Question: IN what year were Donald Duck's three nephews introduced? Passage 1:Donald Duck rose to fame with his comedic roles in animated cartoons.

In the 1930s, he typically appeared as part of a comic trio with Mickey and Goofy and was given his own film series in 1937 starting with Don Donald. These films introduced Donald's love interest Daisy Duck and often included his three nephews Huey, Dewey, and Louie. After the 1956 film Chips Ahoy, Donald appeared primarily in educational films before eventually returning to theatrical animation in Mickey's Christmas Carol (1983). His most recent appearance in a theatrical film was 1999's Fantasia 2000. Donald has also appeared in direct-to-video features such as  (2004), television series such as Mickey Mouse Clubhouse (2006–2016), and video games such as QuackShot (1991).
