(Reuters) – AOL Inc reported a rise in first-quarter revenue on Wednesday, boosted by a surge in advertising sales through its automated electronic exchange, but profit fell. Shares of AOL dropped 12 percent to $38.62 as the company reported adjusted earnings per share of 34 cents. The result missed analysts estimates of 45 cents, according to analysts polled by Thomson Reuters. The digital media and entertainment company said revenue from ads bought and sold on its electronic exchange soared 55 percent to almost $187 million.
