Final answer:
Yellow Journalism used by newspapers like the New York Journal and the New York World played a role in fueling American support for Cuban rebels by sensationalizing Spain's actions in Cuba and swaying public opinion towards favoring intervention.
Step-by-step explanation:
Yellow Journalism significantly affected the rebellion in Cuba and shaped American views toward Spain. Major newspapers, including William Randolph Hearst's New York Journal and Joseph Pulitzer's New York World, used sensationalist reporting to depict the violence and suffering in Cuba, which fueled a sense of humanitarian concern among the American public.
This reporting style included bold, inflammatory headlines and exaggerated stories, often with a lack of factual accuracy, which evoked strong emotional responses from readers and incited public opinion toward supporting the Cuban cause for independence.
The intense coverage and sensationalism contributed to a growing sentiment that emphasized Cuban liberation, mirrored America's own struggle for independence, and vilified Spain's brutal methods.
It played a role in triggering the Spanish-American War and aligned with broader American interests such as the Monroe Doctrine, business investments in Cuban agriculture, and the safeguarding of regional stability. Ultimately, sensationalist journalism incited public opinion toward war and influenced support for Cuban rebels against Spain.
