== Etymology ==
The word "yahoo" is a [[backronym]] for "[[Yet another|Yet Another]] Hierarchically Organized Oracle"<ref>{{cite news |work=[[Network World]] |title=Hello, Is Anyone Out There? |url=https://books.google.com/books?id=pw4EAAAAMBAJ&pg=RA1-PA40 |date=September 11, 1995 |last=Gaffin |first=Adam |access-date=March 5, 2015 |archive-date=May 14, 2015 |archive-url=https://web.archive.org/web/20150514163028/https://books.google.com/books?id=pw4EAAAAMBAJ&pg=RA1-PA40 |url-status=live }}</ref> or "Yet Another Hierarchical Officious Oracle".<ref>{{cite news | url=https://www.lifewire.com/what-does-yahoo-stand-for-2483337 | title=What Does "Yahoo" Stand For? | first=Paul | last=Gil | work=[[Lifewire]] | date=April 19, 2021 | access-date=May 4, 2021 | archive-date=October 7, 2016 | archive-url=https://web.archive.org/web/20161007112246/http://netforbeginners.about.com/od/internet101/f/yahoostory.htm | url-status=live }}</ref> The term "hierarchical" described how the Yahoo database was arranged in layers of subcategories. The term "oracle" was intended to mean "source of truth and wisdom", and the term "officious", rather than being related to the word's normal meaning, described the many office workers who would use the Yahoo database while surfing from work.<ref>{{cite web |title=What Does 'Yahoo' Stand For? |url=http://netforbeginners.about.com/od/internet101/f/yahoostory.htm |last=Gurnitsky |first=Joanna |work=About.com |access-date=July 2, 2012 |url-status=live |archive-url=https://web.archive.org/web/20120411035134/http://netforbeginners.about.com/od/internet101/f/yahoostory.htm |archive-date=April 11, 2012}}</ref> However, founders Filo and Yang insist they mainly selected the name because they liked the slang definition of a "yahoo" (used by college students in David Filo's native Louisiana in the late 1980s and early 1990s to refer to an unsophisticated, rural Southerner): "rude, unsophisticated, uncouth."<ref>{{cite web|url=http://docs.yahoo.com//info//misc//history.html|title=The History of Yahoo! – How It All Started ... |date=January 9, 2011 |publisher=Yahoo |archive-url=https://web.archive.org/web/20110109042907/http://docs.yahoo.com//info//misc//history.html|archive-date=January 9, 2011}}</ref> This meaning derives from the [[Yahoo (Gulliver's Travels)|Yahoo]] race of fictional beings from ''[[Gulliver's Travels]]''.

===Founding===
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]]"&mdash;both named after legendary [[sumo wrestler]]s. 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.
 
Yahoo was incorporated on March 2, 1995. In 1995, a [[search engine]] function, called Yahoo Search, was introduced. This allowed users to search Yahoo Directory.<ref>{{cite book |last1=Oppitz |first1=Marcus |last2=Tomsu |first2=Peter |title=Inventing the Cloud Century: How Cloudiness Keeps Changing Our Life, Economy and Technology |date=2017 |publisher=[[Springer Science+Business Media]] |isbn=9783319611617 |page=238 |url=https://books.google.com/books?id=vrEvDwAAQBAJ&pg=PA238 |access-date=September 5, 2019 |archive-date=February 26, 2020 |archive-url=https://web.archive.org/web/20200226023631/https://books.google.com/books?id=vrEvDwAAQBAJ&pg=PA238 |url-status=live }}</ref><ref>{{cite web |title=Yahoo!

As Yahoo's popularity has increased, so has the range of features it offers, making it a kind of one-stop shop for all the popular activities of the Internet. These now include: [[Yahoo! Mail]], a [[webmail|Web-based e-mail]] service, [[Yahoo! Messenger|an instant messaging client]], a very popular [[Electronic mailing list|mailing list]] service ([[Yahoo! Groups]]), online gaming and chat, various news and information portals, online shopping and [[auction]] facilities. Many of these are based at least in part on previously independent services, which Yahoo has acquired - such as the popular [[GeoCities]] free Web-hosting service, [[Rocketmail]], and various competing [[Electronic mailing list|mailing list]] providers such as [[eGroups]]. Many of these take-overs were controversial and unpopular with users of the existing services, as Yahoo often changed the relevant [[terms of service]]. An example of this would be their claiming [[intellectual property]] rights for the content on their servers, which the original companies had not done.
 
===Expansion===
At the pinnacle of the [[Internet]] boom in the year [[2000]], the cable news station [[CNBC]] reported that Yahoo! Inc. and [[eBay]] were in discussions to initiate a 50/50 merger [http://wired-vig.wired.com/news/business/0,1367,34967,00.html].

Beginning in late 2002, Yahoo quietly began to bolster its search services by acquiring competing technologies. In December 2002, it acquired [[Inktomi]], and in July 2003, it acquired [[Yahoo!

On [[February 18]], [[2004]], Yahoo dropped [[Google]]-powered results and returned to using its own technology to provide search results.

As of [[2005]] Yahoo!'s news message boards have gained something of a cult following. Attached to every story is a discussion board, yet rarely are the posts pertinent to the story. Often, the posts are deliberately outrageous, attempting to provoke angry responses which, in turn, lead to more offensive posts and so on. No news story, however sacrosanct, is spared.

In April 2005, [[Shi Tao]], a journalist working for a Chinese newspaper, was sentenced to 10 years in prison by the [[Changsa]] Intermediate People's Court of [[Hunan Province]], [[China]] (First trial case no 29), for "providing state secrets to foreign entities". He had passed details of a censorship order to the [[Asia]] [[Democracy]] Forum and the website [http://www.wmd.org/democracynews/may1102sup.html Democracy News]. [[Reporters Without Borders]] (RSF) investigated the case, specifically the ease with which Mr Tao had been caught. He had sent the message through an anonymous Yahoo! account. But police had gone straight to his offices and picked him up. RSF later obtained a translation of the [http://www.rsf.org/IMG/pdf/Verdict_Shi_Tao.pdf verdict] which stated that Mr Tao's account information, telephone number and address were "furnished by Yahoo! Holdings".
