> Thomas Knoll, a PhD student in computer vision at the University of
> Michigan, had written a program in 1987 to display and modify

> effects company Industrial Light & Magic, found it useful for
> editing photos, but it wasn?t intended to be a product. Thomas said,
> ?We developed it originally for our own personal use?it was a lot a
> fun to do.?
>
> Gradually the program, called ?Display?, became more sophisticated.
> In the summer of 1988 they realized that it indeed could be a
> credible commercial product. They renamed it ?Photoshop? and began
> to search for a company to distribute it. About 200 copies of
> version 0.87 were bundled by slide scanner manufacturer Barneyscan
> as ?Barneyscan XP?.
