I want to know the answer to the following question:
What model of ownership is commonly used in American professional sports?
All the background I'm provided with is that "Prior to that, the league followed the franchise model more common in North American professional sports leagues; each team essentially operated as its own business and the league itself was a separate entity which in exchange for franchise fees paid by the team owners provided rules, officials, scheduling and the other elements of organizational structure.". Is that enough to answer the question?
Answer: yes
