Yahoo!

Yahoo! (, styled yahoo! in its logo) is an American web services provider. It is headquartered in Sunnyvale, California, and operated by the namesake company Yahoo! Inc., which is 90% owned by investment funds managed by Apollo Global Management and 10% by Verizon Communications.

It provides a web portal, search engine Yahoo Search, and related services, including My Yahoo!, Yahoo Mail, Yahoo News, Yahoo Finance, Yahoo Sports and its advertising platform, Yahoo! Native.

Yahoo was established by Jerry Yang and David Filo in January 1994 and was one of the pioneers of the early Internet era in the 1990s. However, its use declined in the late 2000s as some of its services were discontinued, and it lost market share to Facebook and Google.

Founding


In January 1994, Jerry Yang and David 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 human-edited web directory, 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!" and became known as the Yahoo Directory. The "yahoo.com" domain was registered 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 Travels.

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. Yahoo soon became the first popular online directory and search engine on the World Wide Web.

Expansion
Yahoo grew rapidly throughout the 1990s. Yahoo became a public company via an initial public offering in April 1996 and its stock price rose 600% within two years. Like many search engines and web directories, Yahoo added a web portal, putting it in competition with services including Excite, Lycos, and America Online. By 1998, Yahoo was the most popular starting point for web users, and the human-edited Yahoo Directory the most popular search engine, receiving 95 million page views per day, triple that of rival Excite. It also made many high-profile acquisitions. Yahoo began offering free e-mail from October 1997 after the acquisition of RocketMail, which was then renamed to Yahoo Mail. In 1998, Yahoo replaced AltaVista as the crawler-based search engine underlying the Directory with Inktomi. Yahoo's two biggest acquisitions were made in 1999: Geocities for $3.6 billion and Broadcast.com for $5.7 billion.

Its stock price skyrocketed during the dot-com bubble, closing at an all-time high of $118.75/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 began using Google for search in June 2000. Over the next four years, it developed its own search technologies, which it began using in 2004 partly using technology from its $280 million acquisition of Inktomi in 2002. In response to Google's Gmail, Yahoo began to offer unlimited email storage in 2007. In 2008, the company laid off hundreds of people as it struggled from competition.

In February 2008, Microsoft made an unsolicited bid to acquire Yahoo for $44.6 billion. Yahoo rejected the bid, claiming that it "substantially undervalues" the company and was not in the interest of its shareholders. Although Microsoft increased its bid to $47 billion, Yahoo insisted on another 10%+ increase to the offer and Microsoft cancelled the offer in May 2008.

Carol Bartz, who had no previous experience in Internet advertising, replaced Yang as CEO in January 2009. In September 2011, after failing to meet targets, she was fired by chairman Roy J. Bostock; CFO Tim Morse was named as Interim CEO of the company.

In April 2012, after the appointment of Scott Thompson as CEO, several key executives resigned, including chief product officer Blake Irving. On April 4, 2012, Yahoo announced 2,000 layoffs, or about 14% of its 14,100 workers by the end of year, expected to save around $375 million annually. 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.

On May 13, 2012, Thompson was fired and was replaced on an interim basis by Ross Levinsohn, recently appointed head of Yahoo's new Media group. Several associates of Third Point Management, including Daniel S. Loeb were nominated to the board of directors. Thompson's total compensation for his 130-day tenure with Yahoo was at least $7.3 million.

On July 15, 2012, Marissa Mayer was appointed president and CEO of Yahoo, effective July 17, 2012.

In June 2013, Yahoo acquired blogging site Tumblr for $1.1 billion in cash, with Tumblr's CEO and founder David Karp continuing to run the site. In July 2013, Yahoo announced plans to open an office in San Francisco.

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, during the month, more people in the U.S. visited Yahoo websites than Google; the first time that Yahoo outperformed Google since 2011. The data did not count mobile usage, nor Tumblr.

Mayer also hired Katie Couric to be the anchor of a new online news operation and started an online food magazine. However, by January 2014, doubts about Mayer's progress emerged when Mayer fired her own first major hire, Henrique de Castro.

On December 12, 2014, Yahoo acquired video advertising provider BrightRoll for $583 million.

On November 21, 2014, Yahoo acquired Cooliris.

In August 2023, it was announced Yahoo had acquired the San Francisco-headquartered social investing platform, Commonstock.

In April 2024, it was announced Yahoo had acquired the AI-driven news aggregator app, Artifact.

Decline, security breaches, and sale
By December 2015, Mayer was criticized as performance declined. Mayer was ranked as the least likable CEO in tech.

On February 2, 2016, Mayer announced layoffs amounting to 15% of the Yahoo! workforce.

On July 25, 2016, Verizon Communications announced the acquisition of Yahoo's core Internet business for $4.83 billion. The deal excluded Yahoo's 15% stake in Alibaba Group and 35.5% stake in Yahoo Japan.

On February 21, 2017, as a result of the Yahoo data breaches, Verizon lowered its purchase price for Yahoo by $350 million and reached an agreement to share liabilities regarding the data breaches.

On June 13, 2017, Verizon completed the acquisition of Yahoo and Marissa Mayer resigned.

Yahoo, AOL, and HuffPost were to continue operating under their own names, under the umbrella of a new company, Oath Inc., later called Verizon Media.

The parts of the original Yahoo! Inc. which were not purchased by Verizon Communications were renamed Altaba, which was later liquidated, making a final distribution in October 2020.

In September 2021, investment funds managed by Apollo Global Management acquired 90% of Yahoo.

In November 2021, Yahoo announced that it was ending operations in mainland China due to the increasingly challenging business and legal environment. Previously, the company discontinued China Yahoo! Mail on August 20, 2013.

In 2023, Yahoo announced that it would cut 20% of its workforce. The move followed mass layoffs from other tech giants including Google, Microsoft, Twitter, Inc, Meta, and Amazon. The company is set to lay off roughly 1,000 staff members of their 8,600 workers.
