Communication mix is changing
no longer can the traditional grouping of promotional tools be assumed to be most effective forms of communication. This brief outline of elements of the promotions mix signals some key characteristics: extent to which every element is controllable; whether it is paid for by the sponsor; and whether communication is by mass medium or undertaken personally. One extra characteristic concerns the receiver's perception of the credibility of source of the message. If credibility factor is high, then there is a greater likelihood that messages from that source would be accepted by the receivers.
