Google began in 1995 as a search engine called "BackRub," so named for its ability to determine how many links were pointing back to a particular Web site.
A short time later, the name Google was derived from the mathematical term Googol, a number that is equivalent to the number one followed by 100 zeros.
The name 'Google' was an accident. A spelling mistake made by the original founders who thought they were going for 'Googol'
The prime reason the Google home page is so bare is due to the fact that the founders didn't know HTML and just wanted a quick interface
The infamous "I feel lucky" is nearly never used. However, in trials it was found that removing it would somehow reduce the Google experience. Users wanted it kept. It was a comfort button.
