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 for him hundreds and thousands of times in the crowd, suddenly turning back by chance, I find him 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 him 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.[11]  He also did work on better algorithms for search engines. He 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 [12][13][14] and received a US patent for the technology.[15] He later used this technology for the Baidu search engine.

Baidu offers a number of services to locate information, products and services using Chinese-language search terms, such as, search by Chinese phonetics, advanced search, snapshots, spell checker, stock quotes, news, knows, postbar, images, video and space information, and weather, train and flight schedules and other local information.

Baidu sees China's rural areas as great potential for electronic business (e-business), evidenced by the fact that revenue grew the fastest from agriculture, forestry, animals and fishery in the company's keyword promotion project, a crucial source of Baidu's total revenue.

[edit] Domain name hacked

On 12 January 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.[26] Internet users were met with a page saying "This site has been attacked by Iranian Cyber Army".[27] Chinese hackers later responded by attacking Iranian websites and leaving messages.[28] 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.[29][30]
