Microsoft is unquestionably the largest of the three companies, but between Sony and Nintendo it really depends on how you define larger. Nintendo produces far more profit and has a much larger market-cap but Sony’s revenue is much higher and is a much larger organization. In fact, because Nintendo is such a smaller organization which produces so much more profit on such smaller revenues is probably the reason Nintendo’s market-cap is so much higher than Sony’s; people invest in companies because of expectation of future growth, and Sony’s margins are so poor because increased competition is (slowly) eating them alive.
