If the metaverse is viewed as an evolution of the Internet, its technical development can be traced back to 1968, when the ARPANET was created. However, the theory underlying the Internet, and especially today’s World Wide Web, has roots that go back even further [REDoJ]. As early as 1948, Vannevar Bush presented the theoretical concept of a networked information management and retrieval system in his article “As We May Think” in The Atlantic magazine [BUS45]. At that time, his considerations were still based on static documents, available in two-dimensional form as text and images. Nevertheless, Bush already recognized the necessity not only to store the documents themselves, but also to preserve the work performed on them for future research purposes. The user interface he outlined would still correspond to modern systems today, although the Memory Expander, or “Memex,” could not be technically realized at that time. Even so, the theoretical concept was revolutionary for its time.
