Industry-specific REA Model help?

p>For my Accounting Information Systems class my assignment is to draw an REA diagram (that is, resources, events and agents) of a business process for my assigned industry, which is the entertainment industry. The problem is, I don’t really know what the main business process for an entertainment company like a film production company would be. I don’t know how most of their money is generated(events), and who is involved in that process(agents). I know the entertainment industry also has a wide-spectrum, from films to music, etc., but I’m open to doing my assignment on any facet of the industry, I just need help understanding how these types of industries work.
