The Internet vs The World Wide Web

The terms Internet and World Wide Web (or just "the Web") are often used interchangeably to mean the same thing - I do this myself. While it's not important for most of us to know the difference in the grand scheme of things, it's interesting to at least know that there is a differentiation.

At it's most straightforward, just think of the Web is part of the Internet. The Internet is the large interconnected network that allows the web to exist. The World Wide Web is a hypertext document system that operates via the Internet.

Hypertext was a revolutionary concept of putting linked content in a document; something we take so much for granted now that it's difficult to imagine life without it.
The World Wide Web was invented by Sir Tim Berners-Lee; whilst he was working at CERN. Berners-Lee first proposed a "Hypertext project" on the 12st of March, 1989. Berners-Lee was assisted in developing the World Wide Web by Robert Cailliau; Cailliau helped Berners-Lee write a proposal for funding for the project, and remained a "key" supporter of the project. Berners-Lee proposed "Hypertext system" was intended to be used for documents at CERN; only at a later date was the scope of the project expanded.
