Notable signage includes the Toshiba billboard directly under the NYE ball drop, the curved seven-story NASDAQ sign at the NASDAQ MarketSite at 4 Times Square on 43rd Street, and the curved Coca-Cola sign located underneath another large LED display owned and operated by Samsung. Both the Coca-Cola sign and Samsung LED displays were built by LED display manufacturer Daktronics. Times Square's first environmentally friendly billboard powered by wind and solar energy was first lit on December 4, 2008. On completion, the 20 Times Square development will host the largest LED signage in Times Square at 18,000 square feet. The display will be 1,000 square feet larger than the Times Square Walgreens display and one of the largest video-capable screens in the world.
