CERN has reconstructed the original WorldWideWeb browser from 1989, allowing users to experience the humble beginnings of modern internet browsing. The WorldWideWeb application, developed at CERN in December 1990, served as the antecedent to today's web browsers. This reconstruction project marked the 30th anniversary of the original browser's creation.

The original browser ran on NeXT computers at CERN, representing one of the first graphical web interfaces. Developers rebuilt it within contemporary browsers to preserve this piece of internet history. The project received support from the US Mission in Geneva through the CERN & Society Foundation, highlighting the browser's cultural significance.

Users can now navigate using the original interface by launching the browser, selecting "Document" from the side menu, and entering URLs in the reference field. This reconstruction offers a tangible connection to web's origins, demonstrating how far digital interaction has evolved from its simple beginnings.
