Marc Andreessen is perhaps best known for being the Co-founder of Netscape Communications Corp. He has also served as Chief Technology Officer of AOL (after AOL acquired Netscape).
In addition, he is Co-founder and Chairman of Ning and an investor in several start-ups, including Digg, Plazes, and Twitter. He is a General Partner at Andreessen Horowitz, and Andreessen sits on Facebook's board of directors.
Born in rural Cedar Falls, Iowa, in 1971, Andreessen has always had a deep interest in computers. By the sixth grade, he'd created a virtual calculator to do his math homework. By seventh grade, he was writing his own games for his family's Commodore 64 computer.
In 1992, while working at the the National Center for Supercomputing Applications (NCSA), Andreessen developed Mosaic, a visual browser to help navigate the emerging volumes of information available on the young Internet. Later, Mosaic changed its name to Netscape and became one of the most popular Web browsers to date.
Andreessen holds a degree in Computer Science from the University of Illinois at Urbana-Champaign.
