New Delhi, Aug. 12 -- The 133-year-old photography giant Kodak is fighting for survival. On Tuesday, the company shocked investors by admitting there's "substantial doubt" it can stay in business.

Kodak doesn't have enough money to pay $500 million in debts due within the next year . The warning sent its stock crashing 25% in a single day as panicked investors sold shares . Kodak currently has just $155 million in cash, far less than what it owes.

CEO Jim Continenza tried to calm fears, insisting Kodak is "confident" it can renegotiate its debts.

But the grim announcement marks another crisis for the company that brought photography to millions of families worldwide with its iconic Brownie cameras and yellow film boxes.
