Whose idea was the World Wide Web?

The World Wide Web was invented by Sir Tim Berners-Lee, a British computer scientist, who proposed it in 1989 while working at CERN, the European physics laboratory near Geneva. He wanted a better way for scientists around the world to share and link information, and he combined existing ideas into a powerful new system. He created the three core technologies that still underpin the web: HTML, the language for creating web pages; URLs, the addresses that identify them; and HTTP, the protocol for transferring them. By 1991 the web was made available beyond CERN, and crucially, Berners-Lee and CERN made the technology free for everyone to use, without patents or fees, which allowed it to spread explosively. It is important to distinguish the web, a system of linked pages, from the internet, the underlying network on which it runs.
