Nickelodeon is an American children's channel founded in 1977. It is usually simply called Nick and was originally named Pinwheel. It is owned by Viacom, which also purchased minority stake in Rainbow S.r.l. in early 2011, and is aimed at children from 7 to 17 years. As from late 2011 it acquired the airing rights for Winx Club from Rainbow S.r.l. for the majority of English-speaking regions after 4KidsTV lost the airing rights for Winx Club for the American audience.

On September 2, 2010, Nickelodeon announced it had acquired the rights to the animated series Winx Club for broadcast on the flagship American channel and several of its international channels. The channel plans to co-produce the fifth and sixth seasons of the series, and has also gained the rights to air the existing episodes of the TV series and two theatrical films. On June 27, the first of four one-hour specials, created to summarize the first two seasons, aired, with the second set to air on August 1. Season three will air in full when the specials finish, with season four sometime after. Both the specials and the full seasons will feature a new voice cast and a re-vamped animation style, a bit different from the original.
