Co-founder of Netscape









Browsing the Internet in the early 1990s meant that a user had to perform a rather cumbersome series of steps. Andreessen decided to create an interface so that retrieval of information could be accomplished more easily. NCSA MOSAIC was the result and he offered it for free on the Internet to the joy of many early users. This was all before Andreessen graduated college. After graduating, he joined James Clark, the founder of Silicon Graphics in California and they co-founded Netscape Communications.
