一个地区所拥有的各类电视频道资源是有限的,而一个地区同一级的电视频道拥有者可以自办节目的,则更是有限。如省、市一级的电视台,从无线电视、卫星电视到有线电视,多则十个八个,少则三五个,地市一级就更少了。作为国家级的中央电视台,目前也仅自办了八个频道的节目。 The resources of various types of television channels owned by a region are limited and the number of television channel owners at a same level in a region can run their own programs even more limited. Such as provincial and municipal level television stations, from wireless television, satellite television to cable television, as many as ten eight, ranging from three to five, even less at the prefectural and municipal levels. As a state-run CCTV, it has only run eight channels of programs.
