The very first web browsers, such as Lynx, were character-based applications without a graphical user interface to be seen. It may look hopelessly primitive today, but in their time, 1991-1993, they were great. Unlike most of the other early browsers, Lynx, introduced in 1992, is still being maintained, and Unix and Linux shell users still use it today.

The very first graphical web browser was Viola, which was created in 1991. Heavily influenced by Apple HyperCard, this Unix X Window System browser was invented by Pei-Yuan Wei, a Taiwanese computer science student. He had been working on hyperlinks and the internet, and had he been a bit faster off the mark, he (and not Tim Berners-Lee) might have gone down in history as the inventor of the World Wide Web.

Mosaic was the first widely-popular graphical web browser . It was first available on Unix in 1993, but it was quickly ported to the Mac and Windows PC. It set both the look of the web browser today, and both Firefox and Internet Explorer can trace their roots to its original code. 

By 1993, people outside of the scientific community were learning about the web and they wanted to be able to use it from Windows PCs instead of Unix workstations. So it was that Tom Bruce developed the first web browser for Windows: Cello. Bruce did this in conjunction with his work on the Legal Information Institute (LII), the first legal information site on the web. 

Do you think Internet Explorer 1.0 looks a lot like Mosaic? Well, it should; it was actually a version of Mosaic that had been customized for Windows by a company named Spyglass. You see, at the start of the web, Bill Gates didn't think it would ever amount to much. By 1995, he'd realized the error of his ways and rushed IE into the then brand-new Windows 95.

In the meantime, Mosaic's inventors had gone on to produce their own commercial web browser: Netscape, which was introduced in 1994. In its early years, Netscape was the dominant web browser. Microsoft, however, forced the company out of business in the late 90s. While Microsoft was eventually found guilty of anti-trust behavior, it came too late to save Netscape.
