anchors的意思 anchors _「秒懂生活」

anchor做名词解释有一个意思叫"电视新闻节目主持人" 请问这是怎么来的?(朗文的解释,还是个AMe-美国英语)是的，
"news anchor"或"anchorperson"，传统上由"anchorman"开始，随着女新闻主播的增加，有了中性得"anchorperson" 。就像"chairman"，现在因有很多"chairwoman"，范指时用中性的"chairperson" 。
A news anchor is a television personality who presents material prepared for a news program and at times must improvise commentary for live presentation. The term is primarily used in the United States and Canada. Many news anchors are also involved in writing and/or editing the news for their programs. Sometimes news anchors interview guests and moderate panels or discussions. Some provide commentary for the audience during parades and other events.
The term anchor (sometimes anchorperson, anchorman, or anchorwoman) was coined by CBS News producer Don Hewitt. CBS cites its first usage as being on July 7, 1952 to describe Walter Cronkite's role at the Democratic and Republican National Conventions. According to Hewitt, the term was in reference to the "anchor leg" of a relay race.
