News organizations are often expected to aim for objectivity; reporters claim to try to cover all sides of an issue without bias, as compared to commentators or analysts, who provide opinion or personal point-of-view. However, several governments impose certain constraints or police news organizations for bias. In the United Kingdom, for example, limits are set by the government agency Ofcom, the Office of Communications.
Both newspapers and broadcast news programs in the United States are generally expected to remain neutral and avoid bias except for clearly indicated editorial articles or segments. Many single-party governments have operated state-run news organizations, which may present the government's views.
