Happy 25th Birthday World Wide Web!

March 12 was the 25th anniversary of the World Wide Web, otherwise known simply as the Web, a system of interlinked hypertext documents accessed via the Internet. On that day in 1989, Tim Berners-Lee, a British computer scientist and engineer at CERN, wrote a proposal to his administrators for developing an effective communication system to be used by the organization’s members.

He eventually realized the wider applications of this concept, and teamed up with Belgian computer scientist Robert Cailliau in 1990 to further refine the concept of a hypertext system that would “link and access information of various kinds as a web of nodes in which the user can browse at will”. Hypertext is simply text displayed on a computer with references to other text via “hyperlinks”. Berners-Lee finished the first website in December of that year, which you can still see here (for information on the first image ever uploaded, which was a GIF, click here). 

It’s amazing how far it’s come since that humble page , and where the web will be another 25 years from now. Berners-Lee actually shares his thoughts on the future of the Internet in general here and I recommend you give it a read.

Note that despite being used interchangeably, the Internet and the Web are two distinct things: the former is a massive networking infrastructure that connects millions of computers together globally — a network of networks, so to speak. Information that travels over the Internet does so via a variety of languages known as protocols.

The Web, on the other hand, is a way of accessing that information using the HTTP protocol, which is one of only many languages used in the Internet to transmit data. Email, for example, relies on the SMTP protocol, and therefore isn’t technically part of the Web.
