On this day, 34 years ago, on August 6, 1991 (June 26, 1991 in the lunar calendar), Berners-Lee made his first World Wide Web public service on the Internet. Tim Berners-Lee, inventor of the World Wide Web and father of the Internet On August 6, 1991, Tim Berners-Lee posted an article about the World Wide Web project on the alt.hypertext newsgroup. The day also marks the first appearance of the World Wide Web public service on the Internet. Hypertext, a crucial concept in the World Wide Web, originated from several former projects in the 1960s. Examples include Ted Nelson's Project Xanadu and Douglas Engelbart's NLS. Both projects were inspired by Vanivar Bush's "memex" system for microfiche in his 1945 paper "As We Think". The earliest network ideas can be traced back to the EnQUIRE project built by Tim Berners-Lee in 1980. This is a hypertext online editing database similar to Wikipedia. Although the World Wide Web in use today is very different, they share many of the same core ideas, including some ideas in the next project after Berners-Lee's World Wide Web, the Semantic Web. In March 1989, Berners-Lee wrote the article "Suggestions on Information Management", which mentioned ENQUIRE and described a more sophisticated management model. On November 12, 1990, he collaborated with Robert Cailliau to propose a more formal proposal for the World Wide Web. On November 13, 1990, he wrote the first web page on a NeXT workstation to implement the ideas in his paper. During the Christmas holiday in 1990, Berners-Lee created all the tools necessary to work on the Internet: the first World Wide Web browser (and editor) and the first web server. Another brilliant breakthrough for Tim Berners-Lee was grafting hypertext onto the Internet. In his book "Weaving the Web", he explained that he had repeatedly advised users of the two technologies that a combination was feasible, but no one responded to his suggestions, and he finally had to solve the plan himself. He invented a unique authentication system for global network resources: the Unified Resource Identifier. On April 30, 1993, the European Organization for Nuclear Research announced that the World Wide Web would be free to anyone and would not charge any fees. Two months later, Gopher announced that it was no longer free, causing a large number of users to switch from Gopher to the World Wide Web. The World Wide Web Consortium (W3C), also known as the W3C Council. It was established in October 1994 at the Massachusetts Institute of Technology Computer Science Laboratory. The founder was Tim Berners Lee, the inventor of the World Wide Web.
