Public opinion has often been influenced by newspaper? salespeople, vendors, editors

The correct answer is editors.

Public opinion has been a dominant concept in political communication. It refers to the preference or tendency of the general public, the society, towards specific social and political facts. Historically, public opinion has not been considered an independent factor, on the contrary, in general, it was a mere reflection of the media and the contents and opinions expressed in traditional mass media, like newspaper, TV, and radio. These contents are generated and influenced by editors' interests.
