My old marketing professors would consider my endorsement of this to be on par with blasphemy (BTW, I thought there were only 4 P's of marketing?) Anyway Bill Flitter of Pheedo (a former fellow Wisconsinite!) has some put some meat behind his theory of the changing of the P's. Frankly, I don't know where he comes up with this stuff, but I really did what Pheedo & Bill have to say, and like their takes on this industry...more good stuff to come I imagine.

He goes on to define the new P's here...

Dana, over the years I've added "Positioning" to the P's. You can have the best product but if your copy is missing the target audience or you're missing the right audience in general, your sales will reflect it. I'll make an update to the site so not to confuse. Thanks for pointing that out.
