Since the 1940s, people have always dreamed of having a worldwide information base. In this information base, information can not only be accessed by people all over the world, but also be easily linked to information in other places, so that users can obtain important information conveniently and quickly.

Hypertext is an important concept in the World Wide Web, which originated from several projects in the 1960s.

For example, Xanadu by Ted Nelson and NLS by douglas engelbart. The inspiration of these two projects comes from the memex system designed by Nivard Bush for microfilm in the paper "Think Like We Think" in 1945.

Another brilliant breakthrough of Tim Berners Lee is the grafting of hypertext onto the Internet. In his book "Weaving the Web", he explained that he had repeatedly suggested to the users of these two technologies that it was feasible to combine them, but no one responded to his suggestion, so he finally had to solve the scheme himself. He invented the unique authentication system of global network resources: uniform resource identifier.
