Hulu has added Nickelodeon shows to the Hulu Plus online subscription service. That means shows like “iCarly,” “Nick Stars,” and “Supah Ninjas” will be available to watch any time, including episodes from the current season (an exclusive for Hulu). Hulu says they will also remove the advertising from current Nickelodeon shows 21 days after airing for the first time. Additional shows now available for Hulu Plus subscribers include “SpongeBob SquarePants,” “Kung Fu Panda,” “The Penguins of Madagascar,” “Winx Club,” and “Robot & Monster” among others.
