The Nasdaq MarketSite (or simply MarketSite) is the commercial marketing presence of the Nasdaq stock exchange. Located at Times Square in the Midtown Manhattan neighborhood of 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 28,500-square-foot (2,650 m2) 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.[1]
