The holy grail of advertising these days is trying to find exactly what customers are looking for, when they are looking for it and when they are most likely to convert into buyers. In radio and TV advertising, special phone numbers and websites can serve a tracking purpose that allows statisticians to pull out data like this. Online web searching installs a whole new level of data collection that lets sellers really know their buyers (and customize marketing as appropriate). But just how do those customers actually respond to certain forms of advertising? Why are only a fraction of advertising viewers doing anything in reaction to an ad -- why not all 100%?

Biological experiments that take stock of physiological monitoring are nothing new in the advertising arena, and at NBC, advertisers want to know more about consumer reactions as the television medium continues to be under assault from ad dollars moving online (along with advertisers themselves). In order to bring ads back to television, the medium has to evolve beyond passive and impressions-based advertising to one of actually engaging customers and measuring the experience. But what makes up such an experience? Watching KFC (NYSE: YUM)'s absurd ads with a bastardized version of Lynyrd Skynyrd's "Sweet Home Alabama" being screamed in the background, I think, actually drives customers away from the fast-food chain. Perhaps I am wrong.

NBC's research, though, has a new twist: It measures customer engagement to commercial advertisements viewed in fast-forward mode. With more folks in the U.S. using TiVo and other digital video recorders that allow fast-forwarding through commercials, TV networks are losing ad dollars to advertisers that don't want to pay for viewers that zap right through commercials. But, if those viewers have some kind of meaningful engagement to the commercial, even when fast forwarded, then the networks regain some ammunition to negotiate ad rates.
