Nintendo Co.'s market value on Monday surpassed that of Sony Corp., a company with eight times more revenue, underscoring the success of the Wii game console in outselling rival PlayStation 3.
Shares of Nintendo, based in Kyoto, rose to a record 46,350 yen on Monday, valuing the company at 6.57 trillion yen, and overtaking Sony's 6.48 trillion yen capitalization in trading. Nintendo's stock closed 0.8 percent lower at 45,100 yen.
Sony, which overtook Nintendo as the world's biggest console maker after the PlayStation 2 was introduced in 2000, suffered production delays and slow sales of its latest player. Wii's lower price and a wandlike controller that players swing like a sword or tennis racket helped Nintendo widen its sales lead over the PlayStation 3 in Japan last month.
