Sony is enjoying a sharp profit spike in its latest quarterly financials, largely driven by its PlayStation business and the blockbuster success of Spider-Man: Brand New Day. According to the company’s September earnings, Sony’s net profits climbed to 449.60 billion yen (about $2.84 billion) for the three months ended September — a 44 percent increase compared to the 311.4 billion yen ($1.96 billion) it reported for the same period last year.
