Photoshop was developed in 1987 by the American brothers Thomas and John Knoll, who sold the distribution license to Adobe Systems Incorporated in 1988. Thomas Knoll, a PhD student at the University of Michigan, began writing a program on his Macintosh Plus to display grayscale images on a monochrome display.
Adobe rebuffed the offer and instead continued to work on a new page layout application. The project had been started by Aldus and was code-named Shuksan. It was later code-named K2 and was released as InDesign 1.0 in 1999. In 2002, InDesign was the first Mac OS X-native desktop publishing (DTP) software.
