why ?

As Tim Berners-Lee was working at CERN he was faced with a few facts that would trigger him to muse about something that would later become the Web. These were:

• CERN's incredible abundance of knowledge and research
• CERN's equally abundance of different computer hardware/software, protocols, file formats, documentation systems
• == a bloody mess

Berners-Lee wanted to create some unified, global documentation system, that allowed CERN research team to document and share their progress in ways that would be readable, but also writable to others.

Berners-Lee's first efforts went to the development of a program called ENQUIRE.
