===Publishing===
In U.S. publishing, five publishers known as the [[Big Five (publishers)|Big Five]] account for about two thirds of books published.<ref>{{cite news|last1=Kachka|first1=Boris|title=Book Publishing's Big Gamble|url=https://www.nytimes.com/2013/07/10/opinion/book-publishings-big-gamble.html|access-date=9 January 2017|work=The New York Times|date=2013-07-09}}</ref> Each of the companies runs a series of specialized [[imprint (trade name)|imprints]], which cater to different market segments and often carry the name of formerly independent publishers. Imprints create the illusion that there are many publishers, but imprints within each publisher co-ordinate to avoid competing with one another when they seek to acquire new books from authors.{{Citation needed|reason=Since that amounts to an accusation of wrongdoing, a source is pretty much mandatory.|date=January 2017}}

Thus, authors have fewer truly-independent outlets for their work. That depresses advances paid to authors and creates pressure for authors to cater to the tastes of the publishers in order to ensure publication, reducing viewpoint diversity. {{Citation needed|reason=According to whom/what source has viewpoint diversity been reduced? This seems to be written from the point of view of a frustrated author.|date=March 2017}}
