"E-learning as we know it has been around for ten years or so. During that time, it has emerged from being a radical idea---the effectiveness of which was yet to be proven---to something that is widely regarded as mainstream. It's the core to numerous business plans and a service offered by most colleges and universities. And now, e-learning is evolving with the World Wide Web as a whole and it's changing to a degree significant enough to warrant a new name: E-learning 2.0."
