Gamasutra's Matt Matthews points out that in terms of revenue, 2009 is one of the worst years for the company. Whereas Sony was able to generate $6.4 billion in revenue from its family of PlayStation products in 2008, the company was only able to rake in $5.1 billion in 2009 -- that's a drop of $1.3 billion, or 20 percent.
While Microsoft and Nintendo also shed some revenue in the difficult economic climate, their losses seem insignificant in comparison: about $200 million each. Matthews notes that a large portion of Sony's lost revenue in 2009 comes from sagging sales of its decade-old PS2 platform. The (understandable) lack of software sales on the PS2 resulted in the loss of approximately $700 million in revenue, while hardware sales have contracted another $150 million.
The PSP also had a difficult year, and it appears the PSP Go hasn't turned around Sony's fortunes. According to Gamasutra's analysis, hardware and software sales on Sony's handheld shrank by about $425 million in 2009. With the demise of the PS2, and the languishing state of the PSP, Sony's former dominance of the market seems but a memory.
