The news media refers to the section of the mass media that focuses on presenting current news to the public. These include print media (newspapers, magazines); broadcast media (radio stations, television stations, television networks), and increasingly Internet-based media (World Wide Web pages, weblogs).
The term news trade refers to the concept of the news media as a business separate from, but integrally connected to, the profession of journalism.
A medium (plural media) is a carrier of something. Common things carried by media include information, art, or physical objects. A medium may provide transmission or storage of information or both.
The industries which produce news and entertainment content for the mass media are often called "the media" (in much the same way the newspaper industry is called "the press"). In the late 20th century it became commonplace for this usage to be construed as singular ("The media is...") rather than as the traditional plural.
Broadcasting is the distribution of audio and video signals (programs) to a number of recipients ("listeners" or "viewers") that belong to a large group. This group may be the public in general, or a relatively large audience within the public. Thus, an Internet channel may distribute text or music world-wide, while a public address system in (for example) a workplace may broadcast very limited ad hoc soundbites to a small population within its range.
The sequencing of content in a broadcast is called a schedule.
Television and radio programs are distributed through radio broadcasting or cable, often both simultaneously. By coding signals and having decoding equipment in homes, the latter also enables subscription-based channels and pay-per-view services.
A broadcasting organization may broadcast several programs at the same time, through several channels (frequencies), for example BBC One and Two. On the other hand, two or more organizations may share a channel and each use it during a fixed part of the day. Digital radio and digital television may also transmit multiplexed programming, with several channels compressed into one ensemble.
When broadcasting is done via the Internet the term webcasting is often used.
Broadcasting forms a very large segment of the mass media.
Broadcasting to a very narrow range of audience is called narrowcasting.
A newsmagazine, sometimes called news magazine, is a usually weekly magazine featuring articles on current events. News magazines generally go a little more in-depth into stories than newspapers, trying to give the reader an understanding of the context surrounding important events, rather than just the facts.
