The news media or news industry are those elements of the mass media that focus on delivering news to the general public or a target public. These include print media (newspapers, newsmagazines), broadcast news (radio and television), and more recently the Internet (online newspapers, news blogs, etc.).
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 worldwide, while a public address system in (for example) a workplace may broadcast very limited ad hoc soundbites to a small population within its range.
