Education via the Internet vis-à-vis online lessons have become a lot more common nowadays than they have for the last decade.
I myself have attended many so-called online courses from places such as coursera (which is the umbrella website for lectures and lessons from many solid American Universities such as UCLA and Stanford) and Khan Academy. I've nothing but compliments for them both.
They're not, if you wish, formal courses in the sense that they are no substitute for regular graduation or post-graduation courses from Universities. That doesn't mean that there aren't government-approved fully online University courses.
I think there's nothing more natural than using the Internet to lower costs and spread knowledge for everyone.
Everyone said Wikipedia wouldn't work, but it is a solid example that it's possible and it's useful.
