In January 1993, Marc Andreessen and Eric Bina, students at the University of Illinois's NCSA, launch Mosaic, the first web browser combining text and images on the same page with an accessible graphical interface. Before Mosaic, accessing the World Wide Web (created by Tim Berners-Lee at CERN in 1989) required command-line tools. Mosaic's inline images, hyperlink navigation, and multi-platform availability eliminate the technical entry barrier; web traffic multiplies exponentially in the following months. Andreessen later founds Netscape (1994). Mosaic marks the beginning of the commercial Internet era.
