Sony's Networked Products and Services division, which includes the PlayStation business, recorded an operating profit of 35.6 billion ($435.3m / 266.9m) for the 2010 financial year, up from the 83.3 billion loss for the previous year.

The company highlighted improved software sales for the system, as well as reduced costs on PlayStation 3 hardware for the increase. Sales in the division only increased marginally to 1,572 billion ($19.2 bn / 11.7 bn).

During the year, Sony sold 14.3 million PlayStation 3 units compared to 13 million, 8 million PSPs compared to 9.9 million, and 6.4 million PlayStation 2 consoles, compared to 7.3 million for the 2009 financial year.

Software sales for the PlayStation 3 was up significantly from 115.6 million to 147.9 million, with PSP game sales also up from 44.4 million to 46.6 million. PlayStation 2 game sales dropped from 35.7 million units to 16.4 million.

As warned earlier in the week, the Sony Corporation as a whole made a significant loss during the full financial year of 256.9 billion ($3.14bn / 1.92bn) primarily due to deferred tax assets.

Sales were 7,181 billion ($87.7bn / 53.8bn) for the full financial year, a drop of 0.5 per cent compared to 2009, with operating income of 199.8 billion ($2.4bn / 1.4bn).

The company has warned that in the current fiscal year, it expects the cost of the PSN breach to hit approximately $170 million.
