News broadcasting is the medium of broadcasting various news events and other information via television, radio, or the internet in the field of broadcast journalism. The content is usually either produced locally in a radio studio or television studio newsroom, or by a broadcast network. A news broadcast may include material such as sports coverage, weather forecasts, traffic reports, political commentary, expert opinions, editorial content, and other material that the broadcaster feels is relevant to their audience. An individual news program is typically reported in a series of individual stories that are presented by one or more anchors. A frequent inclusion is live or recorded interviews by field reporters.

👉 Newscast in the context of News magazine
A news magazine is a typed, printed, and published magazine, radio, or television program, usually published weekly, consisting of articles about current events. News magazines generally discuss stories in greater depth than newspapers or newscasts do, and aim to give the consumer an understanding of the important events beyond the basic facts.

Newscast in the context of News producer
The news producer takes all the elements of a newscast (packages, video, graphics, etc.) and compiles them into a cohesive show.
In the hierarchy of the newsroom, the news producer is under the executive producer, who reports to the news director. The news producer is usually on the same level as the anchor, although this may differ from newsroom to newsroom. The news producer is over the director, studio crew, reporters, field crew, photographers, editors, etc.
Newscast in the context of Chroma key
Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two or more images or video streams together based on colour hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video — particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as colour keying, colour separation overlay (CSO; primarily by the BBC), or by various terms for specific colour-related variants such as green screen or blue screen; chroma keying can be done with backgrounds of any colour that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from any human skin colour. No part of the subject being filmed or photographed may duplicate the colour used as the backing, or the part may be erroneously identified as part of the backing.
It is commonly used for live weather forecast broadcasts in which a news presenter is seen standing in front of a CGI map instead of a large blue or green background. Chroma keying is also common in the entertainment industry for visual effects in movies and video games. Rotoscopy may instead be carried out on subjects that are not in front of a green (or blue) screen. Motion tracking can also be used in conjunction with chroma keying, such as to move the background as the subject moves.
