TOKYO (Reuters) - Japan's Sony Corp said it is enjoying robust demand for its PlayStation 3 game console and other electronic products so far in this holiday shopping season in the key US market.

"We saw a very positive sales increase for televisions, computers and PS3 in particular," Sony chief executive Howard Stringer told a group of reporters on yesterday.

"I don't think there were any negatives, but we need a little more time to find out how big it was."

Year-end sales are critical for Sony and other consumer electronics makers as they represent a big chunk of their annual revenues.

Sony, which pioneered the mobile music market 30 years ago with its Walkman and once ruled the global television industry in the era of box TVs, has been struggling to keep pace with nimbler South Korean rivals and innovative US IT firms in recent years.
