Question

what is understanding media

Answer 1

The word media comes from the Latin plural of medium. The traditional view is that it should therefore be treated as a plural noun in all its senses in English and be used with a plural rather than a singular verb: the media have not followed the reports (rather than ‘has’). In practice, in the sense ‘television, radio, and the press collectively’, it behaves as a collective noun (like staff or clergy, for example), which means that it is now acceptable in standard English for it to take either a singular or a plural verb. 

Answer 2

This reissue of Understanding Media marks the thirtieth anniversary (1964-1994) of Marshall McLuhan's classic expose on the state of the then emerging phenomenon of mass media. Terms and phrases such as "the global village" and "the medium is the message" are now part of the lexicon, and McLuhan's theories continue to challenge our sensibilities and our assumptions about how and what we communicate
