There is not even a clear definition what indie is. LucasFilm is multi-billion company and is indie, another indie company made a movie which I think is the best movie of all times: "The Man From Earth" with a $10000 budget, any schoolboy who makes something free or commercial is an indie, people who make something which is free of all rules and habits is indie. Indie just means independant, and it can be indepandant of anything: money, culture, society, rules, ideas, people, or even it's own definition
