Sony Corp. on Tuesday reported a record first-quarter operating profit on the back of strong sales of game software, giving support to the new management's strategy of focusing on stable sources of revenue.

The electronics firm posted profit of ¥195.0 billion for April-June, up 23.7 percent from ¥157.6 billion a year prior.

With the previous year's one-time gain of ¥36.8 billion excluded, Sony logged even sharper first-quarter growth of 61 percent. That gain came from the sale of Sony's camera module unit and the receipt of insurance payouts for earthquake damage.
