Historically video editing has been one of those operations shaped by technology. For decades it depended on VTRs to play and record. You had to go to an edit room, usually darkened and with loads of buttons and winking lights, to get your edit done by a video editor. It was not cheap. Then, with video stored on computer discs, editing went nonlinear, was much faster and more flexible, the control interface became a GUI and costs started to come down.
