National Debt Clock
The National Debt Clock is a billboard-sized running total dot-matrix display which constantly updates to show the current United States gross national debt and each American family's share of the debt. It is currently installed on Sixth Avenue (Avenue of the Americas) in Manhattan, New York City.
The idea for the clock came from New York real estate developer Seymour Durst, who wanted to highlight the rising national debt. In 1989, he sponsored the installation of the first clock, which was erected on 42nd Street close to Times Square. At the time, the national debt remained under $3 trillion but was rising. The clock was temporarily switched off from 2000 to 2002 due to the debt actually falling during that period.
In 2004, the original clock was dismantled and replaced by the current clock at the new location one block away. In 2008, the U.S. national debt exceeded $10 trillion for the first time, leading to press reports that the clock had run out of digits.
The original clock outlived Seymour, who died in 1995, with Seymour's son Douglas taking over responsibility for the clock through the Durst Organization. As of September 2009, Douglas Durst's cousin Jonathan "Jody" Durst, with whom he currently shares a co-presidency of the company, is in the process of taking over the day-to-day operations as president. In an interview with The New York Times, Jonathan Durst has said that maintenance of the clock is planned "for years to come."
Invented and sponsored by New York real estate developer Seymour Durst, the National Debt Clock was installed in 1989. After Seymour's death in 1995, his son Douglas Durst became president of the Durst Organization which owns and maintains the clock.
Douglas Durst has been quoted as saying that the clock represents a non-partisan effort; he has further explained the motivation behind the project in terms of intergenerational equity: "We're a family business. We think generationally, and we don't want to see the next generation crippled by this burden."
According to Douglas Durst, his father had been toying with the basic idea of drawing attention to the growing national debt since at least 1980, when during the holiday season he sent cards that said "Happy New Year. Your share of the national debt is $35,000" to senators and congressmen. In the early eighties, when Durst first developed the idea of a constantly updated clock, the technology required to implement the project was not yet available.
First clock 
With the national debt at 2.7 trillion dollars, the original 11 by 26 feet (3.4 m × 7.9 m) clock was constructed in 1989 at a cost of $100,000. It was mounted a block from Times Square, on a Durst building at Sixth Avenue near 42nd Street, facing the north side of 42nd Street and Bryant Park across the intersection. Built by the New York sign company Artkraft Strauss, the clock featured a dot-matrix display with the then-typical character resolution of 5x7. Similar to the second clock, the updating mechanism was such that the display was set to the estimated speed of debt growth (odometer-style) and adjusted weekly according to the latest numbers published by the United States Treasury. Up until the week before his death, Seymour Durst himself adjusted the tally via modem. Since his passing, Artkraft Strauss has been keeping the figures current.
In 2000, due to an improving debt situation, the clock started to run backwards. With the original purpose of the clock being to highlight the rising debt and the reverse giving a mixed message, and with the display not being designed to properly run backwards, the clock was unplugged and covered with a red, white and blue curtain in September 2000, with the national debt standing at roughly 5.7 trillion dollars. The clock was not dismantled however, and in July 2002 the curtain was raised and the clock once again picked up tracking a rising debt, starting at 6.1 trillion dollars.
Second clock 
In 2004, the original clock was moved from its location near 42nd Street; the building has since made way for One Bryant Park. An updated model, which can run backwards, was installed one block away on a Durst building at 1133 Avenue of the Americas (Sixth Avenue). It is mounted on the side wall of the building which faces W. 44th Street. The new clock is outfitted with a dot-matrix display of higher resolution than its predecessor which emulates the customary seven-segment numeral patterns, allowing the numbers to be read more easily.
In the midst of extensive media attention during the financial crisis beginning in 2007, some news reports mentioned the National Debt Clock, highlighting the fact that its display had run out of digits when the U.S. gross federal debt rose above $10 trillion on September 30, 2008.
Similar projects 
The idea of conveying a message through a periodically updated clock found an earlier expression in the Doomsday Clock. However, the innovation of the National Debt Clock was to feature a constantly running counter; it has since inspired similar projects elsewhere, both in the United States and further afield. Various tracking counters of national debt are also kept online.
The National Debt Clock has also been credited as the inspiration behind other running totalisers, for example an AMD campaign employing an electronic billboard; instead of a debt, it tracked the supposed additional cost of using a rival chip.
