TV Rating by means of meter systems exercises a strong influence over TV programming in Japan. But the systems have structural errors unique to this panel-rotation survey method. The entire sample consequently becomes distorted either toward the side of large families or toward the side of elderly families both of which are heavier TV viewers. The TV Rating principle is inconsistent with the diversity principle of TV programmes in society. An appearance of many pay channels by digital satellite may decrease the influence of TV Ratings.
