Nauman's Narrative Engine

I do no know a large amount about current media, so my understanding of a "loop" is very elementary, but I think I can extract a few basic ideas out of Manovich's piece. He asks, in one part, "Can the loop be a new narrative form appropriate for the computer age?" He explained how current narratives are more linear, due to how actual, real human experience is linear. Yet, due to bandwidth and storage limitations, he claims loops may not be a thing of the past. He calls it the new narrative engine because the loop, in the current computer age, drives a lot of the media. For example, although a computer game maybe appear to be progressing linearly, the bad guys may be walking back and forth across the screen. They are programmed by a loop. Also, more generally, he explains that computer programs while running and seemingly moving forward, are actually completely programmed on loops. Thus, loops are very prevalent and drive a lot of new media due to hardware limitations.
The way I thought of this when I read this piece was by relating it to some of Bruce Nauman's videos from his exhibit, "A Rose Has No Teeth." For example, the video of him falling into a corner, over and over and over again. This is on a loop. It is true that he performed this in person for a very long time, but he did not do it over and over and over again. He therefore used this video on a loop due to physical restrictions, as well as spacial restrictions (as he could not perform this stunt over and over and over again in multiple places.) Thus, the loop is used due to limitations.
