In the quarter, the company rode sales of electronics and other general merchandise for its biggest revenue gains. North American merchandise sales hit $6.1 billion, up 28 percent from the year ago period, while international merchandise sales climbed 28 percent to $4.1 billion.
Meanwhile media sales -- digital downloads, software, video games and the like -- climbed 14 percent in North America to $2.5 billion. International media sales climbed 1 percent to $2.5 billion.
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.
