"Futurama" was originally created as four seasons; Fox broadcast it out of the intended order as five seasons. This list is in production order for the first four seasons on Fox, primarily because this is the order used on the DVDs, as intended by the artists, and it helps avoid plot inconsistencies. A list of Futurama episodes by broadcast order is available in a separate article. The production code is the code used by Fox to indicate the production order of the episodes, and is in the format #ACV##. The first number represents the production season. ACV is Fox's series code for "Futurama". The second number is the episode's number. The TV broadcast code indicates the broadcast order. It is in the format S##E##, where S## indicates the broadcasting season of which there were 5, and E## indicates the episode's number. Seasons currently airing or in production are ordered by broadcast date as the DVD order is unknown, when the DVDs are released the order will be adjusted to represent the final order in case episodes have been aired out of the intended order as they did on Fox.
