From the start of Adobe Systems Incorporated (now Adobe, Inc.) exactly forty years ago in December 1982, the firm’s cofounders envisioned a new kind of printing press—one that was fundamentally digital, using the latest advances in computing.Initial discussions by cofounders Chuck Geschke and John Warnock with computer-makers such as Digital Equipment Corporation and Apple convinced them that software was the key to the new digital printing press.PostScript and the Adobe Type Library revolutionized printing and publishing, and kickstarted the explosive growth of desktop publishing starting in the 1980s.John Warnock championed the development of PDF in the 1990s, transforming PostScript into a technology that was safer and easier to use as the basis for digital documents, but retaining all the benefits of interoperability, fidelity, and quality.In particular, Warnock was impressed with the power of a procedural computer language he and John Gaffney helped to develop at the firm Evans and Sutherland, the “Design System.” In 1978, Chuck Geschke had just set up a new organization in the famed Xerox Palo Alto Research Center (PARC), the Imaging Science Laboratory."
