February 19, 1990: Adobe Photoshop 1.0 was released

1990Thomas Knoll was a student at the University of Michigan when he decided to write a program for his Macintosh Plus. The program was a simple image viewer, but when his brother – John Knoll – caught wind, he suggested that Thomas turn it into an image editor. Thomas took 6 months to develop the first version of the photo editing program. They then took the idea to Adobe, who snapped the idea up. At that point, Adobe Photoshop 1.0 was released. 23 years later, it is the premier image editing software for most. The first version only ran on Mac and because of the Monochromatic display, only created in black and white. There is not a day I go by without having to open up my version of Photoshop. I even used to do Photoshop contests – Here are some of the photoshops I did.
