Abstract:

Innovations build on existing perceptions and structures - at least until the new ideas are fully manifested. Then, the innovation discards the shackles of the old model and stands on its own merits and strengths. The development of video is often used to support this phenomenon. Video was initially used only to tape existing live stage performances - a new concept built on the perceptional structure of the existing. True innovation in this medium did not occur until someone recognized the uniqueness of video, and the limitations of live stage shows.
