The Web

The World Wide Web (WWW) or simply the Web was created in 1989 by Tim Berners-Lee at CERN (European Center for Nuclear Research), as a simple way to publish information and make it available on the Internet.  

The Web is based on the concept of hyperlinks that make it possible to link text and images in one document to other documents or objects creating a web of connected hyper-documents.  These hyper-documents are known by Web pages and are created using the Hypertext Markup Language (HTML).
