For the first seven months of 1991, the World Wide Web operated almost exclusively as an internal utility within the high-energy physics research community at CERN. Tim Berners-Lee and his small team refined the server software, expanded the directory of available documents on `info.cern.ch`, and demonstrated the system at technical workshops. However, for the Web to achieve its intended purpose, it needed to expand beyond CERN and become a global infrastructure accessible to anyone connected to the Internet.
On August 6, 1991, Tim Berners-Lee publicly announced the World Wide Web project to the internet community by posting a detailed summary on the `alt.hypertext` Usenet newsgroup. His message explained the objectives of the project, described how to download the line-mode browser, provided instructions for running web servers, and included a hypermedia link to the world's first publicly accessible web page hosted at `http://info.cern.ch/hypertext/WWW/TheProject.html`.
This public announcement invited software developers, academic institutions, and computer hobbyists worldwide to experiment with the protocol, write independent browser interfaces, and set up their own web servers. Berners-Lee and CERN made a crucial strategic decision to offer the core code, protocols, and documentation freely without asserting proprietary control or charging license fees, encouraging rapid, royalty-free adoption across global networks.
The posting on August 6, 1991, is widely celebrated as the public birth date of the World Wide Web. In the months following the Usenet post, independent developers around the world began building alternative browsers—such as ViolaWWW, MidasWWW, and eventually NCSA Mosaic—sparking an exponential expansion of web servers and transforming an obscure physics documentation tool into a ubiquitous global network.
Why it matters
Making info.cern.ch public on Usenet introduced the World Wide Web to the broader internet community outside CERN. By inviting universal participation and maintaining the technology as open and royalty-free, Tim Berners-Lee catalyzed the exponential global adoption that built the modern internet economy and digital society.
Interesting fact
No screenshot or backup file of the original website page precisely as it appeared on August 6, 1991 exists; the earliest preserved version of the info.cern.ch website dates from November 1992, restored by CERN in 2013.

Quotes
"The WorldWideWeb (WWW) project aims to allow links to be made to any information, anywhere."
"Had the technology been proprietary, and in my total control, it probably would not have taken off. You can't propose that something be a universal space and at the same time keep control of it."
