Happy Birthday! The World Wide Web is 20 years old

Happy Birthday! The World Wide Web is 20 years old

20 years ago today, on April 30 1993, CERN contributed the technologies underpinning the World Wide Web to the royalty-free public domain. On 30 April 1993 CERN published a statement that made World Wide Web (“W3”, or simply “the web”) technology available on a royalty-free basis. By making the software required to run a web server freely available, along with a basic browser and a library of code, the web was allowed to flourish.

British physicist Tim Berners-Lee invented the web at CERN in 1989. The project, which Berners-Lee named “World Wide Web”, was originally conceived and developed to meet the demand for information sharing between physicists in universities and institutes around the world. In 1989 and 1990, Berners-Lee began toying with the idea of an information management system, where hypertext pages (records) are linked together via hyperlinks. This might seem obvious now, but the web was really the first system to achieve this kind of interlinking on a broad scale. Prior to hypertext, all that existed was searchable databases, with no way to jump between pages and records.

These simple technologies — the humble URL, HTTP, and HTML — were developed by Tim Berners-Lee at CERN in the early ’90s, but it wasn’t until they were open-sourced that the WWW actually became the web. To accompany hyperlinks, Berners-Lee also created the UDI (universal document identifier), which would later be known as the URL (uniform resource locator) or URI (uniform resource identifier). The basic concept of URLs is to provide a single, global format that can be used to describe or locate any resource on the web, irrespective of where the resource is hosted, which web server software is hosting it, which protocol is being used (HTTP, FTP), and which ISP is connecting that resource to the internet.

The final corner of the WWW tech triad was HTTP, which stands for Hypertext Transfer Protocol. HTTP is essentially a client-server protocol for getting HTML pages from a server, and (though this wasn’t in the original spec) posting data from the client to the server. Berners-Lee had created HTML and URLs, but without HTTP there was no way to serve HTML pages from a server, and no way for a client to request a URL from a server. Incidentally, Berners-Lee also wrote the first HTTP server, called CERN httpd, to serve the world’s first website (hosted at http://info.cern.ch). As a fun aside, all of Berners-Lee’s early WWW work was done on a NeXT Computer (created by Steve Jobs, after he left Apple in the ’80s. See: The technology legacy of Steve Jobs, former CEO of Apple).


To celebrate the WWW’s 20th birthday, CERN has re-released Berners-Lee’s original website, at its original address: http://info.cern.ch/hypertext/WWW/TheProject.html.

Berners-Lee developed a simple text-based browser called WorldWideWeb in 1990 to accompany the project, but it wasn’t until the release of Mosaic by the National Center for Supercomputing Applications (NCSA) in 1993, following the open-sourcing of the WWW technologies, that the web really began to grow in earnest. Mosaic was a free-for-non-commercial-use graphical browser developed by Marc Andreessen and Eric Bina, with funding from Al Gore’s High Performance Computing and Communication Act of 1991. After graduating from university Andreessen went on to form the Mosaic Communications Corporation, in 1994 Mosaic changed its name to Netscape, in 1997 the first Browser War was sparked by Microsoft’s release of Internet Explorer 4 .

As for Tim Berners-Lee, he went on to found the World Wide Web Consortium (W3C) at MIT, with support from DARPA, after leaving CERN in 1994.  From there, he continues to guide the development of standardized, open web technologies, and thus the future of the web. The W3C’s primary goal is to ensure the continued compatibility of dozens of browsers, used by billions of surfers, accessing millions of web servers.


About Art Selectronic

Art Selectronic is an artist-led initiative, that supports grass-roots contemporary art that remains unswayed by fashion, trends or the whims of government funding. The project involves ongoing research into the placing of contemporary art, it’s audiences and it’s relationship to the everyday. We place great emphasis on context. Our mission is to support new works of contemporary art and foster an audience from a wide range of backgrounds.
