Googol officially known as ten-duotrigintillion or ten thousand sexdecillion is the number 10¹⁰⁰ (or Ten duotrigintillion) (10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000).

A 9-year-old Milton Sirotta, nephew of U.S. mathematician Edward Kasner, first used the word googol. Sirotta made this word in 1937, for the number represented by the numeral 1 followed by 100 zeros.He may have been inspired by the comic strip character Barney Google.

The company Google was named after the number "googol." Its creators originally called it BackRub because it used backlinks to tell how important each page was. Someone suggested "googolplex." They shortened it to "googol" and then spelled the word wrong when looking for a domain name that was not taken yet.
