The history of Photoshop.

Photoshop began with Thomas Knoll is 1987, and with his pixel imaging program entitled Display. His Display software was designed to showcase grey scale images on a black-and-white monitor, and he quickly knew that there was a future for his project. After partnering with his brother, John Knoll, Thomas and John began adding features to Display that allowed it to process digital image files. Eventually, this caught the attention of Adobe as well as some early adapters to the industry, and the software was licensed and renamed to Photoshop in 1989. In 1990, the software was then finalized, and began shipping.

Over the next 25 years, Photoshop would adapt the digital photography era, and become the most successful tool for photographers everywhere. As competing software would spring up and fade out, Photoshop would continue to innovate and be part of the leading software in terms of technology and tools available.
