The first commercial web browser released to the public was Mosaic, launched in 1993. This web browser played a pivotal role in popularizing the Internet by providing a user-friendly interface that combined text and images. Mosaic's development by Marc Andreessen and others at the National Center for Supercomputing Applications (NCSA) laid the foundation for subsequent browsers and web technologies. Its impact was profound, helping to drive the commercial adoption of the web and influencing modern browser design.
