Television news refers to the practice of disseminating current events via the medium of television. News Bulletins are programmes lasting from seconds to hours that provide updates on world, national, regional or local news events. Television channels may provide news bulletins as part of a regular program that is aired daily or more often at standard times. Less often, television shows may be interrupted or replaced by "news flashes" to provide news updates on current events of great importance or sudden events of great importance.
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.
