Amazon just announced its Q3 2014 earnings, showing the largest operating loss in company history of $544 million for the quarter. That's dramatically higher than the $25 million operating loss of Q3 2013, despite the fact that net sales were up 20 percent to $20.58 billion this quarter. Operating cash flow was also up for the quarter at $5.71 billion, but that still is in the shadow of such a large loss.
