As you can see, the components of the life cycle are unchanged,
but between any two psychographic groups has been
introduced a gap. This symbolizes the dissociation between
the two groups—that is, the difficulty any group will have in
accepting a new product if it is presented in the same way as it
was to the group to its immediate left. Each of these gaps represents
an opportunity for marketing to lose momentum, to
miss the transition to the next segment, thereby never to gain
the promised land of profit-margin leadership in the middle of
the bell curve.
