http://www.nma.tv/ Subway is now the world's largest fast food chain, with more locations than McDonalds. The company prides itself on its relatively healthy menu, with spokesman Jared Fogle reportedly having last 245 pounds while on the "Subway diet." Unlike other restaurants, Subway is a private company with low franchise costs, though it finds other ways to make money by nickel-and-diming franchisees. McDonalds remains the world's No. 1 franchise based on sales.
