The Theater District, as its name suggests, is the center of performing arts in New York City. The area centers on the convergence of Broadway with 7th Avenue.
The birth of the Theater District can be traced to the arrival of the Metropolitan Opera House to the intersection between Broadway and 40th Street in 1883. It attracted other theaters and restaurants to open in its vicinity. The neon lights along this stretch of Broadway gave the street the nickname, "Great White Way", making the very name Broadway synonymous with the entertainment industry.

The Theater District lost much of its glitter after World War II, and by the 1970's had become a rather seedy neighborhood. Recent redevelopment projects are aimed at revitalizing the neighborhood and bringing back the general public.
