You always have control. Some want control of receiving information the moment it happens. It will be these individuals that will drive real time. I view this the same way people view sports. People that watch sports want it real time because everyone discusses it as it happens (or immediately after). If the media you are consuming is important to discussions in approximate real time, then it will be important to receive that media as it happens. This obviously doesn't fit everything, sports is just an example where it does.
