Is media singular or plural?: Usage Guide
The singular media and its plural medias seem to have originated in the field of advertising over 70 years ago; they are still so used without stigma in that specialized field. In most other applications media is used as a plural of medium. The popularity of the word in references to the agencies of mass communication is leading to the formation of a mass noun, construed as a singular.
there's no basis for it. You know, the news media gets on to something
—Edwin Meese 3d
Edwin Meese 3d
