Having had much involvement myself with delivering e-seminars online, I've come to closely track the fast-growing world of online learning (e-learning). It's becoming a huge business, with big publishing companies such as CNet offering
free online courses, and top universities such as U.C. Berkeley offering
free webcasts and podcasts to the public. The United States is the single largest e-learning market worldwide with revenues exceeding $17.5 billion in 2007, according to
a report from Global Industry Analysts. Did you know that one of the biggest players in software and platforms for e-learning is a free, open source offering? If not, meet
Moodle.
