Problem:
I need to write a paper that identifies and describes how the "business model" used by eBusinesses evolve over time, using at least three examples. I could use your help for some good examples might be eBay, Amazon, Netflix, Napster, Facebook and Google, which have all evolved significantly from their original business model. However, you may choose any example you might prefer. A "business model" is not the same as a "revenue model", the business model encompasses all aspects of a business' operations - the revenue model might be one aspect of a business model.
