Thomas Nelson CEO/president Michael Hyatt recently convinced roughly one-quarter of the company's Nashville-based employees to take part in a local half-marathon. A few weeks ago, he used his blog to collect staff testimonials about the experience, and now he's hosting a mini-documentary put together by his corporate communications director with some help from Literary Video. It's a good reminder that the power of online video isn't in its capability to promote products, but to promote ideas, whether those ideas are stories (fiction or nonfiction) or identities (personal or collective).
