In the early 1980s, when personal computing first became a reality, the faces of glowing terminals had an almost magical aura, transubstantiating arcane passages of 1s and 0s into sensory experience. In fact, the seemingly impenetrable complexity of what was unfolding behind the screen created a sense of mystery and wonderment. We were in awe of the hackers who could unlock the code and conjure various illusions from it; they were modern magicians who seemed to travel between two worlds: reality and cyberspace. One day, we imagined, these sages of cyberspace would leave their bodies behind and fully immerse themselves in the secret world behind the screen. Such images manifested themselves through the decades in films like Tron, Hackers, and The Matrix and in the fiction narratives of the cyberpunk genre. When the public internet first emerged, images of cyberspace were already deeply embedded in our collective imagination; these images have become the primary lens through which we view and evaluate our online activity. For this reason, tracing the genealogy of the cyberspace concept reveals much about present cultural assumptions regarding our relationship with information technology.
