9.Just look at their counterparts in other countries, they would say. For survival and success, the media out there would balk at nothing and resort to everything, with products representing a wide spectrum of contents and styles, ranging from the radical red through the sensational yellow and undefinable grey down to the dubious black. Our domestic media, they lament, just pale by comparison.
