In the 1980s, John Knoll and his brother Thomas began experimenting with a computer program to manipulate images.
Software companies thought they were crazy, because photographers didn't use computers at that time. Initially, the brothers called their program Display, then Imaginator, and finally they settled on Photoshop®.
Today Photoshop® is used by amateurs at home and professionals in business around the world.
A San Jose Mercury News article noted its place in popular language.
When something looks too good to be true, people say, "It must have been Photoshopped."
