The raster graphics editing software Photoshop, currently produced by Adobe Systems, was originally created in 1988 by brothers John and Thomas Knoll. The first retail version of Photoshop was released exclusively for Apple Macintosh computers in 1990.

The original program created by Thomas Knoll was called Display. It was much simpler, but his brother John was impressed and thought it was similar to software he used on his job at Industrial Light and Magic. After further development, the program was called ImagePro, but the name was changed due to a conflict with an existing software. By the time Apple first saw it in 1998, it had been named Photoshop, and the name stuck.
