First Known Use of MARKUP LANGUAGE
markup language noun (Concise Encyclopedia)
Standard text-encoding system consisting of a set of symbols inserted in a text document to control its structure, formatting, or the relationship among its parts. The most widely used markup languages are SGML, HTML, and XML. The markup symbols can be interpreted by a device (computer, printer, browser, etc.) to control how a document should look when printed or displayed on a monitor. A marked-up document thus contains two types of text: text to be displayed and markup language on how to display it.
