Adobe Photoshop, the imaging software that continues to redefine creativity in the digital age, turns 25. Photoshop is one of the most recognized software brands in the world with tens of millions of users, and is the go-to application for digital image manipulation across all media: from print, to film, to the Web. How it all began? In 1987, Thomas Knoll developed a pixel imaging program called Display. It was a simple program to showcase grayscale images on a black-and-white monitor. However, after collaborating with his brother, John Knoll, the two began adding features that made it possible to process digital image files. The program eventually caught the attention of industry influencers, and in 1989, Adobe made the decision to license the software, naming it Photoshop and shipping the first version in 1990. “Adobe thought we’d sell about 500 copies of Photoshop a month,” said Thomas Knoll, Adobe Fellow and Photoshop co-creator. “Not in my wildest dreams did we think creatives would embrace the product in the numbers and ways they have.”
