History of electronic text:
•Historically, when a manuscript is given to a copy editor for grammatical and formatting edits, it contained a scribbles of codes in the margins which told the typesetter how the final print out should look like.

•Charles started to use same idea of typographic in computer texts and it is called general markup.
•As a result of this, instead of marking a piece of text with " 36pt Times Roman" , he could label it as a "Title".
•This process help made searching by specifications more easy than before.
•In 1970s , Goldfarb , Edward Mosher and Ray Lorie developed a system of encoding info a bout a document's structure by using a set of tags. They called it GML(Generalized Markup Language).
•Then GML was developed to be used around world and called SGML (ISO 8879).
