Seth Godin has a brief yet characteristically insightful piece up at his website suggesting why people might prefer the "live" experience to the lasting (and undoubtedly cheaper) experience recorded media provides. For those of you who are unfamiliar with Mr. Godin, shame on you...he's one of the most brilliant marketing philosophers out there, and his books should be mandatory reading for anyone who's serious about delivering an exemplary product to their guests. Your penance is to head to his website straight away, read the article, and pick up any of his fantastic works. Your events will be better for it.
