- The Lumiere Projector of 1895;

The approach can be considered as an example of 'teleological history', which is the concept of history goes towards an assumed and clearly defined end. In the context of film technology it would be towards realism.
The use of teleological historiography is very problematic and there is significant evidence that proves the approach fails to properly explain the history of film technology.
A better way to consider the history of film technology is to view it as the effect of a range of complex forces where each new technology developed and distributed can be regarded as an event. Tied into the event is a convergence of generative mechanisms.
