Link to this article describes some of the considerations for distance education and applications to development of Massively Open Online Courses (MOOC's) - http://www.dlib.org/dlib/july13/fowler/07fowler.print.html. Discussion from Duke University experience with Coursera and the Coursera copyright guidelines. "...content from popular culture is integral to the instruction for specific courses, for example, for a line-by-line rhetorical analysis of a newspaper editorial or to highlight video processing mistakes in a high-grossing Hollywood film. Therefore, Duke's guidelines do not prohibit instructors from using designated types of content. We do ask them, however, to consider carefully if the specific material is essential to the pedagogy of the course, or if a public domain or Creative Commons-licensed alternative might serve their purposes equally well."
