"A recent Gartner study on e-learning reported that "training is moving online for the same reason that companies attempted outsourcing 10 years ago: not because it is better, but because it is cheaper and more measurable." E-learning has always had the lure of cost savings, but recent events have made any technology that helps avoid travel all the more attractive. Gartner analysts project that the global market for e-learning will grow from $2.1 billion this year to $33.6 billion in 2005 - about a 100 percent compound annual growth rate. And e-learning experts' phones are ringing off the hook."
