Build the highway and watch the town grow . At first a few shops appear and maybe a restaurant . Then a hotel opens . Eventually new houses are built . A village is born .

This is also how the virtual world has developed . Think of the Internet as the road carrying information between two computers . Think of the World Wide Web as the village . At first it is just a place on the virtual road where travelers meet . More travelers come bringing new kinds of information . New villages are started .

Every village has a founder . Tim Berners Lee is the man who wrote the software program that led to the foundation of the World Wide Web . How did he get the idea ? He tells us on his own website : “ One of the things computers were not able to do was store contacts from different sources . The dream behind the Web is of a common space in which we communicate by sharing information.”

Tim Berners Lee could have followed the Microsoft route by forming a company to sell the programs he invented . Or he could have joined an existing company . But in his view the Web is a language , not a product . Charging a fee for using his programs would have slowed the growth of the Web . And other companies would make similar products to compete . Instead of one World Wide Web there would be several smaller Webs . Each would use incompatible (不相容的)software . The Web is valuable because it uses a common computer language to reach people and share information . Competing Webs would lose this value .Imagine if somebody sent you a bill every time you spoke a word of English .

In 1994 Tim Berners Lee formed World Wide Web Consortium , or W3C. More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone no matter what their equipment or software is can work equally on the Web .

“The Web can help people to understand the way that others live and love . It helps us understand the humanity of people ,” he says .
