Newscasters and Newsreaders
A newscaster (short for "news broadcaster") is a presenter of news bulletins. This person may be working in the field of broadcast journalism as a journalist and electronic news gathering (ENG) as well as a participant in compiling the script with a television producer to be delivered in a news bulletin.
Prior to the television era, radio-news broadcasts often mixed news with opinion and each presenter strove for a distinctive style. These presenters were referred to as commentators. The last major figure to present commentary in a news broadcast format in the US was Paul Harvey. Today, commentary is generally presented in the longer-form talk show format. The term "newscaster" came into common use to distinguish presenters of straight news broadcasts from commentators.
In Britain, ITN's news presenters (especially those on ITV News) are referred to as newscasters (and have been since the 1950s), whilst those working at the BBC are called newsreaders.
