When he launched the Web in 1991, Tim Berners-Lee intended it to be used as a collaboration tool, which is why he was dismayed that the Mosaic browser did not give users the ability to edit the Web pages they were viewing. It turned Web surfers into passive consumers of published content. That lapse was partly mitigated by the rise of blogging, which encouraged user-generated content. In 1995 another medium was invented that went further toward facilitating collaboration on the Web. It was called a wiki, and it worked by allowing users to modify Web pages—not by having an editing tool in their browser but by clicking and typing directly onto Web pages that ran wiki software.
The application was developed by Ward Cunningham, another of those congenial Midwest natives (Indiana, in his case) who grew up making ham radios and getting turned on by the global communities they fostered. After graduating from Purdue, he got a job at an electronic equipment company, Tektronix, where he was assigned to keep track of projects, a task similar to what Berners-Lee faced when he went to CERN.
