Hello, World

In December 1990, an application called WorldWideWeb was developed on a NeXT machine at the European Organization for Nuclear Research (CERN) just outside Geneva. This program is the antecedent of most of what we consider or know as “the web” today.

In February 2019, to celebrate the thirtieth anniversary of WorldWideWeb’s development, a group of developers and designers convened at CERN to rebuild the original browser within a contemporary browser, allowing users around the world to experience the humble origins of this transformative technology.

The project was supported by the US Mission in Geneva through the CERN & Society Foundation.

Party like it’s 1989
