Google’s second-quarter earnings rose by a better-than-expected 19 percent on the Internet giant’s ability to manage costs, but revenue growth slowed, indicating that advertising conditions remain challenging, according to Dow Jones Newswires. For the quarter ended 30 June, Google reported earnings of US$1.48 billion, or US$4.66 a share, compared with US$1.25 billion, or US$3.92 a share, a year ago. Revenue rose 2.9 percent to US$5.52 billion.
