The Hypertext Editing System, or HES, was an early hypertext research project conducted at Brown University in 1967 by Andries van Dam, Ted Nelson, and several Brown students.[2] HES organized data into two main types: links and branching text.The branching text could automatically be arranged into menus, and a point within a given area could also have an assigned name, called a label, and be accessed later by that name from the screen.Although HES pioneered many modern hypertext concepts, its emphasis was on text formatting and printing.HES required an IBM 2250 display console and a large memory partition on Brown's IBM System/360 Model 50 campus mainframe computer which limited its use: "Although it was shared with others, it was a multi-million-dollar piece of technology housed in a large machine room that van Dam’s team was able to use as essentially a personal computer between midnight and 4 AM.
