Xanadu, the ultimate hypertext information system, began as Ted Nelson's quest for personal liberation. The inventor's hummingbird mind and his inability to keep track of anything left him relatively helpless. He wanted to be a writer and a filmmaker, but he needed a way to avoid getting lost in the frantic multiplication of associations his brain produced. His great inspiration was to imagine a computer program that could keep track of all the divergent paths of his thinking and writing. To this concept of branching, nonlinear writing, Nelson gave the name hypertext.
