The Broadway musicals are most likely named for their beginnings as New York productions.

Explanation:

Broadway is the most prestigious form of professional commercial theater in the United States and is also the best known genre of American theater internationally. The term Broadway refers to a theater performance, usually a play or musical, for a large audience, held in one of the approximately 40 halls with 500 or more seats located in the theater district of New York, around the Broadway street in Manhattan. The shows that reach Broadway and do well there are generally more profitable, as they attract more audiences.
