World Wide Web
The World Wide Web, also known as the WWW and the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser in 1990 while employed at CERN near Geneva, Switzerland. The browser was released outside CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.
Internet metaphors
The very first metaphor to describe the Internet was the World Wide Web proposed in 1989. However, uncertainty surrounding the structure and properties of the Internet was apparent in the newspapers of the 1990s that presented a vast array of contradicting visual models to explain the Internet. Spatial constructs were utilized to make the Internet appear as a tangible entity placed within a familiar geographical context. A popular metaphor adopted around the same time was cyberspace coined by William Gibson in his novel "Neuromancer" to describe the world of computers and the society that gathers around them.
