从中央电视台到各地方电视台,均有一批优秀的电视栏目始终保持着较为持久的生命力。在经过不断的创新、充实后,这些栏目的个性更加鲜明,生命力愈加旺盛。另有一些栏目却在开播并不长的时间里出现颓势。业内习惯把这种现象断定为“栏目的生命周期太短”。 From CCTV to local television stations, there are a number of excellent television programs that have always maintained a more enduring vitality. After constant innovation and enrichment, these columns are more distinctive and more vigorous. In addition, some sections have been on the decline for a long period of time. The industry used to judge this phenomenon as “column life cycle is too short.”
