The Danish American Football Federation (DAFF; Danish: Dansk Amerikansk Fodbold Forbund) is an American football organization in Denmark founded in 1988.
Since 2000, DAFF has seen a huge increase in membership, influenced by Danish television station TV2 Zulu broadcasts of National Football League (NFL) games on Sunday evenings.
The sudden popularity of the sport in Denmark has been dubbed "the Zulu effect" after the name of the TV station.
The popularity of American football in Denmark can also be attributed to the nation's interest in the long career of Danish placekicker Morten Andersen, the NFL's all-time leader in points.
