Sony also suffered production disruptions from the flooding in Thailand. Quarterly sales inched up 1.2 percent on-year to $20 billion. Annual sales plunged nearly 10 percent to $81 billion, as unit sales slipped in flat-panel TVs, video and digital cameras, game machines and personal computers. Sony has bled money for eight straight years in its core TV business, bashed by competition from Samsung Electronics Co. of South Korea and other Asian rivals. And consumers are flocking to products from Apple Inc. like the iPhone and iPad instead of Sony gadgets. A soaring yen that erodes the overseas earnings of Japanese exporters like Sony has also added to the damage.
