Yahoo! Inc. is an American computer services company with a mission to "be the most essential global Internet service for consumers and businesses". It operates an Internet portal, a web directory and a host of other services including the popular Yahoo! Mail. It was founded by Stanford graduate students David Filo and Jerry Yang in January 1994 and incorporated on March 2, 1995. The company is headquartered in Sunnyvale, California.
Yahoo! started out as "Jerry'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, as in Gulliver's Travels by Jonathan Swift: "rude, unsophisticated, uncouth." Yahoo itself first resided on Yang's student workstation, "Akebono," while the software was lodged on Filo's computer, "Konishiki"óboth named after legendary sumo wrestlers. The "yet another" phrasing goes back at least to the Unix utility yacc, whose name is an acronym for "yet another compiler compiler".
Yahoo had its initial public offering on April 12, 1996, selling 2.6 million shares at $13 each.
