Baidu's new CTO will be an old friend of Robin Li, William Zhang, the former CTO of Infoseek. It is reported that Robin Li and William Zhang met for the first time in 1996, when Robin Li invented a search technology called "hyperlink analysis." At a computer conference held in Silicon Valley, he personally demonstrated and explained the application and prospects of hyperlink analysis. It was at this conference that he met William I. Chang, Infoseek's mobile technology expert at the time. Robin Li was subsequently recruited by William Zhang to join Infoseek to work on search engine development.
