Sony's games division was a key contributor to an improved set of financial results for the company's first quarter ended June 30.
The firm's Game & Network Services unit generated sales of 257.5 billion yen (£1.5b/$2.5b), up 95.7 per cent year-on-year, primarily due to PS4's strong performance.

Combined PS4 and PS3 sales totalled 3.5 million units in the first quarter, up from 1.1 million in the same period a year ago, but down slightly from 3.7 million in the prior quarter ended March 31.
Vita and PSP sales came in at 750,000 units, compared to 600,000 a year ago and 700,000 in the prior quarter.
Software sales for all platforms hit 85 million, compared to 68 million a year earlier and 93 million in the prior quarter.
As a whole, the wider company's sales totalled 1,809.9 billion yen (£10.4b/$17.6b), an increase of 5.8 per cent year-over-year.
The firm made a net profit of 26.8 billion yen (£151m/$261m), up from 3.1 billion yen a year ago.
