Page "Brian Behlendorf" Paragraph 5

While developing the first online, for-profit, media project — the HotWired web site for Wired Magazine — in 1994, they realized that the most commonly used web server software at the time ( developed at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign ) could not handle the user registration system that the company required.

So, Behlendorf patched the open-source code to support HotWired's requirements.
