Although commonly used as a synonym for the Internet, the World Wide Web (WWW or simply the Web) is a hypertext media service that runs on the Internet. Separate from other Internet services such as email or FTP, the Web is the world of webpages, hyperlinks, search engines, and URL addresses. British computer scientist Sir Tim Berners-Lee, working at CERN in 1989, wrote a proposal defining the WWW and is credited as its inventor.
