Amazon reports strong quarter

Amazon.com showed it wasn't being hurt by economic weakness and high fuel prices, reporting Wednesday that its second-quarter profits more than doubled and surpassed analyst expectations. The Internet retailer also raised full-year revenue projections.

Sales were strong in several sections of Amazon's massive marketplace.

For the quarter that ended June 30, Amazon earned $158 million, or 37 cents a share. Amazon earned $78 million, or 19 cents a share, in the same quarter last year.
