Google reported a small increase in profits Thursday below market expectations, but a strong rise in revenues lifted its stock price. Google had a great quarter with revenue up 22 percent year on year, at $16.0 billion, chief executive officer Patrick Pichette said in an earnings release. Google shares rose 1.5 percent to $582.35 in after-market trading that followed release of the earnings figures. The company also said that one of its key executives, chief business officer Nikesh Arora, would be leaving Google after nearly 10 years to take a job at Japans SoftBank.
