More Info
Yahoo! Inc. (NASDAQ: YHOO) is an American internet corporation founded in Santa Clara,
California, and headquartered in Sunnyvale, California, United States. The company is perhaps
best known for its web portal, search engine (Yahoo! Search), Yahoo! Directory, Yahoo! Mail,
Yahoo! News, advertising, online mapping (Yahoo! Maps), video sharing (Yahoo! Video), and
social media websites and services. It is one of the largest websites in the United States.[2]

Yahoo! inclusive was founded by Jerry Yang and David Filo in January 1994 and was
incorporated on March 1, 1995. 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.[3] On September 6, 2011, Bartz was removed from her position at Yahoo! by chairman
Roy Bostock, over the phone; and CFO Tim Morse was named as Interim CEO of the

In January 1995, Jerry Yang and David Filo were electrical engineering graduate students at
Stanford University when they created a website named "David and Jerry's Guide to the World
Wide Web".[6] 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 April 1994,
"David and Jerry's Guide to the World Wide Web" was renamed "Yahoo!".[7][8] The
domain was created on January 18, 1995.[9] The word is an acronym for "Yet Another
Hierarchical Officious Oracle."[10] The term "hierarchical" described how the Yahoo! database
was arranged in directory layers. The term "oracle" was intended to mean "source of truth and
wisdom," and "officious" described the many office workers who would use the Yahoo! database
while surfing from work.[11] 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." "Yahoo" also stems from the name of a fictional being from Gulliver's Travels.

Yahoo! grew rapidly throughout the 1990s. Like many search engines and web directories,
Yahoo! diversified into a Web portal. 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 3 January 2000. However, after the dot-com bubble burst, it settled at a post-bubble low
of $4.05 on 26 September 2001.

In 2000, Yahoo! began using Google for search results. Over the next four years, it developed its
own search technologies, which it began using in 2004. Yahoo! also revamped its mail service to
compete with Google's Gmail in 2007. The company struggled through 2008, with several large

In February 2008, Microsoft Corporation made an unsolicited bid to acquire Yahoo! for USD
$44.6 billion. Yahoo! subsequently formally rejected the bid, claiming that it "substantially
undervalues" Yahoo! and was not in the interest of its shareholders. Three years later, Yahoo!
had a stock market capitalization of USD $22.24 billion.[12] Carol Bartz replaced cofounder Jerry
Yang in January 2009.[13] In September 2011 she was removed from her position at Yahoo! by
the company's chairman Roy Bostock (via phone call), and CFO Tim Morse was named as
Interim CEO of the company. Bartz expressed her desire to remain on the Board of

and sports information. The portal also gives users access to other Yahoo! services like Yahoo!
Mail, Yahoo! Maps, Yahoo! Finance, Yahoo! Groups and Yahoo! Messenger.

[edit] Storing personal information and tracking usage

Working with comScore, The New York Times found that Yahoo! is able to collect far more data
about webusers than its competitors from its websites 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.[16]

As of May 22, 2008, an article in Computer World states that Yahoo has a 2-petabyte, specially
built data warehouse, which it uses to analyze the behavior of its half-billion Web visitors per
month, processing 24 billion events a day. Yahoo claimed it is expected to grow in multiples of
10 petabytes by 2009 and that this database is the largest in the world.[17] In contrast the Internal
Revenue Services (IRS) database of all US taxpayers weighs in at only 150 TB.[17]

As of December 18, 2008, Yahoo! retains search requests for a period of 13 months. However, In
response to European Regulators, Yahoo scrambles the last eight digits of a users IP address after
three months, rendering them partially anonymous.[18]

360° as they intended to abandon it in early 2008 in favor of a "universal profile" that will be
similar to their Mash experimental system.[21]

Yahoo! also introduced its Internet search system, called oneSearch, developed for mobile
phones on March 20, 2007. The company's officials stated that in distinction from ordinary Web
searches, Yahoo!'s new service presents a list of actual information, which may include news
headlines, images from Yahoo!'s Flickr photos site, 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 a certain movie, along with user
ratings and news headlines regarding the movie. A zip code or city name is required for Yahoo!
oneSearch to start delivering local search results.

The results of a Web search are listed on a single page and are prioritized into categories. The list
of results is based on calculations that Yahoo! computers make on certain information the user is

Yahoo! launched its new Internet advertisement sales system on February 5, 2007, called

ads on search results pages. The system takes bids, ad quality, clickthrough rates and other

[edit] 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.[47]

The following services were in a column under "Sunset": Yahoo Picks, AltaVista, MyM,
AlltheWeb, Yahoo Bookmarks, Yahoo! Buzz,, and MyBlogLog. Under "Merge" was:
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.[48] Yahoo's Chief Product Officer and Executive Vice President Blake Irving
unofficially responded to the tweet implying that whoever sent him that particular slide is
fired.[citation needed]

The blog on released a post by Chris Yeh after the leak, detailing that "Sunset" in their
case doesn't necessarily mean they are closing down, and that other possibilities – including
Delicious leaving Yahoo (through sale or spinoff) – are still on the table and that Delicious will
not be closing down at this time; "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."[49] On April 27, 2011, an announcement said that
Delicious has been sold to Avos by Yahoo! [50]

Yahoo! Buzz was closed down on April 21, 2011 with no official announcement by Yahoo![51]

largest segment of it comes 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. With the search advertising system "Panama" Yahoo! aims to increase revenue generated
from search.[54]

Other forms of advertising which bring in revenue for Yahoo! include display and contextual
advertising.[citation needed]
[edit] Criticism
Main article: Criticism of Yahoo!

In 2000, Yahoo! was taken to court in France by parties seeking to prevent French citizens from
purchasing memorabilia relating to the Nazi Party.[55] In March 2004, Yahoo! launched a paid
inclusion program whereby commercial websites are guaranteed listings on the Yahoo! search
engine,[56] but Yahoo! discontinued the paid inclusion / search submit program at the end of
2009.[57] Yahoo! has also been criticized for providing ads via the Yahoo! ad network to
companies who display them through spyware and adware.[58][59]

Yahoo! as well as other search engines, have 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"[60] as a result of being identified by IP address by
Yahoo![61] The extent of Yahoo's foreknowledge of Shi's fate is disputed by Yahoo! General
Counsel and human rights organizations.[62] Human rights groups also accuse Yahoo! of aiding
authorities in the arrest of dissident Li Zhi. In September 2003, dissident Wang Xiaoning was
convicted of charges of "incitement to subvert state power" and sentenced to ten years in prison.
Yahoo! helped authorities to identify posts he had made in a Yahoo! group calling for an end to
single-party rule.[63] Both Xiaoning's wife and the World Organization for Human Rights[64] sued
Yahoo! under human rights laws on behalf of Wang and Shi.[65]

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.[66] On May 25,
2006, Yahoo!'s image search was criticized for bringing up sexually explicit images even when
SafeSearch was on.[67] Yahoo! is a 40% owner of Alibaba Group, which was previously a subject
of controversy for allowing the sale of shark-derived products. Nevertheless, the company
banned the sale of shark fin products on all its e-commerce platforms in 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
procedures[68] on obtaining private information pertaining to Yahoo!'s subscribers.[69]

After some concerns over censorship of private emails regarding a website affiliated with
Occupy Wall Street protests were raised,[70][71] Yahoo responded with an apology and explained
it as an accident.[72]

[edit] Yahoo subject of cyber attacks originating in China
Adobe and Yahoo appear to have been among the targets of cyber attacks originating in China
that prompted Google Inc. to threaten to leave the Asian nation in a surprise announcement on
January 12, 2010.[73]

[edit] Advertising Revenue

As of January, 2010, Yahoo held the world's largest market share in online display advertising.
JP Morgan put the company’s US market share for display ads at 17%, well ahead of No. 2
Microsoft at 11% and AOL at 7%.[75]

[edit] Yahoo! International
Yahoo! is known across the world with its multi-lingual interface. The site is available in over 20
languages, including English. The official directory for all of the Yahoo! International sites is

Each of the international sites are wholly owned by Yahoo!, with the exception of Yahoo! Japan
, in which it holds a 34.79% minority stake,[76] Yahoo!Xtra in New Zealand which Yahoo!7 have
51% of and 49% belongs to Telecom New Zealand and Yahoo!7 in Australia which is a 50-50
agreement between Yahoo! and the Seven Network. Historically, Yahoo! entered into joint
venture agreements with SoftBank for the major European sites (UK, France, Germany) and well
as Korea and Japan. In November 2005, Yahoo! purchased the minority interests that SoftBank
owned in Europe and Korea.

Yahoo! holds a 40% stake in Alibaba, which manages a web portal in China using the Yahoo!
brand name. Yahoo! in the USA does not have direct control over the operations of Alibaba,
which operates as a completely independent company.

In 2008, Darren Petterson, business development director for Yahoo! Europe confirmed that
Yahoo! was going to launch a Romanian version of their website by the end of the year,[77][78]
however, due to the financial crisis at that time, those plans were frozen.[79] In February 2010,
new reports appeared in the Romanian media claiming that the portal will finally launch by June
the same year, as some services like Yahoo! Mail and Yahoo! Mobile are already translated into
Romanian.[80][81] On 8 March 2011 Yahoo! launched its Romania local service.

[edit] Logos and themes
The first logo was used when the company was founded in 1995. It was red and had three icons
on each side.[82]
The logo used on the main page used to be red with a black outline and shadow, but
in May 2009, along with a new theme redesign, the logo was changed to purple with no outline
or shadow.

Sometimes, the logo is abbreviated with Y!.[83]

Themes and page designs are different on some international Yahoo! home pages, such as
Yahoo! Australia,[84] Yahoo! India,[85] etc
