Sensationalism

Sensationalism is a manner of being extremely controversial, loud,
attention-grabbing, or otherwise sensationalistic.

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 to say they charge
that the media often chooses to report on shocking or attention-grabbing
stories, rather than relevant or important ones.
