After a little study of the netflix market, here is a representation of its feedback loops. We can appreciate the positive and negative feedback between each variable present on the netflix market

Based on the Market and Price simulation model in System Zoo 3. Used in the System Thinking section of Regenerative Economics.

Jay Forrester's "Market Growth as Influenced by Capital Investment" model as rebuilt by Eric Stiens

Based on the Market and Price simulation model in System Zoo 3, Z504. In this model the profit calculations were not realistic. They were based on the per unit profit, which does not take items not sold into account. Also the model was not very clear on profit since it was included in the total production costs and consequently in the unit costs and subsequently profit was calculated by subtracting unit costs of the market price. Thus profit had a double layer which does not make the model better accessible. I have tried to remedy both in this simplified version.

This model is made to illustrate the components that impact profitability on a basic level.

Based on the Market and Price simulation model in System Zoo 3, Z504. I made some more intrusive changes that make the model more realistic, or more 'economic', in another version 'simplified and improved'. 

market causal loop diagram
more sales create more revenue
more revenue generates more money for product developement and profit

This diagram is intended as an illustration for a text in the Regenerative Economics textbook. I didn't build it to simulate it.
