The box office is a metric used to measure the financial success of a movie. It includes money made from ticket sales, online streaming, and other sources. By tracking box office success, studios and producers can make informed decisions about which movies to greenlight and which to avoid. Box office success also has an impact on a movie's critical reception, as a film with a strong box office performance is often seen as more successful than one with a weaker performance. Box office earnings are also used to gauge the overall popularity of a film, as well as to determine what kind of marketing campaigns should be pursued. Ultimately, the box office is a key indicator of a movie's financial success.
