Sony Corp. is introducing a smaller, slimmer and lighter version of the PlayStation 3 in time for the holiday shopping season.

The Japanese electronics giant is struggling as its other businesses suffer from competition with Apple Inc.’s iPhone and cheaper Asian rivals. The company is banking on games to help steer a turnaround.

The new PlayStation 3 is half the size of the original model, introduced in 2006. It also offers more hard-drive memory. Prices start at $269 in North America.
