Shares in Sony have tumbled below the 1,000 yen (£8.30) mark for the first time since 1980, after years of decline at the Japanese firm.
PlayStation console maker Sony, which last night held its press conference at the E3 Expo in Los Angeles, has struggled to turn around its beleaguered TV business, resulting in four years of consecutive annual losses.
The company also failed to keep pace with Apple and Samsung in the mobile devices market, and has seen Microsoft's Xbox eat into its share of video games hardware sales.
The lack of investor confidence in the firm has caused the share price to fall below 1,000 yen for the first time since August 1980, the year after it launched the hugely successful Walkman portable cassette player.
Sony shares dropped to 990 yen (£8.25) on the Tokyo market before recovering slightly on Monday. But this was a far cry from the peak in the share price, at 16,950 yen (£140.17) in March 2000.
The fall coincided with broader woes across the Tokyo stock exchange, as concerns over jobs growth in America, the Eurozone crisis and the slowing Chinese economy led the market to slump to its lowest level in 28 years.
Last month, Sony reported a record annual loss of $5.7 billion (£3.7bn), after PlayStation 3 sales fell from 14.3 million to 13.9 million units over the 12 months.
