1. What’s a Google?

 “Googol” is the mathematical term for a 1 followed by 100 zeros. The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, “Mathematics and the Imagination” by Kasner and James Newman. Google’s play on the term reflects the company’s mission to organize the immense amount of information available on the web.

2. Story behind Yahoo 

The Web site started out as “Jerry and David’s Guide to the World Wide Web” but eventually received a new moniker with the help of a dictionary. The name Yahoo! is an acronym for “Yet Another Hierarchical Officious Oracle,” but Filo and Yang insist they selected the name because they liked the general definition of a yahoo: “rude, unsophisticated, uncouth.” Yahoo! itself first resided on Yang’s student workstation, “Akebono,” while the software was lodged on Filo’s computer, “Konishiki” - both named after legendary sumo wrestlers.

3. ICQ

  ICQ is an instant messaging computer program, owned by Time Warner’s AOL subsidiary. The first version of the program was released in November 1996. The name ICQ is a play (an oronym) on the phrase “I seek you”.

 4. Orkut

Orkut is an Internet social network service run by Google and named after its creator, Google employee Orkut Büyükkökten. It claims to be designed to help users meet new friends and maintain existing relationships. Similar to Friendster and MySpace, Orkut goes a step further by permitting the creation of easy-to-setup simple forums (called “communities”) of users. Until recently, Orkut was invitation only, but it now permits users to create accounts without an invitation.
