Through my research, I have come to the conclusion that the foundation of race film companies was definitely impacted by the Great Migration. The Great Migration impacted every aspect of society between 1910 and 1930, including film culture, and provided the necessary circumstances for production companies marketing to an African American audience to succeed.

The concentration of African Americans in urban areas of the North, as well as the rising consciousness of the impact of film on culture, led to the emergence of film companies in these areas of African American culture. The people of these new cultural centers needed entertainment that was relatable to them. Race film, particularly those produced by African American owned production companies, was the answer to this unfulfilled niche in the market. Figures such as Oscar Micheaux gained popularity during this time for their ability to combat harmful stereotypes portrayed by The Birth of a Nation (1915) and A Nigger in the Woodpile (1904) while remaining a great source of entertainment for the African American community.  In the data, we see spikes in the emergence in race film companies, particularly those owned by African Americans, after the release of Griffith’s film in 1915 (1916-1920), signifying that combating these stereotypes and providing entertainment for a marginalized spectator group was of great importance to African Americans. The societal outcomes of the Great Migration provided a vehicle for this to happen. 
While the Great Migration may not have been the only influence for the emergence of the 60+ race film producers  between 1910 and 1930, it certainly did create the conditions for a thriving industry.
