It's hard to imagine that there's ever been a more profitible company than Apple. I've just been reviewing some astonishing facts, a number of which are summarized in the MBAOnline infographic below. During the December quarter Apple had revenues of $46 billion, of which $13 billion was profit. Just to put that in perspective, in the same quarter Wal-Mart (the world's largest retailer) had more revenue than Apple, at $109 billion — BUT Wal-Mart's profit was $3.3 billion. Apple's profit was four times larger — yet it spends 3 times less on operations than Wal-Mart.
