Archie – the first search engine

Three university students Alan Emtage, Peter Deutsch and Bill Heelen launched a search engine called Archie. The search engine enabled its users to find and download specific files on the Internet by indexing files stored on public FTP servers. Its name comes from the word archive, dropping the letter v. Archie is often considered to be the world’s first Internet search engine ever. At the end of the 1990s, the search engine gradually ceased to exist.

WorldWideWeb – the first browser

At CERN, a Swiss research center, a British physicist and internet pioneer Tim Berners-Lee created the world’s first web browser, called WorldWideWeb. The browser was also a simple WYSIWYG (What You See Is What You Get) editor for editing web pages. WorldWideWeb only worked with the NeXTStep operating system. Later, the browser was renamed Nexus to avoid confusion with the World Wide Web (WWW).

XHTML originated from an integration of XML and HTML and was divided into three versions: Strict, Transitional, and Frameset. According to W3C’s original plans, XHTML was supposed to be the successor to HTML, whose development was completed by version 4.01. However, in 2007, a new version of HTML started being developed, labeled HTML5.
