I couldn't think of anything beyond Nina Simon's examples of zoos or Britain's regulations on sales out of the country. Outside of museums, does it make sense to re-tool an institution to function like the Green Bay Packers? The community invests in the team and then gets returns on their investment.

Or like food co-ops where community members work within the store, have a say in the products, and daily operations?

Brief Google searches didn't immediately reveal anything that collaborative in public history.
