I can't say I agree. That said, I'm not quite sure what you mean by "a more efficient production cycle, from artist to consumer". And I'm not sure how "[reducing the] cycle time between artist conception of an entertainment pitch and consumers evaluating it" is related to distribution. Could you elaborate?
Presently, from an artist getting say a film concept to the first audience seeing it, is a gap of several years. A lot of this is necessary, e.g. time for plot refinement. Other stuff, like negotiating with unions for lighting or going through bureaucratic licensing and distribution hurdles, is not.
Lean Start-up says reducing this cycle time should make the system fitter.
