A quick reminder. We don't need another marketing prefix.
Marketing is strategic. It's a combination of elements that creates the environment in which it is possible to meet a customer need (starting right back at product development).
If there's a prefix, it's indicative of a tactical subset of marketing and not of a new paradigm. Promotion/advertising is a subset of marketing, albeit the one that is most often referred to as "marketing" by people who don't know better. So is viral marketing. So is direct marketing.
If one of those tactics is discredited, that's all that has happened. There's no need to create a new prefix. Unless of course, you've got a book or presentation to flog. Here endeth the lesson.
