Android was born.

In July 2005 Google acquired Android Inc. for $50 million and Its key employees, including Rubin, Miner and White, joined Google as part of the acquisition.
