Wikipedia has some hilarious text, referring to the pre-WYSIWYG world as though it is dead and gone:
“Before the adoption of WYSIWYG techniques, text appeared in editors using the system standard typeface and style with little indication of layout (margins, spacing etc.). Users were required to enter special non-printing control codes (now referred to as markup code tags) to indicate that some text should be in boldface, italics, or a different typeface or size.”
