What do you think mainframes running MVS and VM/CMS were?
What were things like air traffic control?
The 'desktop' is a fuzz concept that gets confused with a GUI.
Those mainframes - think airline ticket and reservation - could handle many hundreds of remote terminals, keeping them updated.
What's a dumb terminal if not the ultimate in 'thin clients'?
You betcha its not!
