Medium (bearer)
For other meanings of "medium," see Medium (disambiguation).
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.
By metonymy, 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.
