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

the media is less interested in the party's policies

—James Lewis, Guardian Weekly

This use is not as well established as the mass-noun use of data and is likely to incur criticism especially in writing.
