Sony's PS4 business keeps getting better and better

For the quarter ended June 30, 2015, Sony's game business leapt 12.1 percent in revenues year-on-year, to 288.6 billion yen ($2.33 billion). The division saw profits of 19.5 billion yen ($157 million), a massive 350 percent leap year-on-year.

For the full year, the company has bumped up its expectations for the segment 8.8 percent since its last earnings report in April, showing that the PlayStation 4 is in rude health, even as PlayStation 3 software and hardware sales slide.

Software and peripheral sales for the PS4 boosted the game business in particular, the company said. It was also able to reduce the costs of manufacturing the PlayStation 4.

The company was overall more successful this quarter, with profits jumping to 96.9 billion yen ($780.8 million). Most of that boost came from sales of image sensors, which the company supplies to smartphone manufacturers such as Apple.

The company's mobile division, on the other hand, is slumping -- sales of its handsets decreased 16.3 percent year-on-year. Its film division also suffered.
