Sony's latest quarterly earnings report has revealed that the company has sold approximately 22.7 million PS3 consoles and 189.7 million games worldwide since its launch in 2006.

Across all divisions, Sony has suffered a net loss of $390.5 million in the first quarter and sales of the PS3 and PSP have plummeted compared to last year's figures. Sony has confirmed that it has sold 1.1 million PlayStation 3s and 1.3 million PlayStation Portables in the first quarter of 2009, compared with 1.6 million PS3s and 3.7 million PSPs this time last year.

The drop in sales has been blamed on the worldwide recession and the strength of the Yen, however analysts believe that the launch of a new PSP in October (PSP Go!) and rumours that a PS3 Slim is on its way haven't helped sales.

Despite a slump in the last quarter, Sony can judge its performance by looking at its competitor's figures. The Xbox 360, which launched a year earlier than PS3, has sold approximately 30 million units worldwide to date (May figures,) showing that the gap between sales of Sony and Microsoft consoles is narrowing.
