Twelve months ago, Sony was busy recalculating the losses it was expecting to report, due to its beleaguered mobile division. Today, the firm's announcing a 33.6-billion yen ($278-million) profit thanks (once more) to PlayStation and its image sensor division. Overall revenues came in slightly lower than a year ago (down by 0.5%), but a general uptick across the company's many divisions has helped push it into profitability. Despite this, mobile sales continue to slide (down 15-percent this quarter). Sony's Xperia brand is an expensive pastime, costing the company approximately $1.9 million per day in losses.
