25 years ago, the web opened up and the world changed

On April 30, 1993, CERN—the European Organization for Nuclear Research—announced that it was putting a piece of software developed by one of its researchers, Tim Berners-Lee, into the public domain.  That software was a “global computer networked information system” called the World Wide Web, and CERN’s decision meant that anyone, anywhere, could run a website and do anything with it. In an era when online services were still dominated by proprietary, for-profit walled gardens such as AOL and CompuServe, that was a radical idea.
