20世纪末，电视媒体在网络等新兴媒体的冲击和社会转型的影响下，遭遇了观众分流和公信
力下降的现实危机。在新的媒介环境下，电视媒体选择了主动改变自身并积极与新兴媒体展开合
作。在此过程中，我国电视新闻在与新兴媒体的融合和合作中悄然发生了改变，它不仅重新确立
了直播日常化的基本理念，还将文本引入了一个相对开放的叙事时空。在本文中，笔者不仅对电
视媒体在新媒体环境下面临的三重挑战予以了分析，还在此基础上着重阐述了电视新闻在新媒体
环境下发生的几重转变：直播美学的重新确立、生产平台的战略调整、受众地位的历史转变。

In the end of the 20th century, TV media were in face of the crisis of audience split-flow and loyalty
decline, as a result of the impact of social transformation and emerging media like internet. In the new
medium environment, TV media chose to take the initiative to change themselves and set up cooperation
with emerging media positively. During this process, TV news came into changes gradually in the
coordination with emerging media in our country, which didn’t only re-establish the basic idea of Live
Telecast Dailization, but lead text into a relatively open narrative time and space. In this thesis, the author
is not only to analyze the three challenges, but also to expound based on them several changes of TV
news in the new medium environment: re-establishment of live telecast aesthetics, strategic adjustment of
production platform, historical transformation of audience position.
