Final answer:
The yellow press was a form of sensationalist journalism that impacted public opinion and played a significant role in fostering support for U.S. expansion during the late 19th century, especially regarding the Spanish-American War.
Step-by-step explanation:
The term yellow press refers to sensationalistic and often exaggerated journalism that became prominent in the late 19th century, known for stirring public emotion and influencing public opinion. The most notable publishers associated with the yellow press were William Randolph Hearst and Joseph Pulitzer, who used bold and sensational headlines to sell more newspapers and influence the American populace. This was done to pay off the costs of expensive state-of-the-art printing presses by captivating the American people.
During the period leading up to and during the Spanish-American War, yellow journalism played a critical role in shaping public opinion and generating support for U.S. expansion. This form of journalism emphasized Spanish atrocities in Cuba and contributed to the public outcry that led to U.S. intervention, suggesting that the techniques of yellow journalism were akin to modern click-bait and fake news. Notably, though Pulitzer later established a prize for journalistic excellence, during this time, newspapers were not always trying to change public perspective as much as reinforcing existing opinions.
Yellow journalism fed into the narrative of Manifest Destiny in the 1890s, which was the belief that the expansion of the United States was both justified and inevitable. This period of journalism also raised questions about the challenges America faced in governing an empire, as it began to take on more territories.
