Google is one of the richest companies in the world today, and one of the most influential technology companies of all time.

Over two decades ago, the company didn’t exist. But it has grown to a giant and on Monday, September 24th, celebrated its 20th birthday.

Within the 20-year period, the company has grown from simply a better way to explore the internet to a search engine so woven into daily life, its name has become a verb.

AFP reports that the company was set to mark its 20th anniversary with an event in San Francisco devoted to the future of online search, promising a few surprise announcements.

Here are 4 things you didn’t know about the search giant:

1. Google was founded by Larry Page and Sergey Brin when they were students at Stanford University when they came up with a way to efficiently index and search the internet.

The duo went beyond simply counting the number of times keywords were used, developing software that took into account factors such as relationships between webpages to help determine where they should rank in search results.

2. The search engine was officially launched in September 1998 in a garage rented in the Northern California city of Menlo Park. Have you ever thought of how they came by the name, Google? Well, the name is a play on the mathematical term "googol," which refers to the number 1 followed by 100 zeros.

3. Google reportedly ran for a while on computer servers at Stanford, where a version of the search had been tested. And Silicon Valley legend has it that the founder duo, Brin and Page offered to sell the company early on for a million dollars or so, but no deal came together. Imagine if they had found a willing investor to buy the company.

4. In August 2004, Google went public on the stock market with shares priced at $85. Shares in the multi-billion-dollar company are now trading above $1,000.

Its early code of conduct included a now-legendary "don't be evil" clause. Its stated mission is to make the world's information available to anyone.
