Know anything about Marketing and information flows?

I got into a discussion about a formula or algorithm or ??? derived from a marketing practice. The name had something to do with info flows, but the basic concept was along the lines of X advertisements will return $Y to a company.

Anyone want to fill me in further or have any clue what I’m talking about?

Thanks-

{bump} before I leave for the day…

One last bump and then I give up and go cry in a corner…OK, not really, but still…

I have an MBA but that’s not anything I recall hearing about in school. I graduated in 1984 so it might be a newer idea. Maybe someone in the adverstising field can help you out.
