History and growth
Early history (1994–1999)
In January 1994, Jerry Yang and David Filo were Electrical Engineering graduate students at Stanford University. In April 1994, "Jerry and David's Guide to the World Wide Web" was renamed "Yahoo!", for which the official is "Yet Another Hierarchical Officious Oracle". Filo and Yang said they selected the name because they liked the word's general meaning, which comes from Gulliver's Travels by Jonathan Swift: "rude, and ". Its URL was akebono.stanford.edu/yahoo. Yang describes their selection of the name as "We thought it fit well with what we were doing. It was irreverent. It was reflective of the Wild West nature of the Internet. A lot of people found it easy to remember, and besides, it's exactly what me and Jerry are.a couple of yahoos."
