"The name 'Google' is a play on the word 'googol,' coined by Milton Sirotta, nephew of American mathematician Edward Kasner. A 'googol' refers to the number represented by a 1 followed by 100 zeros. It's a very large number. In fact, there isn't a googol of anything in the universe -- not stars, not dust particles, not atoms. Google's use of the term reflects our mission to organize the world's immense (seemingly infinite) amount of information and make it universally accessible and useful," Google tried to explain the origins of the company's name.
