In 1996, Larry Page and Sergey Brin, two PhD students at Stanford University, began working on a search engine called Backrub.
In 1997, the name of the search engine was changed to Google, a play on the word "googol," which is a mathematical term for the number represented by 1 followed by 100 zeros.
In 1998, Google was incorporated as a private company and moved its operations to a garage in Menlo Park, California.
In 2007, Google released the Android operating system for mobile devices.
In 2011, Google acquired Motorola Mobility for $12.5 billion.
In 2015, Google restructured itself to become a subsidiary of a new parent company called Alphabet Inc.
