The results were slightly better than the average forecast of four analysts surveyed by Bloomberg News. Sales rose to 1.65 trillion yen ($15.38 billion) from 1.48 trillion yen ($13.8 billion).Sony is being challenged by rivals such as Microsoft, which is set to threaten its dominance of the video game console market, and a stronger yen, which depresses revenue earned abroad.
