to reach fruition when Nelson was forced to return the project's rented Data General Nova minicomputer due to financial exigencies. Nelson has stated that some aspects of his vision are being fulfilled by Tim Berners-Lee's invention of the World Wide Web, but he dislikes the World Wide Web, XML and all embedded markup – regarding Berners-Lee's work as a gross over-simplification of his original vision: HTML is precisely what we were trying to PREVENT— ever-breaking links, links going outward only, quotes you can't follow to their origins, no version management, no rights management. Jaron Lanier explains the difference between the World Wide Web and Nelson's vision, and the implications: A core technical difference between a Nelsonian network and what we have become familiar with online is that [Nelson's] network links were two-way instead of one-way. In a network with two-way links, each node knows what other nodes are linked to it. ... Two-way linking would preserve context. It's a small simple change in how online information should be stored that couldn't have vaster implications for culture and the economy. Other projects In 1957, while a student, Nelson co-wrote and co-produced what he describes as a pioneering Rock Musical. Entitled "Anything and Everything", it was produced and performed at Swarthmore College. In 1965, he presented the paper "Complex Information Processing: A File Structure for the Complex, the Changing, and the Indeterminate" at the ACM National Conference, in which he coined the term "hypertext". In 1976, Nelson co-founded and briefly served as the advertising director of the "itty bitty machine company", or "ibm", a small computer retail store that operated from 1977 to 1980 in Evanston, Illinois. The itty bitty machine company was one of the few retail stores to sell the Apple I computer. In 1978, he had a significant impact upon IBM's thinking when he outlined his vision of the potential of personal computing to the team that three years later launched the IBM PC. From the 1960s to the mid-2000s, Nelson built an extensive collection of direct advertising mail he received in his mailbox, mainly from companies selling products in IT, print/publishing, aerospace, and engineering. In 2017, the Internet Archive began to publish it online in scanned form, in a collection titled "Ted Nelson's Junk Mail Cartons". ZigZag As of 2011, Nelson was working on a new information structure, ZigZag, which is described on the Xanadu project website, which
