Marc Andreessen (born 1972) has been one of the key players in making the Internet and World Wide Web accessible to the masses, thanks to his development of Netscape Navigator, a browser that integrates text, graphics, and sound.

The astronomical growth of the World Wide Web could not have occurred without a simple product that helped users find their way through the vast, and sometimes disorganized, material on the Web. The first such product, called a browser, was invented by a team including software developer and entrepreneur, Marc Andreessen. He developed the Mosaic program as a college student. It later became the Netscape Navigator when he co-founded his own company in 1994. This browser software had a profound impact on society. According to some estimates, Mosaic stimulated a 10,000 percent increase in the number of Web users within two years from its debut, and Netscape Navigator was even more popular.
