[inforoots] GUIs and glass teletypes

[Stan Sieler]

There'a an article about the history of GUIs in Ars Technica, at
http://arstechnica.com/articles/paedia/gui.ars

However, examining the accompanying graph at

made me wonder ... what about glass teletypes?

It seems to me that there's a critical piece missing from most GUI
histories: the impact of CRTs, as in "glass teletypes", on the development
of the GUI (including the impact of UCSD Pascal's user interface).

I.e., moving to a CRT terminal (not graphics yet) led to a 
conceptual breakthrough:

   text / information doesn't have to be presented in a linear fashion,
   or in a manner where it scrolls out of sight.

(Many CRT teminals had cursor positioning that allowed information to 
be placed at arbitrary locations, and some had the ability to say 
"don't scroll this away")

Did this have an affect on GUI development?

Aside from Englebart and his radar background, I wonder if most GUI 
developers were first exposed to "glass teletypes"?
