Started in 2002 and completed in 2004, the tower contains Class A office space. Some of the most prominent features of the Times Square Tower are its billboards, several of which hang on the building's façade. Most of the large signs are found near the base, but one 4-story sign is found above the middle of the building. Towards the end of 2011, an electronic billboard replaced the static billboard towards the top of the tower. The building is also known for the zig-zag patterns on its exterior.
