Paramount Pictures

Paramount Pictures is a movie studio based in Hollywood, California, and owned by Viacom, the same company that owns Nickelodeon.

Due to this cross-ownership, the studio is the home video licensee for Winx Club in countries where Nickelodeon owns the rights.

Overview
Paramount was founded in 1912 as Famous Players Film Company, and after numerous other corporate changes over the years, has been owned by Viacom since 1994.

From 2006 to 2008, Paramount had a second mainstream subsidiary, DreamWorks (previously and now once again an independent company), that provided additional movies for Paramount to release. As a by-product of this deal, Paramount was once the distributor for DreamWorks Animation films as well, and from 2008-11, released most Marvel Studios product too.

Paramount became involved in the Winx Club franchise upon Nickelodeon's acquisition of rights for the US, Canada, and select other territories, acting as the home video distributor for the series in those areas, as it does for other properties owned by Viacom Media Networks (like fellow former 4Kids property Teenage Mutant Ninja Turtles.)

Coincidentally, in 2004, Paramount released a film titled Mean Girls, also part of the name of a song from the 4Kids dub of Winx Club.
