The Reel Deal
Though they now appear before a movie, they’re called “trailers” because they originally appeared after the film. The first trailer wasn’t even for a movie, but promoted a live musical called “The Pleasure Seekers.”
Originally, a “blockbuster” was a WWII British bomb powerful enough to destroy a city block. Soon after, the term was first adopted to describe a film which grossed revenues of at least $2 million in the US and Canada.
Blockbuster movies often perform well at the “box office.” While the box office is the part of a modern theater which sells tickets to anyone, the term comes from Elizabethan times, when wealthier theater patrons bought tickets to private balcony sections known as “boxes.” Box ticket sales were a good indicator of a play’s financial success, and were sold separately at an office near the theater entrance.
