Yahoo! was founded in January 1994 by Jerry Yang and David Filo, who were electrical engineering graduates at Stanford University when they created a website named "Jerry and David's Guide to the World Wide Web". The Guide was a directory of other websites, organized in a hierarchy, as opposed to a searchable index of pages. In April 1994, Jerry and David's Guide to the World Wide Web was renamed "Yahoo!".{{cite book |title=Blueprint to a Billion |author=David G.

Yahoo! grew rapidly through 1990–1999 and diversified into a web portal, followed by numerous high-profile acquisitions. The company's stock price rose rapidly during the dot-com bubble and closed at an all-time high of US$118.75 in 2000.{{cite web|title=Yahoo: An 18-year timeline of events|url=http://performancein.com/news/2012/07/17/yahoo-18-year-timeline-events/|work=PerformanceIN|access-date=27 May 2013|author=Simon Holland|date=July 2012|archive-url=https://web.archive.org/web/20170810111851/http://performancein.com/news/2012/07/17/yahoo-18-year-timeline-events/|archive-date=August 10, 2017|url-status=dead}} However, after the dot-com bubble burst, it reached an all-time low of $8.11 in 2001.{{cite book|last=Linder|first=Karen|author-link=Karen Linder|title=The Women of Berkshire Hathaway|url=https://books.google.com/books?id=V_r3vM8y4-QC&pg=PA199|access-date=27 May 2013|year=2012|publisher=John Wiley & Sons|location=Hoboken, New Jersey|isbn=9781118182628|page=199|quote=Shortly after the 9/11 attacks, on September 26, 2001, Yahoo!'s stock hit its all-time low of $8.11.|archive-date=April 21, 2024|archive-url=https://web.archive.org/web/20240421144438/https://books.google.com/books?id=V_r3vM8y4-QC&pg=PA199#v=onepage&q&f=false|url-status=live}} Yahoo! formally rejected an acquisition bid from the Microsoft Corporation in 2008.{{cite news|url=http://news.bbc.co.uk/1/hi/business/7239220.stm|title=Yahoo rejects Microsoft approach|publisher=BBC News Online|access-date=2008-02-17|date=February 11, 2008|archive-date=February 14, 2008|archive-url=https://web.archive.org/web/20080214180223/http://news.bbc.co.uk/1/hi/business/7239220.stm|url-status=live}} In early 2012, Yahoo laid off 2,000 employees (14 percent of the workforce).

Early history (1994–1996)

When Jerry and David's Guide to the World Wide Web was renamed to Yahoo! in 1994, Yang and Filo said that "Yet Another Hierarchical Officious Oracle" was a suitable backronym for this name, but they insisted they had selected the name because they liked the word's general definition, as in Gulliver's Travels by Jonathan Swift: "rude, unsophisticated, uncouth." Its URL was akebono.stanford.edu/~yahoo.

The yahoo.com domain was created in January 1995, although by the end of 1994 Yahoo! had already received one million hits. Yang and Filo realized their website had massive business potential, and on March 2, 1995, Yahoo! was incorporated.{{cite web |title=Inventing Yahoo! |author=David Rapp |year=2006 |url=http://www.americanheritage.com/events/articles/web/20060412-yahoo-internet-search-engine-jerry-yang-david-filo-america-online-google-ipo-email.shtml |publisher=American Heritage |access-date=2008-02-22|archive-date=July 16, 2010 |archive-url=https://web.archive.org/web/20100716081021/http://www.americanheritage.com/events/articles/web/20060412-yahoo-internet-search-engine-jerry-yang-david-filo-america-online-google-ipo-email.shtml}}

Yang and Filo sought the advice of entrepreneur Randy Adams for a recommendation of a venture capital firm, and Adams introduced them to Michael Moritz.{{cite news |url=https://books.google.com/books?id=iOm_hPc8IMwC&q=randy+adams+yahoo+Jerry+Yang&pg=PA30 |title=Jerry Yang and David Filo |isbn=9780761319610 |last1=Sherman |first1=Josepha |date=January 2001 |publisher=Twenty-First Century Books |access-date=October 26, 2020 |archive-date=April 21, 2024 |archive-url=https://web.archive.org/web/20240421144350/https://books.google.com/books?id=iOm_hPc8IMwC&q=randy+adams+yahoo+Jerry+Yang&pg=PA30#v=snippet&q=randy%20adams%20yahoo%20Jerry%20Yang&f=false |url-status=live }} On April 5, 1995, Michael Moritz of Sequoia Capital provided Yahoo! with two rounds of venture capital, raising approximately $3 million.{{cite news |author=Eric Schmidt |author-link=Eric Schmidt |url=http://www.time.com/time/specials/2007/time100/article/0,28804,1595326_1615737_1616199,00.html |archive-url=https://web.archive.org/web/20070505050506/http://www.time.com/time/specials/2007/time100/article/0,28804,1595326_1615737_1616199,00.html |url-status=dead |archive-date=May 5, 2007 |title=The Time 100 – Michael Moritz |publisher=Time |access-date=2008-11-08 |date=May 3, 2007}}{{cite web |url=http://yhoo.client.shareholder.com/press/timeline.cfm|archive-url=https://web.archive.org/web/20080213120416/http://yhoo.client.shareholder.com/press/timeline.cfm |archive-date=February 13, 2008 |title=Yahoo Company Timeline |access-date=2008-08-18}} On April 12, 1996, Yahoo! had its initial public offering, raising $33.8 million by selling 2.6 million shares at the opening bid of $13 each. The company's shares traded on Nasdaq under the ticker symbol YHOO.

The word "Yahoo" had previously been trademarked for barbecue sauce, knives (by EBSCO Industries) and human propelled watercraft (by Old Town Canoe Co.). Therefore, in order to get control of the trademark, Yang and Filo added the exclamation mark to the name.{{cite web|last=Welford|first=Barry|url=http://www.bpwrap.com/2004/04/a-rose-by-any-other-name/|title=A Rose By Any Other Name|publisher=BPWrap|date=30 April 2004|access-date=27 May 2013|archive-date=May 1, 2021|archive-url=https://web.archive.org/web/20210501211856/http://www.bpwrap.com/2004/04/a-rose-by-any-other-name/|url-status=live}} However, the exclamation mark is often incorrectly omitted when referring to Yahoo!. Srinija Srinivasan, an alumna of Stanford University, was hired as Yahoo!'s fifth employee as "Ontological Yahoo!" to assist Yang and Filo with organizing the content on the internet.{{Cite journal|url = https://www.wsj.com/news/articles/SB10001424052748704017904575409210554671690|title = Yahoo Executive Srinivasan to Leave|last = Letzing|first = John|date = August 10, 2010|journal = The Wall Street Journal|access-date = January 19, 2015|archive-date = January 19, 2015|archive-url = https://web.archive.org/web/20150119223615/http://www.wsj.com/news/articles/SB10001424052748704017904575409210554671690|url-status = live}}{{Cite magazine|url = http://archive.wired.com/wired/archive/4.05/indexweb.html?pg=2|title = Seek and Ye Shall Find (Maybe)|last = Steinberg|first = Steve|date = May 1996|magazine = Wired|access-date = January 19, 2015}}

Growth (1997–1999)

In the late 1990s, Yahoo!, MSN, Lycos, Excite, and other web portals were growing rapidly. Web portal providers moved to acquire companies to expand their range of services, generally with the goal of increasing the time each user stays within the portal.

On March 8, 1997, Yahoo! acquired online communications company Four11. Four11's webmail service, Rocketmail, became Yahoo! Mail. The company also acquired ClassicGames.com and re-branded it Yahoo! Games. Yahoo! acquired direct marketing company Yoyodyne Entertainment, Inc. on October 12, 1998.{{cite magazine | url=https://www.wired.com/news/business/0,1367,15555,00.html | magazine=Wired | title=Yahoo Acquiring Yoyodyne | date=October 12, 1998 | access-date=March 7, 2017 | archive-date=March 11, 2007 | archive-url=https://web.archive.org/web/20070311004241/http://www.wired.com/news/business/0,1367,15555,00.html | url-status=live }} In January 1999, Yahoo! acquired web hosting provider GeoCities. Yahoo! also acquired eGroups, which became Yahoo! Groups in June 2000. It acquired Pager,{{cite web |url=http://yhoo.client.shareholder.com/common/mobile/iphone/releasedetail.cfm?releaseid=173501&CompanyID=YHOO |archive-url=https://web.archive.org/web/20140313050941/http://yhoo.client.shareholder.com/common/mobile/iphone/releasedetail.cfm?releaseid=173501&CompanyID=YHOO |url-status=dead |archive-date=2014-03-13 |title=Stay in Touch With Yahoo! Pager |publisher=Yahoo |access-date=2008-12-08 }} an instant messaging service that was renamed Yahoo! Messenger a year later.

When acquiring companies, Yahoo! often changed the terms of service. For example, they claimed intellectual property rights for content on their servers, unlike the previous policies of the companies they acquired. As a result, many of the acquisitions were controversial and unpopular with users of the existing services.{{Cite web |title=Yahoo relents on GeoCities terms |url=https://www.cnet.com/tech/services-and-software/yahoo-relents-on-geocities-terms/ |access-date=2024-11-04 |website=CNET |language=en}}

Dot-com bubble (2000–2001)

Yahoo! stock doubled in price in the last month of 1999.{{cite web |title=YHOO: Historical Prices for Yahoo Inc – Yahoo!

Sixteen days later, shares in Yahoo!

Post dot-com bubble (2002–2005)

Yahoo! was one of the few surviving companies after the dot-com bubble burst. Nevertheless, on September 26, 2001, Yahoo! stock closed at an all-time low of $8.11.

Yahoo! formed partnerships with telecommunications and Internet providers to create content-rich broadband services to compete with AOL.

Yahoo! (2006–2008)

Yahoo! Next was an incubation ground for future Yahoo! technologies in their beta testing phase, similar to Google Labs. It contained forums for Yahoo! users to give feedback to assist in the development of these future Yahoo! technologies.

In early 2006, Yahoo! offered to users the opportunity to beta test a new version of the Yahoo! homepage. However, the test only had support for Internet Explorer and Mozilla Firefox browsers. Users of other browsers, such as Opera, have criticized Yahoo! for this move. Yahoo! says they intend to support additional browsers in the future.

On August 27, 2007, Yahoo! released a new version of Yahoo! Mail. It added Yahoo! Messenger integration (which included Windows Live Messenger due to the networks' federation) and free text messages (although not necessarily free to the receiver) to mobile phones in the U.S., Canada, India, and the Philippines.{{cite web |title=SiliconRepublic: Yahoo releases new email service |url=http://www.siliconrepublic.com/news/news.nv?storyid=single9082 |publisher=siliconrepublic.com |access-date=2008-02-25 |archive-url = https://web.archive.org/web/20071117094040/http://www.siliconrepublic.com/news/news.nv?storyid=single9082 |archive-date = November 17, 2007}}

On January 29, 2008, Yahoo! announced that the company was laying off 1,000 employees, as the company had failed to effectively compete with industry search leader Google.

Microsoft and Yahoo! were in merger discussions in 2005, 2006, and 2007, that were ultimately unsuccessful.

Analysts said that Yahoo!'s shares, which closed at $28.67 per share on May 2, were likely to drop below $25 per share and perhaps as low as $20 per share on May 5, which would put significant pressure on Yang to engineer a turnaround of the company.

On January 13, 2009, Yahoo! appointed Carol Bartz, former executive chairman of Autodesk, as its new chief executive officer and a member of the board of directors.{{cite web|last=Hof |first=Rob |url=http://www.businessweek.com/the_thread/techbeat/archives/2009/01/carol_bartz_to.html |archive-url=https://web.archive.org/web/20090119115137/http://www.businessweek.com/the_thread/techbeat/archives/2009/01/carol_bartz_to.html |url-status=dead |archive-date=January 19, 2009 |title=Confirmed: Carol Bartz Named Yahoo CEO: Can She Turn It Around? |publisher=BusinessWeek |date=January 13, 2009 |access-date=2012-10-19}}

Yahoo! wished to change its direction after chief executive Carol Bartz replaced co-founder Jerry Yang.

In July 2009, Microsoft and Yahoo! agreed to a deal that would see Yahoo!'s websites use both Microsoft's search technology and search advertising.{{cite web|last=Goldman|first=David|url=https://money.cnn.com/2009/07/29/technology/microsoft_yahoo/|title=Microsoft and Yahoo: Search partners|publisher=CNNMoney.com|date=29 July 2009|access-date=27 May 2013|archive-date=February 11, 2021|archive-url=https://web.archive.org/web/20210211070131/https://money.cnn.com/2009/07/29/technology/microsoft_yahoo/|url-status=live}} Yahoo! in turn became the sales team for banner advertising for both companies. While Microsoft would provide algorithmic search results, Yahoo! would control the presentation and personalization of results for searches on its pages.

On July 21, 2009, Yahoo! launched a new version of its front page, called Metro. The new page allowed users to customize it through the prominent "My Favorites" panel on the left side and integrate third-party web services and launch them within one page.[http://www.pcworld.com/article/168767/yahoo_home_page_gets_a_new_look.html Yahoo Home Page Gets A New Look] {{Webarchive|url=https://web.archive.org/web/20120422083606/http://www.pcworld.com/article/168767/yahoo_home_page_gets_a_new_look.html |date=April 22, 2012 }}.

On October 28, 2009, Bartz told PCWorld that she struggled with the question of what Yahoo! is when she took over as CEO in January 2009. After talking to many users in about 10 countries, she said, Yahoo! executives concluded that users consider it their "home on the Internet."[https://www.pcworld.com/article/174579/bartz_yahoo_wants_to_regain_respect.html Bartz: Yahoo Wants to Regain R-E-S-P-E-C-T]{{Dead link|date=August 2023 |bot=InternetArchiveBot |fix-attempted=yes }} PCWorld, October 28, 2009

In September 2011, Bartz sent an email to Yahoo! employees saying she was removed from her position at Yahoo! by the company's chairman Roy Bostock via a phone call.{{cite web |url=https://techcrunch.com/2011/09/06/carol-bartz-fired/ |title=Carol Bartz Confirms Her Own Firing – From Her iPad |publisher=TechCrunch |date=September 6, 2011 |access-date=2012-10-19 |archive-date=February 1, 2017 |archive-url=https://web.archive.org/web/20170201114432/https://techcrunch.com/2011/09/06/carol-bartz-fired/ |url-status=live }} CFO Tim Morse was named as Interim CEO of the company.{{cite web |url=http://allthingsd.com/20110906/exclusive-carol-bartz-out-at-yahoo-cfo-interim-ceo/ |title=Exclusive: Carol Bartz Out at Yahoo; CFO Tim Morse Named Interim CEO – Kara Swisher – News |publisher=AllThingsD |date=September 6, 2011 |access-date=2012-10-19 |archive-date=September 9, 2011 |archive-url=https://web.archive.org/web/20110909141710/http://allthingsd.com/20110906/exclusive-carol-bartz-out-at-yahoo-cfo-interim-ceo/ |url-status=live }}{{cite news | url=https://www.smh.com.au/business/world-business/yahoo-fires-ceo-after-tumultuous-tenure-20110907-1jwmu.html | work=The Sydney Morning Herald | title=Yahoo fires CEO after tumultuous tenure | date=September 7, 2011 | access-date=February 19, 2020 | archive-date=September 17, 2016 | archive-url=https://web.archive.org/web/20160917070830/http://www.smh.com.au/business/world-business/yahoo-fires-ceo-after-tumultuous-tenure-20110907-1jwmu.html | url-status=live }}

In early 2012, after the appointment of Scott Thompson as the new CEO, many rumors spread about large layoffs looming. Kara Swisher who covered Yahoo at All Things Digital reported that Yahoo's Chief Product Officer Blake Irving resigned,{{cite web |url=http://allthingsd.com/20120405/exclusive-yahoos-chief-product-officer-blake-irving-resigns/ |title=Exclusive: Yahoo's Chief Product Officer Blake Irving Resigns – Kara Swisher – News |publisher=AllThingsD |date=April 5, 2012 |access-date=2012-10-19 |archive-date=January 4, 2013 |archive-url=https://web.archive.org/web/20130104215900/http://allthingsd.com/20120405/exclusive-yahoos-chief-product-officer-blake-irving-resigns/ |url-status=live }}

Andrei Broder, who was VP of computational advertising and chief scientist of the Advertising Product Group, as well as Jianchang (JC) Mao, who headed advertising sciences, left the company.

On April 4, 2012, Yahoo announced a cut of 2,000 jobs or about 14 percent of 14,100 workers employed by Yahoo.

=Reorganization=

In an email memo sent to employees in April 2012, Scott Thompson re-iterated his view that customers should come first at Yahoo. He defined customers as both users and advertisers. He also re-organized the company. The reorganization took effect on May 1, 2012, and included operations in three major groups for Yahoo! {{En dash}} Consumer, Regions and Technology.

The Consumer group had three groups: Media, Connections, and Commerce. The customers of this group are the users of Yahoo!.

The Regions group operated three regions: Americas, APAC, and EMEA. The customers of this group are the advertisers of Yahoo!.

The Technology group included Core Platforms, and Central Technology. It provides technology and support to the other two major groups.

The Corporate group (Finance, Legal, and HR) remained unchanged and continued to support the new groups.{{cite web |url=http://allthingsd.com/20120410/its-official-yahoo-reorgs-itself-just-like-we-said-memo-time/ |title=It's Official: Yahoo Reorgs Itself Just Like We Said (Memo Time!) – Kara Swisher – News |publisher=AllThingsD |date=April 10, 2012 |access-date=2012-10-19 |archive-date=December 20, 2012 |archive-url=https://web.archive.org/web/20121220235004/http://allthingsd.com/20120410/its-official-yahoo-reorgs-itself-just-like-we-said-memo-time/ |url-status=live }}{{cite news | url=http://bits.blogs.nytimes.com/2012/04/10/yahoo-c-e-o-hints-at-a-strategy/ | work=The New York Times | first=Nicole | last=Perlroth | title=Yahoo C.E.O.
