Which of these theaters doesn't belong in the category of Broadway theaters?

The Beacon Theatre is not categorized as a Broadway theater. Broadway theaters are a specific group that generally includes theaters located in the Theater District of Manhattan, known for hosting large-scale productions and musicals that require significant financial backing and professional productions. The Beacon Theatre, while an iconic venue located on the Upper West Side and used for concerts and live performances, does not meet the criteria of being a Broadway theater as it is not located in the recognized Broadway district and primarily hosts a different type of entertainment, such as music events rather than theatrical productions.

In contrast, the other options, such as the Hilton, Music Box, and St. James theaters, are all situated within the Broadway area and are officially recognized as Broadway theaters. They host renowned Broadway shows and contribute to the vibrant theater scene in New York City. Understanding the distinction between these types of venues helps clarify the characteristics that define Broadway theaters, highlighting their role in the larger context of NYC's performing arts landscape.
