The headline of the article says How Aamir discovered Hindi Cinema's biggest market, but in fact the article does not say anything about how Aamir or anyone discovered the potential market. The article merely states the fact of the box office returns of the movies. Also more and more Indian movies are being made ready for Chinese audience, so its a market not only for Hindi but for any Indian language(of course Hindi movies will get better visibility because of their huge budgets).
