List of fastest-grossing films
The success of a film is assessed by trade publications (such as Box Office Mojo and Variety) primarily by its theatrical box office earnings. Although several other revenue streams also generate revenue (such as theatrical exhibition, home video, television broadcast rights and merchandising), theatrical box office earnings take prominence, mostly because of the availability of the data compared to sales figures for home video and broadcast rights, but also because of historical practice.
