Back in the early days, the internet was a much different creature than it is today. To most, it would be unrecognizable, primarily consisting of bulletin board systems with no multimedia aside from a few low-res inline images. These systems were disparate and had to be dialed into separately.

The internet changed drastically with the advent of the World Wide Web. All of those previously separate systems were connected, but the world needed a way to "browse" them---a "web browser" was in order. In April 1994, Marc Andreessen and Jim Clark founded the Mosaic Communications Corporation. Mosaic was the name of a software that allowed users to access different content on the web. Andreessen had worked on the project while he was with the National Center for Supercomputing Applications (NCSA) at the University of Illinois.
