A newscast typically consists of the coverage of various news events and other information, either produced locally by a radio or television station newsroom, or by a broadcast network. It may also include such additional material as sports coverage, weather forecasts, traffic reports, commentary and other material that the broadcaster feels is relevant to their audience.
In some parts of the world there are 'rolling news' TV channels that broadcast
news 24 hours a day.
Television news consists of several different elements, introduced by a news
presenter or presenters. The presenters read 'links' and do interviews.
Most news stories come in the form of short 'packages'. These are pre-recorded
reports usually lasting from one to five minutes. News reporters gather and edit together interview clips, pictures and their
own 'pieces to camera' to tell a story. They script and record a 'voice-over' to explain the pictures and link the elements
Some stories are done as live reports. This can be a reporter on the scene
of a story either being interviewed by a studio presenter (sometimes known as a 'two-way'), a reporter interviewing one or
more other people, or simply live pictures and sound of an event. The sound and pictures are sent back to the TV station via
fixed cable links, bounced off a satellite from a vehicle carrying a satellite dish (a 'sat truck'), or sent through microwave radio transmissions from a vehicle carrying a microwave transmitter. With the growth
of "rolling news" channels the use of live material has increased enormously and TV reporters are now often judged as much
on their ability to perform live in front of a camera as on their package-making or writing skills.
TV news programs are put together by producers, who decide what goes in and
what gets left out, and how long and in what form each story is presented. They put together 'running orders' - a list of
the stories in what they decide is the right order.
A separate news editor is often responsible for co-ordinating the gathering
