Why is Marc Andreessen a known figure in Information Technology?

          Marc Andreessen is an American inventor best known for developing Mosaic, the first widely used web browser. He also co-founded Netscape Communications.

          During his under graduation at the University of Illinois, Andreessen worked at the National Centre for Supercomputing Applications (NCSA), and got himself acquainted with Tim Berners-Lee’s concept of open standards for the World Wide Web. Andreessen, along with Eric Bina, then worked on creating a user friendly browser that could be worked on a wide range of computers. That was the birth of the Mosaic Web Browser, in 1993.

          He then founded the Mosaic Communications Corporation, and worked on the commercial possibilities of the Mosaic browser. However, after the University of Illinois objected to the use of the company name, it was changed to Netscape Communications, and the web browser got a new name – the Netscape Navigator.

          In October 2005, Andreessen along with entrepreneur Gina Bianchini launched Ning, a venture that provides platform for social networking sites.
