Ok maybe I should've said first widely used browser. Once we had protocols some of us were using the Web, probably not "browsing" we knew where to find the info. Yeah Gopher protocol was different. Mosaic seemed to work and it worked out well for Andreessen and University of Illinois.
In the Web's first generation, Tim Berners-Lee launched the Uniform Resource Locator (URL), Hypertext Transfer Protocol (HTTP), and HTML standards with prototype Unix-based servers and browsers. A few people noticed that the Web might be better than Gopher. In the second generation, Marc Andreessen and Eric Bina developed NCSA Mosaic at the University of Illinois. Several million then suddenly noticed that the Web might be better than sex.
