Sony Corp. said Wednesday it will place more emphasis on flat TVs and DVD recorders and spend 300 billion yen on a massive restructuring drive over the next three years.

The consumer electronics giant has been under pressure to present a convincing growth strategy, with its dismal earnings outlook for the current year having sent its shares tumbling last month.

"We are sorry that 'Sony Shock' has caused various anxieties," Nobuyuki Idei, the firm's group chief executive officer, told a meeting with analysts and the media in Tokyo.
