My point is that personal communication more direct, more specific and can be used to directly to product to sell to specific person, and not only to the public in interpersonal communication did not have a specific person, marketing power was not so strong.

My viewpoint is individual dissemination is more direct, more concrete, may directly the product sales promotion for the concrete person, but the non-interpersonal dissemination is only for the populace, does not have the concrete person, the sales strength not that strong.

My view is more direct personal communication and, more specifically, you can sell directly to the product to a specific person, rather than interpersonal communication to the public, there is no specific person, sales force is not so strong.
