Sony Corp. said Thursday its group net profit fell 25.3 percent in the second quarter to 32.92 billion yen due to large research and development costs in its game division.
Group revenue for the July-September period edged up 0.4 percent to 1.8 trillion yen.
The consumer electronics giant, which has been suffering lackluster performance, said there were signs of a pickup in its electronics business, which accounts for more than two-thirds of the group's total revenue.
