Sensationalism

'The term is commonly used in reference to the media. Critics of media bias of all political stripes often charge the media with engaging in sensationalism in their reporting and conduct. That is, the notion that media outlets often choose to report heavily on stories with shock value or attention-grabbing names or events, rather than reporting on more pressing issues to the general public.
In the extreme case, the media would report the news if it makes a good story, without much regard for the factual accuracy.'
