Yesterday on February 19th, Adobe Photoshop celebrated its 25th birthday. It’s hard to believe that 25 years ago the first version of the venerable photo manipulation software was launched. 

While it probably doesn't get the attention that other important innovations of the late 20th century get, such as the personal computer, Photoshop is still one of the most influential inventions of the time. When you think about how much of the visual world we live in today has been influenced by computer graphics in one way or another, from advertising to movies, and much of that can be traced back to Photoshop.
