Graphical User Interface Timeline

This timeline lists all of the graphical user interface environments that I have been able to find information about through my own research and on the Internet. I want to be as historically accurate as I can, however due to limited available information there may be some mistakes. See my notes section at the bottom of this page for known inaccuracies. If you see an error and have additional information about it please e-mail me.

Notes:
I am limiting this timeline to systems that provide GUI services to other applications, this is why I am not including individual graphical DOS apps or older graphical programs such as Sketchpad .

I am also not listing each version of a GUI system unless a significant change has occurred in it. MacOS has kept the same basic user interface since Version 1 and is therefore only mentioned a couple of times. Microsoft, on the other hand thinks it is fun to make users learn a completely new interface every few years, so each of the Windows interfaces is listed.

Issues:
X could just about have it's own history page. There is no way I can list all of the different appearances of X here so I am just mentioning it's creation. The picture is much more recent and not of the original X.
The picture of NextStep is of a later version.
The picture of PC-Geos is from Geos Ensemble 2.X with the presentation manager look.
The picture of BeOS is from a later version.
The color Mac screen shot is of MacOS 7.5.5, although these machines shipped with MacOS 6
I have insufficient information about the history of Tandy Deskmate and the Apollo workstation to place them on this timeline.
