20世纪八九十年代以来 ,传播公司的兼并浪潮此起彼伏 ,三大传播公司相继被收购兼并。本文认为这种媒体高度集中或垄断造成的新闻价值的削弱 ,新闻目标的偏离 ,无论对新闻从业者、受众还是国家而言都是灾难性的 ,因此必须采取必要的措施防范新闻垄断。 Since the eighties and nineties of the 20th century, mergers and acquisitions of communications companies have taken off one after another. The three major communications companies have been merged and acquired one after another. This paper argues that the weakening of the news value caused by the high concentration or monopoly of such a media and the deviation of the news target are catastrophic for news practitioners, audiences and countries. Therefore, necessary measures must be taken to prevent news monopoly.
