We have Thomas Knoll to thank for
the program we know as "Photoshop". Back in 1987 Thomas was a
PhD student at the University of Michigan. Being interested in
photography, he started writing a program which he named "Display"
on a Macintosh to display grayscale images. He was encouraged
by his brother, John, to turn it into a editing program. This
new program was first called "ImagePro" and latter renamed
"Photoshop". The first commercial version of "Photoshop" was
distributed with a scanner manufactured by Barneyscan. This
was only a short-term deal and Adobe purchased the license in 1989.
In 1990 "Photoshop 1.0 was released.

In 2004 "Photoshop" was renamed
"Photoshop CS" (Creative Suite) to indicate its integration with the other Adobe CS
programs: Illustrator and InDesign.
