=The World Wide Web (WWW)=
A world wide documentation system, sometimes known as the Web, same times as WWW

==Web's creation==
* conceptualized by Tim Berners-Lee at CERN
* As response to his frustration with the difficulty to share information inside and outside CERN
** diversity of computers with different systems
** large number of projects and individuals
** large amounts of information with no common system to organize and communicate this information

==Web: publish and find information==
Tim Berners-Lee wanted to create a system that would:
* give access to files in different computers around the world.
* link the files among themselves
* facilitate the location and retrieval of information 

"''Suppose all the information stored in computers everywhere were linked … Suppose I could program my computer to create '''a space in which anything could be linked to anything'''.'' All the bits of information in every computer at CERN, and on the planet, would be available to me and anyone else. These would be a single information space". <ref>Berners-Lee, Tim. Weaving the Web. London: TEXERE, 2000.</ref>

==How==
Tim Berners-Lee 
* devised a system that connected information through '''links''' (hypertext)
* created a '''hyper text language''': '''HTML''' (Hyper Text Markup Language)
* wrote an '''interpreter for HTML''' (that transforms HTML code into visual form): a '''web browser''' <ref>[http://line-mode.cern.ch/www/hypertext/WWW/TheProject.html Simulation of the first Web Browser]</ref>
* implemented a systems of addresses - URL - that allowed files in remote computers to be called and reply by sending back a (usually) HTML file.

==Result==
* The Web became a system where information was easier to find
* users of host computers (servers) could easily decide what they said to the world, and also change it
* users became publishers of content on the Web (not even needing access to a server in order to do it)
* that publishing possibility and will triggered the creation of web publishing services and formats (Geocities, blogs, Tumblrs, Facebook walls ,etc)
* in this context the user is not only a consumer, but also a producer of content (or publisher)
