Ted Nelson demonstrates Xanadu Space, his software for representing hypertext in three-dimensional space with linked, referenced content fragments.

Ted Nelson explains the original Xanadu hypertext idea of visible connection, the notion that links between documents should be shown and preserved. He argues that the Web and current document standards lost this concept.

Ted Nelson, the originator of hypertext and Project Xanadu, gives a personal account at age 80 of his ideals, his career, and how a poor career plan led to discoveries and adventures. It works as an alternative history of personal computing and hypertext.

A short excerpt from Werner Herzog's film Lo and Behold in which Ted Nelson lays out his ideas about hypertext and interconnection. Herzog concludes that Nelson is the only sane person in computing.

Joe Armstrong, creator of Erlang, and Jeremy Ruston, creator of TiddlyWiki, discuss hypertext, Ted Nelson's idea of intertwingled knowledge, and a way to combine TiddlyWiki with Erlang. It is a Code Mesh LDN 2018 talk.

A 1979 CBC radio interview in which Ted Nelson tries to explain how computers could serve as tools for thinking and visualizing. The interviewer keeps failing to grasp the idea, and Nelson patiently answers again and again.

Joe Armstrong's GOTO 2018 talk contrasts the problems computer scientists study with the problems users have. He revisits forgotten great ideas such as tuple spaces, flow-based programming, Xanadu and Unix pipes, with anecdotes.
