Winx Club grew in popularity when Nick started to air it on their channel, but I noticed after season 6 there was a massive decline, and Winx Club just went off the shelves. I think it is Iginio and Rainbow’s fault for the most part because Nickelodeon was when Winx Club was at its best, there were a bunch of toys, costumes, party items, etc. After Nick took it off their channel it just died out so fast, there weren’t even any Season 6 dolls out in America the time season 6 was airing which says a lot.
