US Debt Too Big for National Debt Clock
The US government's debts have ballooned so badly the National Debt Clock in New York has run out of digits to record the spiralling figure.
The digital counter marks the national debt level, but when that passed the $10 trillion point last month, the sign could not display the full amount.
The board was erected to highlight the $2.7 trillion level of debt in 1989.
The clock's owners say two more zeros will be added, allowing the clock to record a quadrillion dollars of debt.
