A play is a form of dramatic art in which spoken word is used to present a story. Plays are performed live by actors on a stage.
So, the main difference between a Broadway show and a play is the location in which it is performed. Broadway shows are performed in specific theatres in New York City, while plays can be performed in any theatre anywhere in the world. Additionally, Broadway shows tend to be larger and more elaborate productions than plays, with more actors, sets, and costumes. However, there are many exceptions to these rules, and some plays may be just as large and elaborate as Broadway shows. Ultimately, the best way to determine whether a particular production is a Broadway show or a play is to consult the theatre's website or box office.
