Blockbuster

we all have heard the word blockbuster, Haven't you? most of the time when a movie releases and the ratings are really high at that time, we say that this/that movie was a blockbuster, but do you know that how did the word came out to the dictionary ? do we know the history of the blockbuster?

During second world war, Britain threw gigantic bombs on Germany; after explosion, those bombs destroyed the lots of blocks of neighborhood houses. May be in Hollywood they started using the word blockbuster, because when there was a really good movie in theater, other theaters were seemed like empty graveyard. so we can say that the situation becomes same here in terms of destruction of blocks and destruction of audience of other theaters. that is how it started using in Hollywood and nowadays, everybody uses it as a hit performance or good performance.
