Mosaic was the web browser created at the National Center for Supercomputing Applications that helped popularize the World Wide Web.
NCSA Mosaic was developed at the University of Illinois Urbana-Champaign and released in 1993. Its user-friendly interface and ability to display images alongside text made the Web more approachable than earlier browsers, which often presented mostly text.
The project was led by Marc Andreessen and Eric Bina. Andreessen later co-founded Netscape, whose Navigator browser became highly influential during the commercial expansion of the Web.
Mosaic was not the first web browser; that distinction belongs to the browser created by Tim Berners-Lee. Mosaic’s importance was its accessibility and graphical presentation, which encouraged many people and organizations to explore online information.
