film industry cultural economy development

This is a course on cultural and economic development. The final project of our group needs to be completed based on 20 questions. I am responsible for four of them. They are:

-What business models have developed to accommodate digitalization?

-Give some examples of the A list/B list ranking.

-Who are the gate-keepers in this industry?

-Who are the ‘certifiers’ in the industry? What is their economic role?

You need to analyze these four issues from the film industry and finish writing.
