Sony sold 1.8 million PS3s in the three months to 30 June, its first financial quarter, compared to 2.4 million in the same quarter last year.

In April hackers accessed the personal data and possibly the credit card records of around 200 million users of Sony's online gaming and entertainment services, PlayStation Network and Qriocity.
