This document discusses the sustainability of Massive Open Online Courses (MOOCs). It notes that while MOOCs aim to be openly accessible, their production costs are high, ranging from $39,000 to $325,000 per course. As such, university and MOOC platform leaders have announced plans to offer some courses with fees to help cover costs. The document predicts that in the future, European universities will no longer be able to afford offering free MOOCs and professional education courses may become an important revenue source, creating a gap between MOOC platforms and universities. It raises open educational resources using Creative Commons licenses as a sustainable alternative business model.
