Concision refers generally to brevity, or the practice of using no more words than necessary to describe an idea. In the context of media criticism, the word concision is also used to describe the practice of limiting debate and discussion of important topics on broadcast news on the basis of broadcast time allotment.
Media critics such as Noam Chomsky contend that this practice, especially on commercial broadcasts with advertising,
encourages broadcasters to exclude people and ideas that they judge
cannot conform to the time limits of a particular program. This leads to
a limited number of "the usual suspects" who will say expected ideas
that will not require extensive explanation such as mainstream political
ones. Furthermore, introducing controversial or unexpected statements
that do not conform to those conventional ideas are discouraged as time
inefficient because the person will be required to explain and support
them in detail. Since this can often take considerable time in itself
and digress from the primary discussion topic of the broadcast, this is
discouraged. Alternatively, the explanation could be subject to
extensive editing for time which could lead to an inadequate
presentation of the subject's thoughts.
This media control idea is illustrated in the film documentary Manufacturing Consent: Noam Chomsky and the Media where journalist Jeff Greenfield
explains why a person like Chomsky may be excluded from being
interviewed on air because he takes too long to warm up. The film then
follows up with Chomsky himself explaining the concept while the film
gives examples of controversial statements he has made in the past that
would require extensive explanation in an interview.
The 1999 feature film The Insider has a dramatization of the media concept where journalist Mike Wallace goes public on a news show about the censoring of a controversial story on 60 Minutes.
When Wallace sees his interview broadcast, he is furious that his
testimony is limited to a cut part statement that does not adequately
explain his position and the only excuse from the producers he receives
is that it had to be cut for time.
