Sergey Brin met Larry Page at Stanford University. Despite initial disagreements, they began collaborating on a research project focused on developing a new kind of search engine.

Brin and Page initially called their search engine project 'BackRub,' reflecting its analysis of backlinks to understand website importance.

The name 'BackRub' was changed to 'Google,' a play on the mathematical term 'googol,' representing the vast amount of information the search engine aimed to organize.

Sergey Brin and Larry Page officially founded Google Inc. They initially operated out of Susan Wojcicki's garage in Menlo Park, California.

Andy Bechtolsheim, co-founder of Sun Microsystems, wrote a check for $100,000 to 'Google Inc.,' even before the company was formally incorporated. This marked the beginning of Google's rapid growth. The search engine rapidly gained popularity for its speed and accuracy.

As Google expanded, it moved to a larger office complex in Mountain View, California, which became known as the 'Googleplex'.

Google went public on August 19, 2004. The IPO was a significant event, valuing the company at billions of dollars and making Brin and Page billionaires.

Brin stepped down from the day-to-day operations of Google to focus on special projects.

Google underwent a major restructuring, becoming a subsidiary of a new holding company called Alphabet Inc. Brin became the President of Alphabet, focusing on innovation and new ventures.

Brin stepped down as President of Alphabet, remaining a controlling shareholder. Sundar Pichai became the CEO of both Google and Alphabet.
