While we now take crisp-looking typography for granted, it wasn't always that way. Back in the 80s, low-res fonts looked dreadful—but fortunately two men changed all that.

When John Warnock and Chuck Geschke left Xerox PARC in 1982, they had with them years of experience in computer graphics, laser printers, fonts and design. In time, they set up Adobe, developed the PostScript typography language, and solved the problem of hideous fonts for good. In this video, Professor Brailsford from the University of Nottingham tells their fascinating story. [Computertphile]
