Photoshop is the image editing software available. Over 3 million copies have been sold, and it’s expensive so I can only imagine how many pirated copies are installed.

This is a short history of the origins of Photoshop.

Summary:

• The software was developed in the 80’s by John Knoll (with the help of his brother Thomas).
• The earliest version had no user interface – you had to type in commands.
• Early versions were completely in black and white.
• John couldn’t find anyone who wanted to sell Photoshop. Eventually a company selling scanners licensed it.
• Things only really took off when Adobe got hold of the software and released it in 1990
