A "blockbuster" originally referred to a highly successful film that generates significant box office revenue. These movies often feature big-name actors, high production budgets, and extensive marketing campaigns. The term has since expanded to include any work of art, such as books or video games, that achieves widespread popularity and commercial success. The concept of a blockbuster is closely associated with the entertainment industry, particularly in Hollywood, where films like Avatar and Titanic have set records for ticket sales. Blockbusters often dominate cultural conversations and can influence trends in media and consumer behavior.
