In journalism and mass media, sensationalism is a type of editorial tactic. Events and topics in news stories are selected and worded to excite the greatest number of readers and viewers. This style of news reporting encourages biased or emotionally loaded impressions of events rather than neutrality, and may cause a manipulation to the truth of a story. Sensationalism may rely on reports about generally insignificant matters and portray them as a major influence on society, or biased presentations of newsworthy topics, in a trivial, or tabloid manner, contrary to general assumptions of professional journalistic standards.

Some tactics include being deliberately obtuse, appealing to emotions, being controversial, intentionally omitting facts and information, being loud and self-centered, and acting to obtain attention. Trivial information and events are sometimes misrepresented and exaggerated as important or significant, and often include stories about the actions of individuals and small groups of people, the content of which is often insignificant and irrelevant to the macro-level day-to-day events occurring globally.
