Baidu, Inc. (Chinese: ??; pinyin: B?id?, pronounced BY-doo in English), incorporated on January 18, 2000, is a Chinese web services company headquartered in the Baidu Campus in Haidian District in Beijing.[3] Baidu offers many services, including a Chinese language-search engine for websites, audio files, and images. Baidu offers 57 search and community services including Baidu Baike, an online collaboratively built encyclopedia, and a searchable, keyword-based discussion forum.[4] Baidu was established in 2000 by Robin Li and Eric Xu. Both of the co-founders are Chinese nationals who studied and worked overseas before returning to China. In October 2012, Baidu ranked 5th overall in the Alexa Internet rankings.[5] During Q4 of 2010, it is estimated that there were 4.02 billion search queries in China of which Baidu had a market share of 56.6%. China's Internet-search revenue share in second quarter 2011 by Baidu is 76%[6] In December 2007, Baidu became the first Chinese company to be included in the NASDAQ-100 index.[7] As of January 2014, Baidu's market capitalization amounted to approximately $55 billion.[8] It is considered one of the most successful Internet startups of all time by market capitalization, revenue, growth and cultural impact.[9] Baidu provides an index of over 740 million web pages, 80 million images, and 10 million multimedia files.[10] Baidu offers multimedia content including MP3 music, and movies, and is the first in China to offer Wireless Application Protocol (WAP) and personal digital assistant (PDA)-based mobile search. Baidu released its low-cost smartphone, Changhong H5018.[11] It is similar to Wikipedia as an encyclopedia, however, unlike Wikipedia only registered users can edit the articles. While access to Wikipedia has been blocked in China since October 2005, there is some controversy about the degree to which Baidu cooperates with Chinese government censorship.[12]
