Implementations Besides the already mentioned Project Xanadu, Hypertext Editing System, NLS, HyperCard, and World Wide Web, there are other noteworthy early implementations of hypertext, with different feature sets: thumb|right|190px|Hypertext Editing System (HES) IBM 2250 Display console – Brown University 1969 FRESS – a 1970s multi-user successor to the Hypertext Editing System. ZOG – a 1970s hypertext system developed at Carnegie Mellon University. Electronic Document System – an early 1980s text and graphic editor for interactive hypertexts such as equipment repair manuals and computer-aided instruction. Information Presentation Facility – used to display online help in IBM operating systems. Intermedia – a mid-1980s program for group web-authoring and information sharing. HyperTies - a mid-1980s program commercially applied to hundreds of projects, including July 1988 Communications of the ACM and Hypertext Hands-On! book. Texinfo – the GNU help system. KMS – a 1980s successor to ZOG developed as a commercial product. Storyspace – a mid-1980s program for hypertext narrative. Document Examiner - an hypertext system developed in 1985 at Symbolics for their Genera operating system. Adobe's Portable Document Format – a widely used publication format for electronic documents. Amigaguide – released on the Commodore Amiga Workbench 1990. Windows Help – released with Windows 3.0 in 1990. Wikis – aim to compensate for the lack of integrated editors in most Web browsers. Various wiki software have slightly different conventions for formatting, usually simpler than HTML. PaperKiller – a document editor specifically designed for hypertext. Started in 1996 as IPer (educational project for ED-Media 1997). XML with the XLink extension – a newer hypertext markup language that extends and expands capabilities introduced by HTML.
