The Nasdaq MarketSite (or simply MarketSite) is the commercial marketing presence of the Nasdaq stock market. Located in Times Square, Midtown Manhattan, New York City, it occupies the northwest corner at the base of the 4 Times Square skyscraper. The exterior wall of the eight-story cylindrical tower includes an LED video display that provides market quotes, financial news, and advertisements. Einhorn Yaffee Prescott designed Nasdaq MarketSite's space inside, which contains two broadcast studios and originally had a second-floor exhibit called the "MarketSite Experience". MarketSite was built in 1999 and debuted on January 1, 2000. Description Exterior Nasdaq MarketSite is located at the northwest corner of 4 Times Square, facing Broadway to the west and 43rd Street to the north, along Times Square in the Midtown Manhattan neighborhood of New York City. It has an eight-story cylindrical facade. At street level is a three-story glass facade. The glass curtain wall was meant to allow clear views of the broadcast studios behind it. Above the studio, the facade consists of a giant LED display, variously cited as measuring or . Measuring high, the display was the world's largest at the time of its completion. The display is allowed because 4 Times Square is exempt from zoning rules regarding signs. The display is made of about 8,200 or 8,400 panels manufactured by Saco Smart Vision. The panels, in turn, are powered by over 800 units behind the screen, which are similar to the size of a shoebox. The LEDs are spaced as closely as apart. With over 18 million LEDs, the display can show information at a computer display standard of 1280x1824. The panels are thick. As designed, the sign was lit every day from 7 a.m. to 1 a.m., displaying advertisements, videos, news broadcasts, and financial and market information. Companies are identified by logos rather than their ticker symbols. The display is interrupted by thirty square windows. The windows are arranged into five rows, which illuminate a portion of Condé Nast's space. The panels are covered with translucent coating, but water seepage from the windows can sometimes damage the display. There is a catwalk and a ventilation space behind the display, which created an effect resembling a tunnel. At 4 Times Square's opening, Nasdaq leased the sign space from the Durst Organization for $2 million a year. Interior Einhorn Yaffee Prescott designed Nasdaq MarketSite's space. The space had a 72-seat auditorium, a
