Sony said it aimed to double its revenues from the fast-growing markets of Brazil, Russia, India and China to $AUD19.7 billion and also invest $AUD 18 billion in key businesses and technologies as part of this three-year growth strategy, according to a report in Reuters.

This follows three years of painful restructuring whereby the company has reduced its global workforce by 10,000 and closed 11 factories in an attempt to return to profitability.

This strategy seems to have paid off as Sony's revenue has risen 23 per cent and operating income 157 per cent during that same period.

Part of this strategy was seen earlier this year when Sony announced it was doubling its annual production of Bravia LCD TVs in Slovakia from two million in fiscal 2007 to four million by the end of this calendar year, making the Slovak factory Sony's largest producer of LCD TVs.

The Japanese maker of PlayStation electronic games and Bravia flat TVs trails Samsung Electronics in the global LCD TV market, and is also locked in a three-way battle with Microsoft and Nintendo for control of the gaming market.

Furthermore, the company said it also aims to turn each of its three key businesses of Vaio PCs, Blu-ray disc-related products, and microchips and electronic components across all geographic locations into operations worth some one trillion yen in three years.
