Tim Berners-Lee is the man who wrote the software(软件)programme that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners-Lee both worked on one of the earliest commercial(商业的)computers and talked about their work at home. As a child he would build models of computers from packaging material. After graduating from Oxford University he went on to the real thing. In the 1980s scientists were already communicating using a primitive version(原始版本)of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a programme, which let him store these messages. This gave him another idea: write a programme that will let academics(学术界人士)from across the world share information on a single place. In 1990 he wrote the HTTP(服务程序所用的协议)and HTML(超文本链接标示语言)programmes which form. the basis of the World Wide Web.

The next year his programmes were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used his codes(编码)to work with different operating systems. New things like web browsers(浏览器)and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000.

In 1994 Tim Berners-Lee formed the newly formed World Wide Web Consortium(协会)，or W3C. More than 200 leading companies and laboratories are represented(代表)by W3C. Together they make sure that everyone can share equally on the web. "The Web can help people understand the way that others live and love and are human. It helps us understand the humanity of people, "he says.
