A lot has changed in the past few years. If you need a crash course in educational videos and statistics about the evolution of communication using social media: the following five videos are guaranteed to have at least a few facts and concepts that make you think.

I recommend sitting down and watching all of these from top to bottom, as three of the videos are part of a series (Do You Know 2.0, 3.0, 4.0) that came from 2007. While the information is old, the reality of trends in 2007 is now a historical footnote for 2010. As we see adoption take root with several technologies moving through 2012/13, some of these videos will find themselves into world economics and business fundamentals training.

If you know of any other suitable videos that have this many metrics packed into a few minutes, please leave a link below.
