The World Wide Web (WWW) was created in 1990 by British CERN physicist Tim Berners-Lee. On 30 April 1993, CERN announced that the World Wide Web would be free to use for anyone. Prior to the introduction of HTML and HTTP, other protocols such as File Transfer Protocol and Gopher protocol are used to retrieve individual files from a server. These protocols provide a simple directory structure that browses the user and selects the files to download. Documents are presented more frequently as plain text files or encoded in word processor formats.

Websites can be the work of an individual, a company or another organization, and usually is devoted to a subject or for a particular purpose. Any website can contain a hyperlink to any other website, so the distinction between individual sites, as perceived by the user, can be blurred.
