Amazon.com Inc reported a surge in quarterly revenue on Tuesday while profit slipped as the largest Internet retailer benefited from growth in e-commerce but kept spending on distribution, technology and digital content.

Second-quarter net income came in at $191 million, or 41 cents per share, versus $207 million, or 45 cents per share, in the same period a year earlier. Revenue was $9.91 billion, up 51 percent from a year ago.
