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.[1] 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.[2][3]
