Yahoo! is a web services provider that is wholly owned by Verizon
Communications through Oath Inc., and headquartered in
Sunnyvale, California. The original
Yahoo! company was founded by
Jerry Yang and
David Filo in January 1994 and was incorporated on
March 2, 1995. Yahoo was one of the pioneers of the early
Internet era in the 1990s.
It was globally known for its Web portal, search engine
and related services, including
Yahoo! Mail, Yahoo!
Yahoo! Answers, advertising,
online mapping, video sharing, fantasy sports, and its social media
website. At its height it was one of the most popular sites in the
United States. According to third-party web analytics providers,
Alexa and SimilarWeb,
Yahoo! was the highest-read news and media
website, with over 7 billion views per month, being the sixth most
visited website globally in 2016. According to news
sources, roughly 700 million people visited Yahoo websites every
month. Yahoo itself claimed it attracted "more than half a
billion consumers every month in more than 30 languages".
Once the most popular website in the U.S., Yahoo slowly declined,
starting in the late 2000s, and in 2017
acquired most of Yahoo's Internet business for $4.48 billion,
excluding its stakes in
Alibaba Group and
Yahoo! Japan, which were
transferred to Yahoo's successor company Altaba.

Jerry Yang and David Filo, the founders of Yahoo
In January 1994, Yang and Filo were electrical engineering graduate
students at Stanford University, when they created a website named
"Jerry and David's guide to the World Wide Web". The site was
a directory of other websites, organized in a hierarchy, as opposed to
a searchable index of pages. In March 1994, "Jerry and David's Guide
to the World Wide Web" was renamed "Yahoo!". The human-edited
Yahoo! Directory, provided for users to surf through the Internet,
became their first product and the company's original purpose.
The "yahoo.com" domain was created on January 18, 1995.
The word "yahoo" is a backronym for "Yet Another Hierarchically
Organized Oracle" or "Yet Another Hierarchical Officious
Oracle". 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. 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." This meaning
derives from the Yahoo race of fictional beings from Gulliver's
Yahoo grew rapidly throughout the 1990s. Like many search engines and
web directories, Yahoo added a web portal. By 1998, Yahoo was the most
popular starting point for web users, and the human-edited Yahoo
Directory the most popular search engine. 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.
Yahoo headquarters in 2001
Yahoo began using Google for search in 2000. 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.
In February 2008,
Microsoft Corporation made an unsolicited bid to
acquire Yahoo for $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 $22.24 billion.
Carol Bartz replaced Yang
as CEO in January 2009. 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 left,
including Chief Product Officer Blake Irving. On April 4, 2012,
Yahoo announced a cut of 2,000 jobs, or about 14 percent of its 14,100
workers. The cut was expected to save around $375 million annually
after the layoffs were completed at end of 2012. In an email sent
to employees in April 2012, Thompson reiterated his view that
customers should come first at Yahoo. He also completely reorganized
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. Thompson's total compensation for his
130-day tenure with Yahoo was at least $7.3 million.
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 $1.1 billion purchase of
blogging site Tumblr. Tumblr's CEO and founder
David Karp would remain
a large shareholder. The announcement reportedly signified a changing
trend in the technology industry, as large corporations like Yahoo,
Facebook, and Google acquired start-up Internet companies that
generated 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 Yahoo's need for "a
thriving social-networking and communications hub." On May 20,
the company announced the acquisition of
Tumblr officially. The
company also announced plans to open a San Francisco office in July
On August 2, 2013, Yahoo acquired Rockmelt; its staff was retained,
but all of its existing products were terminated.
Data collated by comScore during July 2013 revealed that more people
in the U.S. visited Yahoo websites during the month than Google; the
occasion was the first time that Yahoo outperformed Google since
2011. The data did not count mobile usage, nor Tumblr.
In November 2014,
Yahoo! announced that it would acquire the video
BrightRoll for $640 million.

however, the share price peaked at about $35 in November 2013. It

on news that the board of directors was meeting to decide on the
future of Mayer, whether to sell the struggling Internet business,
and whether to continue with the spinoff of its stake in China's
Alibaba e-commerce site. Not all had gone well during Mayer's
tenure, including the $1.1 billion acquisition of
Tumblr that had yet
to prove beneficial and the forays into original video content that
led to a $42 million write-down. Sydney Finkelstein, a professor at
Dartmouth College's Tuck School of Business, told The Washington Post
that sometimes, "the single best thing you can do ... is sell the
company." The closing price of

Verizon Communications announced that it had agreed
to purchase Yahoo's core Internet business for $4.83
billion. Following the conclusion of the purchase, these
assets will be merged with
AOL to form a new entity known as Oath
Inc.; Yahoo, AOL, and Huffington Post will continue to operate under
their own names, under the
Oath Inc. umbrella. The deal excludes
Yahoo's 15% stake in
Alibaba Group and 35.5% stake in
following the completion of the acquisition, these assets will be
retained under the name Altaba, with a new executive team.
On September 22, 2016, Yahoo disclosed a data breach that occurred in
late 2014, in which information associated with at least 500 million
user accounts, one of the largest breaches reported to date.
The United States have indicted four men, including two employees of
Federal Security Service
Federal Security Service (FSB), for their involvement in the
hack. On December 14, 2016, the company revealed that another
separate data breach had occurred in 2014, with hackers obtaining
sensitive account information, including security questions, to at
least one billion accounts. The company stated that hackers had
utilized stolen internal software to forge HTTP cookies.
In response to these breaches,
Bloomberg News reported that Verizon
was attempting to re-negotiate the deal to reduce the purchase price
by $250 million, causing a 2% increase in Yahoo stock prices.
On February 21, 2017,
Verizon agreed to lower its purchase price for
Yahoo! by $350 million, and share liabilities regarding the
investigation into the data breaches.
On June 8, 2017, Yahoo shareholders approved the company's sale of
some of its Internet assets to
Verizon for $4.48 billion. The deal
officially closed on June 13, 2017.
In a press release from October 3, 2017, Oath Inc., a subsidiary of
Verizon, stated that all Yahoo user accounts, some 3 billion, were
affected by the August 2013 theft.

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" as a result of being identified by IP
address by Yahoo. Human rights organizations and the company's
general counsel disputed the extent of Yahoo's foreknowledge of Shi's
fate. Human rights groups also accuse Yahoo of aiding authorities
in the arrest of dissidents Li Zhi and Jiang Lijun. In April 2017,
Yahoo was sued for failing to uphold settlement agreements in this
case. Yahoo pledged to give support to the families of those arrested
and create a relief fund for those persecuted for expressing their

Allegations of sexism against men
Scott Ard, a prominent editorial director, fired from Yahoo in 2015
has filed a lawsuit accusing Mayer of leading a sexist campaign to
purge male employees. Ard, a male employee, stated "Mayer encouraged
and fostered the use of (an employee performance-rating system) to
accommodate management's subjective biases and personal opinions, to
the detriment of Yahoo's male employees". In the suit Ard claimed
prior to his firing, he had received "fully satisfactory" performance
reviews since starting at the company in 2011 as head of editorial
programming for Yahoo's home page, however, he was relieved of his
role that was given to a woman who had been recently hired by Megan
Lieberman, the editor-in-chief of Yahoo News.
The lawsuit states: "Liberman stated that she was terminating (Ard)
because she had not received a requested breakdown of (his) duties.
(Ard) had already provided that very information as requested,
however, and reminded Liberman that he had done so. Liberman's excuse
for terminating (Ard) was a pretext."
A second sexual discrimination lawsuit was filed separately by Gregory
Anderson, who was fired in 2014, alleging the company's performance
management system was arbitrary and unfair, making it the second
sexism lawsuit Yahoo and Mayer has faced in 2016.

the country, with its previous domain saying in Korean, "Starting from
December 31, 2012,
Yahoo! Korea has ended. You can go to the original
Yahoo! for more Yahoo's information." Sooner did that message also
disappear, leaving with just an abandoned, empty search bar powered by

Logos and themes
Wordmark used from 1995 to 2013 (shown: purple variant used from
2009); red version still used by
Y! moniker (2009–2013)
Yahoo! sign with address at its headquarters
The first logo appeared when the company was founded in 1994—it was
red with three icons on each side. 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,
Yahoo!7 (of Australia), the logo remained red until
2014. On occasion the logo is abbreviated: "Y!"
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. 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. 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.
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. Mayer
then explained at a conference in late September 2013 that the logo
change was the result of feedback from both external parties and
