Version 1.0 of the web browser Mosaic is released by the National Center for Supercomputing Applications. It’s the first software to provide a graphical user interface for the emerging World Wide Web, including the ability to display inline graphics. The lead Mosaic developer is Marc Andreesen, one of the future founders of Netscape.
My first experience with the World Wide Web was in 1993 using Mosaic on a Mac in my dorm’s computer lab. I had no idea what I had discovered until a few months later.
