==History==
===Early development===
In 1987, Thomas Knoll started work on a simple program to display grayscale graphics on a Mac. The result, in January 1988, was Display 0.07. His brother John Knoll convinced him to to turn Display into a full image editing application which was initally named "ImagePro" and then evolved into the prototype Photoshop 0.63. An alpha version 0.87 was licensed to Barneyscan in a short-term deal and shipped with about 200 of their slide scanners as "BarneyScan XP".Thomas and John Knoll by Jeff Schewe, Photoshop News, originally published in PEI Magazine. 2000-09.
The Knoll brothers demonstrated the software to Apple Computer and then Adobe Systems in September 1988. Fred Mitchell, Adobe's head of acquisitions, had been evaluating ColorStudio from at the time, but felt that the Knoll Software product was better. Mitchell immediately committed to a distribution license for Photoshop with a handshake and the final agreement was signed in April 1989. Adobe explored different names for the product, but decided to stick with "Photoshop" for version 1.0. In February 2013, the source code of version 1.0.1 was donated to the .Adobe Photoshop Source Code by Len Shustek, The Computer History Museum.
