Adobe Systems is the software company that, more than any other, shaped how computers describe and reproduce printed and on-screen documents. It was founded in 1982 by John Warnock and Charles “Chuck” Geschke. In his Computer History Museum oral history, recorded in 2018, Warnock recounts how he and Geschke met at Xerox PARC’s Imaging Sciences Laboratory, where they worked on a page-description system called Interpress, and how their frustration with Xerox’s reluctance to release that technology led them to leave and start their own company.
The company’s first product was PostScript, the page-description programming language. According to the Computer History Museum, which released early PostScript source code with Adobe’s support in 2022, Warnock led the team that built it, and PostScript “became an essential ingredient in the desktop publishing industry, accelerating computing’s transformation of printing and driving Adobe’s growth as a renowned software company.” PostScript reached the public in 1985 through the Apple LaserWriter, the first PostScript printer, a collaboration that Warnock discusses in his oral history.
From that foundation Adobe built a portfolio that defined professional graphics and publishing. Illustrator brought PostScript’s outline-based vector drawing to designers; Photoshop became the dominant tool for editing raster images; and in 1993 Acrobat introduced PDF, the fixed-layout document format Adobe derived from PostScript. The same outline-font technology that powered PostScript also made Adobe a major force in digital typography, producing and licensing typefaces and helping define font formats used across the industry.
Adobe’s history illustrates a recurring pattern in computing: foundational ideas born in a corporate research lab reaching the wider world only after their inventors left to commercialize them independently. Interpress stayed largely inside Xerox, while PostScript, carrying the same core ideas into a startup, transformed an industry. The founders’ decision to publish detailed specifications for their formats, even while the products were commercial, also helped PostScript and later PDF become broadly supported rather than locked to Adobe’s own software.
The company continued to evolve well beyond its origins, moving into web, video, and subscription-based creative software, but its lasting historical significance rests on the early work of Warnock and Geschke. The pairing of PostScript with the laser printer and the personal computer put professional-quality typesetting on ordinary desktops, and the later standardization of PDF gave the world a durable, vendor-neutral way to exchange documents.
