Warner Brothers has told the University of New Hampshire that it lacked the legal right to use Harry Potter in marketing an online course taught to students entering grades 4 through 8, New Hampshire Public Radio reported. The course -- "Harry Potter as Storytelling: An Online Adventure for the Young Fan" -- teaches grammar and literature. Warner Brothers said that it did not object to a course using Harry Potter books, but to the way the course was described and marketed. The university, while denying any wrongdoing, is changing the name of the course.
