It is one of the largest AI and Internet companies in the world. The holding company of the group is incorporated in the Cayman Islands. Baidu was incorporated in January 2000 by Robin Li and Eric Xu. The Baidu search engine is currently the sixth largest website in the Alexa Internet rankings. Baidu has origins in RankDex, an earlier search engine developed by Robin Li in 1996, before he founded Baidu in 2000.

Baidu offers various services, including a Chinese search engine, as well as a mapping service called Baidu Maps. Baidu offers about 57 search and community services, such as Baidu Baike (an online encyclopedia), Baidu Wangpan (a cloud storage service), and Baidu Tieba (a keyword-based discussion forum).

Baidu Global Business Unit (GBU) is responsible for Baidu's international products and services for markets outside of China. Baidu GBU's product portfolio includes keyboard apps Simeji and Facemoji Keyboard, content recommendation platform popIn, augmented reality network OmniAR, Japanese smart projector popIn Aladdin, and ad platform MediaGo, which is focused on Chinese advertisers looking to reach overseas users.

The partnership was extended in 2019.

In 2018, Baidu divested the "Global DU business" portion of its overseas business, which developed a series of utility apps including ES File Explorer, DU Caller, Mobojoy, Photo Wonder and DU Recorder, etc. This business now operates independently of Baidu under the name DO Global.

Baidu has the second largest search engine in the world, and held a 76.05% market share in China's search engine market.

History

Early development

In 1994, Robin Li (Li Yanhong, 李彦宏) joined IDD Information Services, a New Jersey division of Dow Jones and Company, where he helped develop software for the online edition of ''The Wall Street Journal''. He also worked on developing better algorithms for search engines and remained at IDD Information Services from May 1994 to June 1997.

In 1996, while at IDD, Li developed the RankDex site-scoring algorithm for search engines results page ranking"About: RankDex"
, ''rankdex.com'' and received a US patent for the technology. Launched in 1996, RankDex was the first search engine that used hyperlinks to measure the quality of websites it was indexing. Li referred to his search mechanism as "link analysis," which involved ranking the popularity of a web site based on how many other sites had linked to it. It predated the similar PageRank algorithm used by Google two years later in 1998; Google founder Larry Page referenced Li's work as a citation in some of his U.S. patents for PageRank. Li later used his RankDex technology for the Baidu search engine.

Baidu was incorporated on January 18, 2000, by Robin Li and Eric Xu. In 2001, Baidu allowed advertisers to bid for ad space and then pay Baidu every time a customer clicked on an ad, predating Google's approach to advertising. In 2003, Baidu launched a news search engine and picture search engine, adopting a special identification technology capable of identifying and grouping the articles.

Baidu went public on Wall Street through a variable interest entity (VIE) based in the Cayman Islands on August 5, 2005.

On July 31, 2012, Baidu announced that it would team up with Sina to provide mobile search results.

On November 18, 2012, Baidu announced that it would be partnering with Qualcomm to offer free cloud storage to Android users with Snapdragon processors.

On August 2, 2013, Baidu launched its Personal Assistant app, designed to help CEOs, managers and the white-collar workers manage their business relationships.

On May 16, 2014, Baidu appointed Dr. Andrew Ng as chief scientist. Dr. Ng will lead Baidu Research in Silicon Valley and Beijing.

On July 18, 2014, the company launched a Brazilian version of the search engine, ''Baidu Busca''.

On October 9, 2014, Baidu announced acquisition of Brazilian local e-commerce site Peixe Urbano.

In April 2017, Baidu announced the launch of its Apollo project (Apolong), a self-driving vehicle platform, in a bid to help drive the development of autonomous cars including vehicle platform, hardware platform, open-source software platform and cloud data services. Baidu plans to launch this project in July 2017, before gradually introducing fully autonomous driving capabilities on highways and open city roads by 2020. In September 2017, Baidu launched a $1.5 billion autonomous driving fund to invest in as many as 100 autonomous driving projects over the ensuing three years. At the same time, Apollo open-source software version 1.5 was also launched.

In June 2017, Baidu partnered with Continental and Bosch, auto industry suppliers, on automated driving and connected cars.

In September 2017, Baidu rolled out a new portable talking translator that can listen and speak in several different languages. Smaller than a typical smartphone, the 140-gram translation device can also be used as a portable Wi-Fi router and is able to operate on networks in 80 countries. It is still under development. Baidu will also be inserting artificial intelligence (AI) technology into smartphones, through its deep learning platform. At the same period, it has also led a joint investment of US$12 billion with Alibaba Group, Tencent, JD.com and Didi Chuxing, acquiring 35% of China Unicom's stakes.

In October 2017, according to ''The Wall Street Journal'', Baidu would launch self-driving buses in China in 2018. In the same month, Baidu announced that its first annual Baidu World technology conference (''Bring AI to Life'') would be held and live-streamed on November 16, 2017, at China World Summit Wing and Kerry Hotel, bringing together Baidu executives, employees, partners, developers, and media to discuss the company's mission and strategy, technology breakthroughs, new product developments, and its open artificial-intelligence (AI) ecosystem.

In August 2021 Baidu revealed a new Robocar concept said to be capable of Level 5 autonomous driving. It also comes with the latest second-generation AI chip that can analyse the internal and external surroundings to provide predictive suggestions to proactively serve the needs of passengers.

Domain name redirection attack

On January 12, 2010, Baidu.com's DNS records in the United States were altered such that browsers to baidu.com were redirected to a website purporting to be the Iranian Cyber Army, thought to be behind the attack on Twitter during the 2009 Iranian election protests, making the proper site unusable for four hours. Internet users were met with a page saying "This site has been attacked by Iranian Cyber Army". Chinese hackers later responded by attacking Iranian websites and leaving messages.
Baidu later launched legal action against Register.com for gross negligence after it was revealed that Register.com's technical support staff changed the email address for Baidu.com on the request of an unnamed individual, despite failing security verification procedures. Once the address had been changed, the individual was able to use the forgotten password feature to have Baidu's domain passwords sent directly to them, allowing them to accomplish the domain hijacking. The lawsuit was settled out of court under undisclosed terms after Register.com issued an apology.
