Vertical Integration in the Classical Hollywood Era

An important aspect of the studio system from the Classical Hollywood era is the U.S. market at the time and how it was vertically integrated.  The successes that came from the Classical Hollywood movie productions was contributed  by the consumer's support, the minute competition,  and the systematic consistency.  Vertical integration affected the production of films by making it "Fordistic," and less diverse.  By less diverse, I mean the actors were used and re-used, the scenes were all shot at the same site, and particular companies held all of the power needed to produce the desired product.    The studio would make films that the audience wanted to see.  Because of the simplicity of the hierarchy in production studios (AKA "the Big FIve" not including the three minor studios), it made it easier for the audience to communicate what films they intended on seeing.  An effect of audience feedback ultimately resulted in the evolution of genres.  The creation of genres allowed the audience to determine film popularity, for example the craze for "Gangster" or "Crime" movies.
