Final answer:
Newspapers that pushed sensational stories and fake news to sell more copies were known as yellow journalism, most notably practiced by William Randolph Hearst and Joseph Pulitzer in the 19th century.
Step-by-step explanation:
The term for newspapers that pushed sensational and often "fake news" to sell newspapers is yellow journalism. This style of journalism became popular in the late 19th century, particularly with newspaper moguls like William Randolph Hearst and Joseph Pulitzer, who competed fiercely to capture the public's attention and increase their circulation numbers. Yellow journalism involved using exaggerated and sensationalized stories, often with scant regard for the truth, and it was characterized by bold, scandalous headlines and the inclusion of pictures and comics to attract readers. The birth of yellow journalism coincided with technological advancements in printing and distribution, making newspapers more widely available and affordable, further fuelling this media phenomenon.
