Sony second-quarter profits plunge 72%

TOKYO -- Sony's second-quarter profits have plunged 72% with a surging yen wiping out the benefits of solid flat-panel TV and PlayStation 3 game machine sales.

The Japanese electronics and entertainment company reported Wednesday net profit of $214 million for the period from July through September, down 71.8% from the previous year.

Revenue from Sony's hit movie Hancock wasn't enough to offset the hammering the maker of the Walkman portable player is taking from the strong yen.

A rising yen erodes the value of overseas profits for Japanese exporters like Sony.
