The name we give a technology is based on our view of what it is and shapes our vision of what it might become. They looked like horse-drawn wagons without the horses. People saw and imagined nothing beyond that. Yet today's cars bear little resemblance in form or capabilities to their horse-drawn predecessors. This has happened time and again.
People view any new technology in terms of what came before.
Early photographers took formal portraits, as painters did previously. Like the carriage without the horse , some see electronic media nothing more than books that you read on a computer. As usual, this will change as we begin to understand what the new medium can do. The words we use should broaden our vision, not force us to wear blinders. You can argue, of course, that to a limited degree all media are interactive.
