When Professor Clayton Christensen introduced the concept of disruptive innovation, he referred to it as the one produced with goods or services that, originally born as something almost residual, quickly become leader in their field. Well, according to this definition, MOOCs (Massive Open Online Course), as Lluís Anglada has already stated, are a clear example of disruption for several reasons: because of their cost, because they are based on new insights into the psychology of learning, and because they are adapted to the new social needs towards education.
