From Muppet Wiki

Broadway is the name given to the main theater district in New York City. Comprising 39 professional theaters located on and near the street Broadway, it is considered the center of American theater. Its British counterpart is the "West End" theatre district in London. Its roots lie in musical theater, but plays and shows of all descriptions have been staged there.

Films, musicals, songs and plays frequently portray it as the dream of young would-be theater stars to be successful on Broadway. "Broadway" is also frequently used to indicate a style of song, production number or musical play suitable for use on Broadway.
