Media, like data, is the plural form of a word borrowed directly from Latin. The singular, medium, early developed the meaning “an intervening agency, means, or instrument” and was first applied to newspapers two centuries ago. In the 1920s media began to appear as a singular collective noun, sometimes with the plural medias. This singular use is now common in the fields of mass communication and advertising, but it is not frequently found outside them: The media is(or are) not antibusiness.
