Yahoo

1994

GeoCities was a popular web hosting service founded in 1994. At the point Yahoo! purchased it in January 1999, it was reportedly the third most-browsed site on the World Wide Web. Despite its popularity, it had still not become profitable by late 1998.

January 1994

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.

January 1994

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 2010s as some of its services were discontinued, and it lost market share to Facebook and Google.

1995

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.

April 1996

Throughout the 1990s, Yahoo grew rapidly and 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, pitching itself against 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 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.

1998

Yahoo's corporate direction was heavily influenced by a series of leadership changes and missed opportunities. The company had two failed attempts to acquire Google; in 1998, Larry Page and Sergey Brin approached Yahoo to sell their nascent search engine for $1 million, but Yahoo declined the offer. In 2002, CEO Terry Semel entered into negotiations to purchase Google for a reported $5 billion. After weeks of negotiation, Yahoo's final offer was $3 billion, a figure that Google's leadership rejected. The failure to acquire Google in this second instance is widely considered one of the largest strategic errors in corporate history.

2000

In 2000 and 2001, Wang, who was an engineer by profession, posted electronic journals in a Yahoo! group calling for democratic reform and an end to single-party rule. He was arrested in September 2002 after Yahoo! assisted Chinese authorities by providing information. In September 2003, Wang was convicted of charges of "incitement to subvert state power" and sentenced to ten years in prison.

January 03, 2000

Its stock price skyrocketed during the dot-com bubble, closing at an all-time high of $118.75 per share on January 3, 2000 and bottomed out at $8.11 on September 26, 2001.

June 2000

Throughout the 2000s and 2010s, Yahoo continuously adapted its products and services to keep pace with shifting internet trends. Yahoo began using Google for search in June 2000, but over the next four years, it developed its own search technologies. It began using these in 2004, partly incorporating 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, though it struggled with competition and laid off hundreds of people in 2008.

September 11, 2001

On September 11, 2001, Yahoo announced its partnership with FIFA for the 2002 FIFA World Cup and 2006 FIFA World Cup tournaments. It was one of FIFA's 15 partners at the tournaments. The deal included co-branding the organization's websites.

December 2003

In February 2006, Reporters Without Borders released Chinese court documents stating that Yahoo! aided Chinese authorities in the case of dissident Li Zhi. In December 2003, Li Zhi was sentenced to 8 years imprisonment for "inciting subversion".

February 22, 2004

In July 2007, evidence surfaced detailing the warrant which the Chinese authorities sent to Yahoo! officials, highlighting "State Secrets" as the charge against Shi Tao. The warrant requests to provide "all login times, corresponding IP addresses, and relevant email content from February 22, 2004, to present." for email ID "huoyan1989" Analyst reports and human rights organizations have said that this evidence directly contradicts Yahoo!'s testimony before the U.S. Congress in February 2006.

March 2004

Yahoo's decline was punctuated by a series of strategic missteps and severe security incidents. In March 2004, the company launched a paid inclusion program that guaranteed commercial websites listings on the Yahoo! search engine in exchange for payment. While initially lucrative, the scheme proved highly unpopular with marketers who resisted the fees, and the public, who disliked that paid listings were indistinguishable from organic search results. By October 2006, Yahoo eased the program, ceasing to guarantee commercial listings and instead using paid inclusion only to crawl customer sites more frequently and provide search statistics. Security vulnerabilities also plagued the company; in January 2014, a large-scale malware attack dating back to December 30, 2013, was discovered by Fox IT in the Netherlands. Targeting Java, the attack delivered malware to 300,000 Yahoo! users per hour before it was stopped, heavily affecting users in Romania, France, and the UK. Yahoo! faced heavy criticism for failing to provide public guidance on the number of affected users or advice on remediation. These security issues culminated in the massive Yahoo data breaches, which later directly impacted the company's financial valuation.

April 2005

In September 2005, Reporters Without Borders reported that in April 2005, Shi Tao, a journalist working for a Chinese newspaper, was sentenced to 10 years in prison by the Changsha Intermediate People's Court of Hunan Province, China (First trial case no. 29), for "providing state secrets to foreign entities". The "secrets" were a brief list of censorship orders he sent from a Yahoo! Mail account to the Asia Democracy Forum before the anniversary of the 1989 Tiananmen Square protests and massacre.

June 2005

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. Yahoo! News' message board section was closed December 19, 2006, due to the trolling phenomenon. In addition, in mid-October 2008, Yahoo! deleted all information in millions of user profiles with no advance notice and little explanation.

February 2006

In February 2006, Yahoo! General Counsel submitted a statement to the U.S. Congress in which Yahoo! denied knowing the true nature of the case against Shi Tao. In April 2006, Yahoo! Holdings (Hong Kong) was investigated by Hong Kong's Privacy Commissioner for Personal Data.

May 25, 2006

On May 25, 2006, a teacher who was intending to use the service with a class to search for "www", discovered that Yahoo!'s image search brought up sexually explicit images even when SafeSearch was on. Yahoo!'s response to this was, "Yahoo! is aware of this issue and is working to resolve it as quickly as possible".

June 2006

On 2 June 2006, the union representing journalists in the UK and Ireland (NUJ) called on its 40,000 members to boycott all Yahoo! Inc. products and services to protest the Internet company's reported actions in China.

April 18, 2007

On April 18, 2007, Xiaoning's wife Yu Ling sued Yahoo! under human rights laws in federal court in San Francisco, California, United States. Wang Xiaoning is named as a plaintiff in the Yahoo! suit, which was filed with help from the World Organization for Human Rights USA. "Yahoo! is guilty of 'an act of corporate irresponsibility,' said Morton Sklar, executive director of the group. "Yahoo! had reason to know that if they provided China with identification information that those individuals would be arrested."

August 28, 2007

On August 28, 2007, the World Organization for Human Rights sued Yahoo! for allegedly passing information (email and IP address) with the Chinese government that caused the arrests of writers and dissidents. The lawsuit was filed in San Francisco for journalists, Shi Tao, and Wang Xiaoning. Yahoo! stated that it supported privacy and free expression for it worked with other technology companies to solve human rights concerns.

November 06, 2007

On November 6, 2007, the US congressional panel criticised Yahoo! for not giving full details to the House Foreign Affairs Committee the previous year, stating it had been "at best inexcusably negligent" and at worst "deceptive".

February 2008

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.

2009

Yahoo Inc. previously owned a 14.95% stake in Alibaba, which had been criticized for facilitating the sale of shark-derived products. After investing in Alibaba, Yahoo! executives were asked about this issue, and responded: "We know the sale of shark products is both legal in Asia and a centuries-old tradition. This issue is largely a cultural-practices one." Alibaba would later ban the sale of shark fins on its platform in 2009.

January 2009

The company subsequently cycled through several chief executives. Carol Bartz, formerly the CEO of Autodesk, replaced Yang as CEO in January 2009. After failing to meet performance targets, she was fired by chairman Roy J. Bostock in September 2011, and CFO Tim Morse was named as interim CEO. Following the appointment of Scott Thompson as CEO in April 2012, several key executives, including chief product officer Blake Irving, resigned. On April 4, 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 that April, Thompson reiterated his view that customers should come first and completely reorganized the company.

September 2009

Ten years later Yahoo! closed Geocities, deleting millions of web pages in the process. In September 2009, a month before it was closed, GeoCities received 10,477,049 unique visitors.

November 30, 2009

On November 30, 2009, Yahoo was criticized by the Electronic Frontier Foundation for sending a DMCA notice to whistleblower website "Cryptome" for publicly posting details, prices, and procedures on obtaining private information pertaining to Yahoo's subscribers.

August 2010

The company's product strategy frequently experienced turbulence. In August 2010, Yahoo! Groups rolled out a major software change that was denounced by a vast majority of users, prompting vice president Jim Stoneham to announce on September 29 that the site would roll back the changes based on member feedback. Despite these setbacks, Yahoo achieved a brief traffic milestone in July 2013 when comScore data revealed that more people in the U.S. visited Yahoo websites than Google—the first time Yahoo had outperformed Google since 2011. This data did not count mobile usage or Tumblr, the blogging platform Yahoo had acquired in June 2013 for $1.1 billion in cash. Under the deal, Tumblr's CEO and founder David Karp continued to run the site. That same month, Yahoo announced plans to open a new office in San Francisco, and on August 2, it acquired Rockmelt, retaining its staff but terminating all of its existing products.

2011

Mayer's human resources policies and performance-rating systems drew severe legal challenges. In October 2016, Scott Ard, a prominent editorial director who had been fired in 2015, filed a lawsuit accusing Mayer of leading a sexist campaign to purge male employees. Ard, who had received "fully satisfactory" reviews since starting in 2011, alleged that Mayer encouraged the use of an employee performance-rating system to accommodate management's subjective biases against men. He claimed his role was eliminated as a pretext and given to a woman recently hired by editor-in-chief Megan Lieberman. As the lawsuit noted, Lieberman stated she was terminating Ard because she had not received a requested breakdown of his duties, despite him having already provided that exact information. A second sexual discrimination lawsuit was filed separately by Gregory Anderson, who had been fired in 2014, echoing claims that the performance management system was arbitrary and unfair. A California magistrate dismissed all the plaintiffs' claims except one: that Ard was passed over for promotion to editor-in-chief in favour of a woman prior to his dismissal. The judge found that "Anderson has not provided any evidence that his termination had anything to do with his gender".

May 13, 2012

Thompson's tenure proved brief; he was fired on May 13, 2012, and replaced on an interim basis by Ross Levinsohn, who himself had recently been appointed head of Yahoo's new Media group. Several associates of Third Point Management, including Daniel S. Loeb, were also 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. Under Mayer's leadership, doubts about the company's turnaround emerged by January 2014 when she fired her own first major hire, Henrique de Castro.

2013

Yahoo announced television video partnerships in 2013 with Condé Nast, WWE, ABC NEWS, and CNBC. Yahoo entered into a 10-year collaboration in 2014, as a founding partner of Levi's Stadium, home of the San Francisco 49ers.

May 2013

Marissa Mayer's tenure as CEO became increasingly defined by internal controversy and deteriorating performance metrics. By December 2015, as the company's performance declined, Mayer faced intense scrutiny from the board regarding the future of Yahoo's core business. She was subsequently ranked as the least likable CEO in the tech industry. Product overhauls also alienated users; when Flickr unveiled a redesigned layout in May 2013—featuring one terabyte of free storage and a dynamically re-sized photo grid—Tech Radar noted it represented a "sea change" in the site's purpose, but the help forum was flooded with thousands of negative comments from critics who felt Yahoo had lost its mind.

August 2013

On October 3, 2017, the company stated that all 3 billion of its user accounts were affected by the August 2013 theft.

August 2013

The company reported two major data breaches of user account data to hackers during the second half of 2016. The first announced breach, reported in September 2016, had occurred sometime in late 2014, and affected over 500 million Yahoo! user accounts. A separate data breach, occurring earlier around August 2013, was reported in December 2016, and affected over 1 billion user accounts. Both breaches are considered the largest discovered in the history of the Internet. Specific details of material taken include names, email addresses, telephone numbers, encrypted or unencrypted security questions and answers, dates of birth, and encrypted passwords. Further, Yahoo! reported that the late 2014 breach likely used manufactured web cookies to falsify login credentials, allowing hackers to gain access to any account without a password.

August 20, 2013

Yahoo's corporate identity changed hands again in September 2021, when investment funds managed by Apollo Global Management acquired 90% of the company from Verizon. Under Apollo's ownership, Yahoo continued to retract its global footprint; in November 2021, the company announced it was ending operations in mainland China due to an increasingly challenging business and legal environment. This followed the earlier discontinuation of China Yahoo Mail on August 20, 2013. In 2023, Yahoo announced a 20% reduction in its workforce – shedding roughly 1,000 its 8,600 employees – joining a wave of mass layoffs sweeping the tech industry at companies including Google, Microsoft, Twitter, Meta, and Amazon.

November 21, 2014

To bolster its media and advertising presence, Mayer hired Katie Couric to anchor a new online news operation and launched an online food magazine. Yahoo further expanded its advertising capabilities on November 21, 2014, with the acquisition of Cooliris, and on December 12, it acquired video advertising provider BrightRoll for $583 million. Yahoo's acquisition strategy continued into the 2020s, targeting modern technology and financial platforms. In August 2023, the company acquired the San Francisco-headquartered social investing platform Commonstock, and in April 2024, it acquired the AI-driven news aggregator app Artifact.

February 02, 2016

Amid these internal crises and a $4.4 billion loss, Mayer announced layoffs amounting to 15% of the Yahoo workforce on February 2, 2016.

July 25, 2016

The mounting pressures and financial losses ultimately forced Yahoo to abandon its independence. On July 25, 2016, Verizon Communications announced it would acquire Yahoo's core Internet business for $4.83 billion, a stunning collapse from the company's peak valuation. The deal explicitly excluded Yahoo's 15% stake in Alibaba Group and its 35.5% stake in Yahoo Japan. However, the revelations regarding the data breaches forced a renegotiation; on February 21, 2017, Verizon lowered its purchase price by $350 million and reached an agreement to share liabilities related to the security failures.

June 13, 2017

Verizon completed the acquisition on June 13, 2017, marking the end of Yahoo as an independent company and prompting Mayer's resignation. Yahoo, AOL, and HuffPost were subsequently consolidated under a new umbrella subsidiary named Oath Inc. (later renamed Verizon Media), though the individual brands continued to operate under their own names. The remnants of the original Yahoo! Inc. that were not purchased by Verizon—primarily its stakes in Alibaba and Yahoo Japan—were spun off into a separate entity named Altaba, which was eventually liquidated after making a final distribution to shareholders in October 2020.

2018

The National Basketball Association partnered with Yahoo Sports to stream games, offer virtual and augmented-reality fan experiences, and in 2018 NBA League Pass. Yahoo Sportsbook launched in November 2019, a collaboration with BetMGM.

October 2019

In October 2019, a former Yahoo engineer, Reyes Daniel Ruiz, pleaded guilty to federal charges of illegally accessing user accounts. Ruiz had hacked about 6,000 users' accounts, including those of his friends, co-workers and many young women, seeking sexual images and videos.

2020

BuzzFeed acquired HuffPost from Yahoo in November 2020, in a stock deal with Yahoo as a minority shareholder. The NFL partnered with Yahoo in 2020, to introduce a new "Watch Together" function on the Yahoo Sports app for interactive co-viewing through a synchronized livestream of local and primetime NFL games. The Paley Center for Media collaborated with Verizon Media to exclusively stream programs on Yahoo platforms beginning in 2020.

September 2021

Yahoo became the main sponsor for the Pramac Racing team and the first title sponsor for the 2021 ESport/MotoGP Championship season. Yahoo, the official partner for the September 2021 New York Fashion Week event also unveiled sponsorship for the Rebecca Minkoff collection via a NFT space. In September 2021, it was announced that Yahoo partnered with Shopify, connecting the e-commerce merchants on Yahoo Finance, AOL and elsewhere.
