Winx Club

Winx Club is an animated series produced by Rainbow, with later seasons co-produced by Nickelodeon. It was created and directed by Italian animator Iginio Straffi. It premiered on 28 January 2004, becoming a ratings success in Italy and on Nickelodeon networks internationally. The series is set in a magical universe inhabited by fairies, witches, and other mythical creatures, and tells the story of Bloom, a teenage girl from planet Earth who discovers she is a fairy. Enrolling at Alfea College, she befriends four other fairies and forms a group called the Winx Club, fighting a long series of enemies threatening the Magic Dimension, and in the process, discovering her true origins and the fate of her biological family.

Straffi's original storyline for Winx lasted three seasons, but he chose to continue with a fourth season in 2009. Around this time, Winx Club's popularity attracted the attention of American media company Viacom, who acquired 30% of Rainbow S.p.A. in 2011. Starting in 2010, Rainbow began producing new seasons of Winx Club with Nickelodeon Animation Studio; episodes were jointly written by the Italian and American teams, with Nickelodeon aiming to make the series multicultural and appealing to viewers from different countries. To attract American audiences, Viacom assembled a voice cast that included notable Nickelodeon actors (such as Elizabeth Gillies and Ariana Grande), invested US$100 million in advertising for the series, and inducted Winx Club into the Nicktoons franchise. The continued partnership between Rainbow and Nickelodeon on Winx Club led to the development of more co-productions, including Club 57 in 2019, on which much of Winx Club's staff worked.
