1989, and the idea quickly spread to universities in the rest of the world.

Groups at the National Center for Supercomputing Applications at the University of

Illinois at Urbana-Champaign researched and extended Web technology. They developed

the first browser that was used at many sites, named Mosaic, in 1993. To allow the Web to

be accessed from a wide variety of computer systems, researchers built multiple versions of

Mosaic. Each version was designed to be used with a specific operating system, the

software that controls the computer. Within a year, computer programmer Marc Andreessen

had formed a commercial company, Netscape Communication, to built and sell Web

technologies.
