Video: two interesting case studies

Here are a couple of really interesting case studies demonstrating how effective video can be to communicate a message, engage an audience and deliver commercial benefit.  The first is the story of how TED used video to change its business from an elite gathering to an open media channel consumed by millions and eventually selling its events out faster at a higher price. Read how they did it.

The second piece outlines the 12 lessons learned while marketing 'The 4-Hour Body'.  The promotional video  worked amazingly well, achieving just over 1,200 Amazon reviews in just 5 months, without a book tour or email drip campaigns.
