It’s 1992, and in the basement of the chemistry building at the University of Illinois at Urbana-Champaign, two computer science students are working on a new web browser. Up to this point, browsing has made up less than one percent of all internet traffic, but Marc Andreessen and Eric Bina are about to change all that. Fueled by a combination of Pepperidge Farm cookies, Skittles and hubris, Andreessen and Bina emerge from the basement with Mosaic, the user-friendly web browser that will popularize the internet—if it doesn’t crash the school’s server first.
