In the press release about its earnings, Amazon highlighted original programming coming from Amazon Studios.

Given Amazon's history of prioritizing investment ahead of income, investors often look to its margins for a window into when its profitability will ramp up. In the first quarter, Amazon's operating margins as a percent of consolidated sales slipped to 2.7 percent, from 3 percent a year ago. The company's North American operating margin grew to 4.9 percent, up from 4.7 percent in the year ago period.
