Sir Tim Berners-Lee is a British computer scientist. He was born in London, and his parents were early computer scientists, working on one of the earliest computers. Growing up, Sir Tim was interested in trains and had a model railway in his bedroom. He recalls: “I made some electronic gadgets to control the trains. Then I ended up getting more interested in electronics than trains. Later on, when I was in college I made a computer out of an old television set.” After graduating from Oxford University, Berners-Lee became a software engineer at CERN, the large particle physics laboratory near Geneva, Switzerland. Scientists come from all over the world to use its accelerators, but Sir Tim noticed that they were having difficulty sharing information. “In those days, there was different information on different computers, but you had to log on to different computers to get at it. Also, sometimes you had to learn a different program on each computer. Often it was just easier to go and ask people when they were having coffee…”, Tim says. Tim thought he saw a way to solve this problem – one that he could see could also have much broader applications. Already, millions of computers were being connected together through the fast-developing internet and Berners-Lee realised they could share information by exploiting an emerging technology called hypertext. In March 1989, Tim laid out his vision for what would become the web in a document called “Information Management: A Proposal”. Believe it or not, Tim’s initial proposal was not immediately accepted. In fact, his boss at the time, Mike Sendall, noted the words “Vague but exciting” on the cover. The web was never an official CERN project, but Mike managed to give Tim time to work on it in September 1990. He began work using a NeXT computer, one of Steve Jobs’ early products. Tim’s original proposal. Image: CERNBy October of 1990, Tim had written the three fundamental technologies that remain the foundation of today’s web (and which you may have seen appear on parts of your web browser):
Tim also wrote the first web page editor/browser (“WorldWideWeb.app”) and the first web server (“httpd“). By the end of 1990, the first web page was served on the open internet, and in 1991, people outside of CERN were invited to join this new web community. As the web began to grow, Tim realised that its true potential would only be unleashed if anyone, anywhere could use it without paying a fee or having to ask for permission. He explains: “Had the technology been proprietary, and in my total control, it would probably not have taken off. You can’t propose that something be a universal space and at the same time keep control of it.” So, Tim and others advocated to ensure that CERN would agree to make the underlying code available on a royalty-free basis, forever. This decision was announced in April 1993, and sparked a global wave of creativity, collaboration and innovation never seen before. In 2003, the companies developing new web standards committed to a Royalty Free Policy for their work. In 2014, the year we celebrated the web’s 25th birthday, almost two in five people around the world were using it. Tim moved from CERN to the Massachusetts Institute of Technology in 1994 to found the World Wide Web Consortium (W3C), an international community devoted to developing open web standards. He remains the Director of W3C to this day. The early web community produced some revolutionary ideas that are now spreading far beyond the technology sector:
New permutations of these ideas are giving rise to exciting new approaches in fields as diverse as information (Open Data), politics (Open Government), scientific research (Open Access), education, and culture (Free Culture). But to date we have only scratched the surface of how these principles could change society and politics for the better. In 2009, Sir Tim co-founded the World Wide Web Foundation with Rosemary Leith. The Web Foundation is fighting for the web we want: a web that is safe, empowering and for everyone. Please do explore our site and our work. We hope you’ll be inspired by our vision and decide to take action. Remember, as Tim tweeted during the Olympics Opening Ceremony in 2012, “This is for Everyone”.
Important Note: This text is intended as a brief introduction to the history of the web. For a more detailed account, you might want to consider reading:
Thanks to the efforts of Paul Kunz and Louise Addis, the first Web server in the US came online in December 1991, once again in a particle physics laboratory: the Stanford Linear Accelerator Center (SLAC) in California. At this stage, there were essentially only two kinds of browser. One was the original development version, which was sophisticated but available only on NeXT machines. The other was the ‘line-mode’ browser, which was easy to install and run on any platform but limited in power and user-friendliness. It was clear that the small team at CERN could not do all the work needed to develop the system further, so Berners-Lee launched a plea via the internet for other developers to join in. Several individuals wrote browsers, mostly for the X-Window System. Notable among these were MIDAS by Tony Johnson from SLAC, Viola by Pei Wei from technical publisher O'Reilly Books, and Erwise by Finnish students from Helsinki University of Technology. Early in 1993, the National Center for Supercomputing Applications (NCSA) at the University of Illinois released a first version of its Mosaic browser. This software ran in the X Window System environment, popular in the research community, and offered friendly window-based interaction. Shortly afterwards the NCSA released versions also for the PC and Macintosh environments. The existence of reliable user-friendly browsers on these popular computers had an immediate impact on the spread of the WWW. The European Commission approved its first web project (WISE) at the end of the same year, with CERN as one of the partners. On 30 April 1993, CERN made the source code of WorldWideWeb available on a royalty-free basis, making it free software. By late 1993 there were over 500 known web servers, and the WWW accounted for 1% of internet traffic, which seemed a lot in those days (the rest was remote access, e-mail and file transfer). 1994 was the “Year of the Web”. Initiated by Robert Cailliau, the First International World Wide Web conference was held at CERN in May. It was attended by 380 users and developers, and was hailed as the “Woodstock of the Web”. As 1994 progressed, stories about the Web hit the media. A second conference, attended by 1300 people, was held in the US in October, organised by the NCSA and the newly-formed International WWW Conference Committee (IW3C2). By the end of 1994, the Web had 10 000 servers - 2000 of which were commercial - and 10 million users. Traffic was equivalent to shipping the entire collected works of Shakespeare every second. The technology was continually extended to cater for new needs. Security and tools for e-commerce were the most important features soon to be added.
