Issues surrounding advertising standardization tend to parallel issues surrounding product and positioning standardization. On the plus side, economies of scale are achieved, a consistent image can be established across markets, creative talent can be utilized across markets, and good ideas can be transplanted from one market to others. On the down side, cultural differences, peculiar country regulations, and differences in product life cycle stages make this approach difficult. Further, local advertising professionals may resist campaigns imposed from the outside—sometimes with good reasons and sometimes merely to preserve their own creative autonomy.
