|“||Many people have asked about the meaning of our name. 'Baidu' was inspired by a poem written more than 800 years ago during the Song Dynasty. The poem compares the search for a retreating beauty amid chaotic glamour with the search for one's dream while confronted by life's many obstacles. '...hundreds and thousands of times, for her I searched in chaos, suddenly, I turned by chance, to where the lights were waning, and there she stood.' Baidu, whose literal meaning is hundreds of times, represents persistent search for the ideal.||”|
The name "Baidu" is a quote from the last line of Xin Qiji's classical poem "Green Jade Table in The Lantern Festival" saying: "Having searched thousands of times in the crowd, suddenly turning back, She is there in the dimmest candlelight."
The context of the poem is that in ancient China, girls had to stay indoors and the Lantern Festival was one of the few times they could come out. In the sea and chaos of lantern lights, they would sneak away to meet their love and exchange promises to meet again next year.
A summary of the entire poem: Flowers bursting into bloom in the sky, stars falling like rain (fireworks/meteor shower), Whole streets filled with perfume, jeweled horses pulling ornate carriages, fish and dragon lanterns dancing throughout the entire night. A body decorated with golden thread and butterfly trinket, laughter that has a subtle fragrance. Having searched for this person until exhaustion, when suddenly turning back by chance, I find her standing lonely in the far end of the street in the waning light.
In 1994, Robin Li joined IDD Information Services, a New Jersey division of Dow Jones and Company, where he helped develop a software program for the online edition of The Wall Street Journal. He also did work on 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 and received a US patent for the technology. He later used this technology for the Baidu search engine.
On 31st July 2012, Baidu announced they will team up with Sina to provide mobile search results.

In an August 2010 The Wall Street Journal article, Baidu has played down its benefit from Google's moving its China search service to Hong Kong, but Baidu's share of revenue in China's search—advertising market grew six percentage points in the second quarter to 70%, according to Beijing-based research firm Analysys International.
It is also evident that Baidu is attempting to enter the internet social network market. As of 2011 This plan, if executed, would face off Baidu with competition from the two popular Chinese social networks Renren and Kaixin001 as well as induce rivalry with instant-messaging giant, Tencent QQ.
, it is discussing the possibility of working with Facebook, which would lead to a Chinese version of the international social network, managed by Baidu.
According to the China Digital Times, Baidu has a long history of being the most proactive and restrictive online censor in the search arena. Documents leaked in April 2009 from an employee in Baidu's internal monitoring and censorship department show a long list of blocked websites and censored topics on Baidu search. In May 2011, pro-democracy activists sued Baidu for violating the U.S. constitution by the censorship it conducts in accord with the demand of the Chinese government.
Domain name hacked
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 actual 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 their 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 pull off the domain hijacking.
Pay per click
Baidu has adopted a commercial advertising model called keyword-bidding (without censorship, and focusing on profit). Officially called pay per click (PPC), it requires companies to pay for select keywords that will link to the company's website through the Baidu Search engine. What's more, companies can buy the ranking position in Baidu's natural search result. In August 2011, China Central Television revealed that commercial model of Baidu which is against the official internet policy in China and allegedly jeopardizes China's internet development.
DNA Copyright technology
In April 2012, Baidu applied for a patent for its breakthrough in DNA copyright recognition technology. This technology will automatically scan files that are uploaded by internet users, and recognize and filter out content that may violate copyright law. This will allow Baidu to offer an infringement free platform.  
Baidu workers arrested
On August 6, 2012 the BBC reported that three employees of Baidu were arrested on suspicion that they accepted bribes. The bribes were allegedly paid for deleting posts from the forum service. Four people were fired in connection with these arrests.
