comprised a few farms. In 1836, Mayor Cornelius Lawrence opened 42nd Street and invited Manhattanites to "enjoy the pure clean air." Close to 60 years later, theatrical entrepreneur Oscar Hammerstein I built the iconic Victoria Theater on West 42nd Street. Broadway's first "long-run" musical was a 50-performance hit called The Elves in 1857. In 1870, the heart of Broadway was in Union Square, and by the end of the century, many theatres were near Madison Square. Theatres arrived in the Times Square area in the early 1900s, and the Broadway theatres consolidated there after a large number were built around the square in the 1920s and 1930s. New York runs continued to lag far behind those in London, but Laura Keene's "musical burletta" The Seven Sisters (1860) shattered previous New York records with a run of 253 performances. It was at a performance by Keene's troupe of Our American Cousin in Washington, D.C. that Abraham Lincoln was shot. The first theatre piece that conforms to the modern conception of a musical, adding dance and original music that helped to tell the story, is considered to be The Black Crook, which premiered in New York on September 12, 1866. The production was five-and-a-half hours long, but despite its length, it ran for a record-breaking 474 performances. The same year, The Black Domino/Between You, Me and the Post was the first show to call itself a "musical comedy".

They starred high-quality professional singers (Lillian Russell, Vivienne Segal, and Fay Templeton), instead of the amateurs, often sex workers, who had starred in earlier musical forms. As transportation improved, poverty in New York diminished, and street lighting made for safer travel at night, the number of potential patrons for the growing number of theatres increased enormously.
