History and growth
In January 1994, Yang and Filo were electrical engineering graduate students at Stanford University when they created a website named "Jerry's guide to the World Wide Web".9 David and Jerry's Guide to the World Wide Web was a directory of other websites, organized in a hierarchy, as opposed to a searchable index of pages. In March 1994, "David and Jerry's Guide to the World Wide Web" was renamed "Yahoo!"1011 The "yahoo.com" domain was created on January 18, 1995.12
The word "yahoo" is an acronym for "Yet Another Hierarchical Officious Oracle".13 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.14 However, 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." Filo's college girlfriend often referred to Filo as a "yahoo." This meaning derives from the name of a race of fictional beings from Gulliver's Travels.
Yahoo grew rapidly throughout the 1990s. Like many search engines and Web directories, Yahoo added a web portal. As of 1998, Yahoo! was the most popular starting point for web users.15 It also made many high-profile acquisitions. Its stock price skyrocketed during the dot-com bubble, Yahoo stocks closing at an all-time high of $118.75 a share on January 3, 2000. However, after the dot-com bubble burst, it reached a post-bubble low of $8.11 on September 26, 2001.16
In 2000, Yahoo began using Google for search. Over the next four years, it developed its own search technologies, which it began using in 2004. In response to Google's Gmail, Yahoo began to offer unlimited email storage in 2007. The company struggled through 2008, with several large layoffs.citation needed
In February 2008, Microsoft Corporation made an unsolicited bid to acquire Yahoo for US$44.6 billion. Yahoo formally rejected the bid, claiming that it "substantially undervalues" the company and was not in the interest of its shareholders. Three years later, Yahoo had a market capitalization of US$22.24 billion.17 Carol Bartz replaced Yang as CEO in January 2009.18 In September 2011, she was removed from her position at Yahoo by the company's chairman Roy Bostock, and CFO Tim Morse was named as Interim CEO of the company.
In early 2012, after the appointment of Scott Thompson as CEO, rumors began to spread about looming layoffs. Several key executives, such as Chief Product Officer Blake Irving left.19 On April 4, 2012, Yahoo announced a cut of 2,000 jobs or about 14 percent of its 14,100 workers. The cut is expected to save around US$375 million annually after the layoffs are completed at end of 2012.20 In an email sent to employees in April 2012, Thompson reiterated his view that customers should come first at Yahoo He also completely reorganized the company.21
On May 13, 2012, Yahoo issued a press release stating that Thompson was no longer with the company, and would immediately be replaced on an interim basis by Ross Levinsohn, recently appointed head of Yahoo's new Media group.212223 Thompson's total compensation for his 130-day tenure with Yahoo was at least $7.3 million.24
On July 16, 2012, Marissa Mayer was appointed President and CEO of Yahoo, effective the following day.
On May 19, 2013 the Yahoo board approved a US$1.1 billion purchase of blogging site Tumblr, and the company's CEO and founder David Karp will remain a large shareholder. The announcement reportedly signifies a changing trend in the technology industry, as large corporations like Yahoo, Facebook, and Google acquire start-up Internet companies that generate low amounts of revenue as a way in which to connect with sizeable, fast-growing online communities. The Wall Street Journal stated that the purchase of Tumblr would satisfy the company's need for "a thriving social-networking and communications hub."2526 On May 20, the company announced the acquisition of Tumblr officially.27 The company also announced plans to open a San Francisco office in July 2013.28
On August 2, 2013, Yahoo Inc. announced the acquisition of social Web browser concern RockMelt. With the acquisition, the RockMelt team, including the concern's CEO Eric Vishria and CTO Tim Howes, will be the part of Yahoo team. As a result, all the RockMelt applications and existing Web services were terminated on August 31.29
Data collated by comScore during July 2013 revealed that more people in the U.S. visited Yahoo Web sites during the month in comparison to Google Web sites; the occasion was the first time that Yahoo outperformed Google since 2011. The data did not incorporate visit statistics for the Yahoo-owned Tumblr site or mobile phone usage.30

Storing personal information and tracking usage
|This section's factual accuracy may be compromised due to out-of-date information. (June 2012)|
Working with comScore, The New York Times found that Yahoo was able to collect far more data about users than its competitors from its Web sites and advertising network. By one measure, on average Yahoo had the potential in December 2007 to build a profile of 2,500 records per month about each of its visitors.31 Yahoo retains search requests for a period of 13 months. However, in response to European regulators, Yahoo obfuscates the IP address of users after three months by deleting its last eight bits.32
According to a 2008 article in Computerworld, Yahoo has a 2-petabyte, specially built data warehouse that it uses to analyze the behavior of its half-billion Web visitors per month, processing 24 billion daily events.34 In contrast, the United States Internal Revenue Service (IRS) database of all United States taxpayers weighs in at only 150 terabytes.34

Yahoo Photos was closed on September 20, 2007, in favor of Flickr. On October 16, 2007, Yahoo announced that it would discontinue Yahoo 360°, including bug repairs; the company explained that in 2008 it would instead establish a "universal profile" similar to the Yahoo Mash experimental system.37
Yahoo partners with numerous content providers in products such as Yahoo Sports, Yahoo Finance, Yahoo Music, Yahoo Movies, Yahoo Weather, Yahoo News, Yahoo Answers and Yahoo Games to provide news and related content. Yahoo provides a personalization service, My Yahoo, which enables users to combine their favorite Yahoo features, content feeds and information onto a single page.

The results include news headlines, images from Flickr, business listings, local weather and links to other sites. Instead of showing only, for example, popular movies or some critical reviews, OneSearch lists local theaters that at the moment are playing the movie, along with user ratings and news headlines regarding the movie. A zip code or city name is required for OneSearch to start delivering local search results.
The results of a Web search are listed on a single page and are prioritized into categories.39

Through Panama, Yahoo aims to provide more relevant search results to users, a better overall experience, and to increase monetization.44
On April 7, 2008, Yahoo announced APT from Yahoo, which was originally called AMP from Yahoo,45 an online advertising management platform.46 The platform simplifies advertising sales by unifying buyer and seller markets. The service was launched in September 2008.47
In September 2011, Yahoo formed an ad selling strategic partnership with 2 of its top competitors, AOL and Microsoft.48 But by 2013 this was found to be underperforming in market share and revenue, as Microsoft simply skimmed off four percent of the search market from Yahoo, without growing their combined share.49
Yahoo Next is an incubation ground for future Yahoo technologies currently undergoing testing. It contains forums for Yahoo users to give feedback to assist in the development of these future Yahoo technologies.50
Yahoo Search BOSS is a service that allows developers to build search applications based on Yahoo's search technology.51 Early Partners in the program include Hakia, Me.dium, Delver, Daylife and Yebol.52
In early 2011, the program switched to a paid model using a cost-per-query model from $0.40 to $0.75 CPM (cost per 1000 BOSS queries). The price, as Yahoo explained, depends on whether the query is of web, image, news or other information.53

Yahoo SearchMonkey (often misspelled Search Monkey) was a Yahoo service which allowed developers and site owners to use structured data to make Yahoo Search results more useful and visually appealing, and drive more relevant traffic to their sites. The service was shut down in October 2010 along with other Yahoo services as part of the Microsoft and Yahoo search deal. The name SearchMonkey is an homage to Greasemonkey. Officially the product name has no space and two capital letters.
Yahoo SearchMonkey was selected as one of the top 10 Semantic Web Products of 2008.58
Geocities was a popular web hosting service founded in 1995 and was one of the first services to offer web pages to the public. At one point it was the third-most-browsed site on the World Wide Web.59 Yahoo purchased GeoCities in 1999 and ten years later the web host was closed, deleting some seven million web pages.60 A great deal of information was lost but many of those sites and pages were mirrored at the Internet Archive,61 OOcities.com, and other such databases.62

Twitter slide leak on upcoming changes to Yahoo
On December 15, 2010, one day after Yahoo announced layoffs of 4% of its workers across their portfolio, MyBlogLog founder Eric Marcoullier posted a slide from a Yahoo employee on Twitter. The slide was visible during an employee-only strategy webcast indicating changes in Yahoo's offerings.74
The following services were in a column under "Sunset": Yahoo Picks, AltaVista, MyM, AlltheWeb, Yahoo Bookmarks, Yahoo Buzz, del.icio.us, and MyBlogLog. Under the "Merge" column were: Upcoming, FoxyTunes, Yahoo Events, Yahoo People Search, Sideline, and FireEagle.
11 other properties were listed that Yahoo was interested in developing into feature sites within the portal to take the place of the "Sunset" and "Merge" vacancies, including the prior feature services (before the new Yahoo Mail was launched), were Yahoo Address Book, Calendar, and Notepad.75 Despite Notepad being listed as a feature service instead of sunset or merge in 2010, Yahoo has since taken steps to de-emphasize Notepad. For example, in January 2013, Notepad was no longer linked within the new Yahoo mail service, although it continued to be linked in the older Classic version. Also, starting in mid- to late January 2013, Notepad was no longer searchable.citation needed
The blog on the del.icio.us website released a post by Chris Yeh after the slide was leaked in which Yeh stated that "Sunset" doesn't necessarily mean that Yahoo is closing down the site. Yeh further explained that other possibilities—including del.icio.us leaving Yahoo (through sale or spinoff)—were still being considered: "We can only imagine how upsetting the news coverage over the past 24 hours has been to many of you. Speaking for our team, we were very disappointed by the way that this appeared in the press."76 On April 27, 2011, Yahoo's sale of del.icio.us to Avos was announced.77

About 88% of revenues for the fiscal year 2009 came from marketing services.citation needed The largest segment of it was from search advertising, where advertisers bid for search terms to display their ads on the search results; on average Yahoo makes 2.5 cents to 3 cents from each search.
Other forms of advertising that bring in revenue for Yahoo include displaycitation needed and contextual advertising, with the latter providing the basis for the "Keystone" initiative (developed by Yahoo to develop an "ad selection technology for direct and online marketers to place non-guaranteed advertisements on publisher sites.")80

Yahoo, as well as other search engines, cooperated with the Chinese government in censoring search results. In April 2005, dissident Shi Tao was sentenced to 10 years in prison for "providing state secrets to foreign entities"89 as a result of being identified by IP address by Yahoo90 The extent of Yahoo's foreknowledge of Shi's fate was disputed by the company's General Counsel and human rights organizations.91 Human rights groups also accuse Yahoo of aiding authorities in the arrest of dissidents Li Zhi and Jiang Lijun.
In September 2003, dissident Wang Xiaoning was convicted of charges of "incitement to subvert state power" and was sentenced to ten years in prison. Yahoo Hong Kong connected Wang's group to a specific Yahoo e-mail address.92 Both Xiaoning's wife and the World Organization for Human Rights93 sued Yahoo under human rights laws on behalf of Wang and Shi.94
As a result of media scrutiny relating to Internet child predators and a lack of significant ad revenues, Yahoo's "user created" chatrooms were closed down in June 2005.95 On May 25, 2006, Yahoo's image search was criticized for bringing up sexually explicit images even when SafeSearch was active.96 Yahoo was a 40% owner of Alibaba Group (now 24%),97 which was a subject of controversy for allowing the sale of shark-derived products. The company banned the sale of shark fin products on all its e-commerce platforms effective January 1, 2009. On November 30, 2009, Yahoo was criticized by the Electronic Frontier Foundation for sending a DMCA notice to whistle-blower website "Cryptome" for publicly posting details, prices, and procedures98 on obtaining private information pertaining to Yahoo's subscribers.99

Logos and themes
The first logo appeared when the company was founded in 1994—it was red with three icons on each side.123 The logo used on the Yahoo home page formerly consisted of the color red with a black outline and shadow; however, in May 2009, together with a theme redesign, the logo was changed to purple without an outline or shadow. This change also applied to several international Yahoo home pages. In some countries, most notably Yahoo!7 (of Australia), the logo remains red.124 On occasion the logo is abbreviated: "Y!".125
On August 7, 2013, at around midnight EDT, Yahoo announced that the final version of the new logo would be revealed on September 5, 2013 at 4:00 a.m. UTC. In the period leading up to the unveiling of the new logo, the "30 Days of Change" campaign was introduced, whereby a variation of the logo was published every day for the 30 days following the announcement.126127 The new logo was eventually launched with an accompanying video that showed its digital construction, and Mayer published a personalized description of the design process on her Tumblr page.128 Mayer explains:
So, one weekend this summer, I rolled up my sleeves and dove into the trenches with our logo design team ... We spent the majority of Saturday and Sunday designing the logo from start to finish, and we had a ton of fun weighing every minute detail. We knew we wanted a logo that reflected Yahoo - whimsical, yet sophisticated. Modern and fresh, with a nod to our history. Having a human touch, personal. Proud.129
On September 19, 2013, Yahoo! launched a new version of the "My Yahoo" personalized homepage. The redesign allows users to tailor a homepage with widgets that access features such as email accounts, calendars, Flickr and other Yahoo content, and Internet content. Users can also select "theme packs" that represent artists such as Polly Apfelbaum and Alec Monopoly, and bands such as Empire of the Sun.130 Mayer then explained at a conference in late September 2013 that the logo change was the result of feedback from both external parties and employees.131
