Illustrating the progression to hypervideo from hypertext, "Storyspace", a hypertext writing environment, employs a spatial metaphor for displaying links. It utilizes 'writing spaces', generic containers for content, which link to other writing spaces. in 1996 "HyperCafe", a popular experimental prototype of hypervideo, made use of this tool to create "narrative video spaces". It was developed as an early model of a hypervideo system, placing users in a virtual cafe where the user dynamically interacts with the video to follow different conversations.
