Mobile Ads, Earnings | featured news

Facebook was once a darling of investors, then a turnoff. Now, a year after going public, the social network seems to have settled into a more stable relationship with Wall Street. But the company has still been taking pains to prove that it can make more money from its base of more than a billion users, especially from those using Facebook on mobile devices.

Facebook lost $59 million in the third quarter, but the newly publicly traded social networking site saw its shares soar on Wall Street early Wednesday. Facebook shares gained $4.35, or 22%, to $23.85 in early trading, after the company reported gains from mobile advertising.
