The correct answer is stories about distant places were popular and encouraged calls for a larger American role in world affairs.
This is especially true when it comes to America's involvement in Cuba. The United States wanted to help Cuba to become free from Spanish rule. After the USS Maine (a US naval ship) mysteriously blew up, many newspaper reporters blamed Spain for the attacking. This resulted in Americans wanting war against Spain in Cuba. Ultimately, the US would win what is now known as the Spanish-American War resulting in an increased presence in international affairs. This war would result in the US gaining Cuba, Puerto Rico, Guam, and the Philippines. Many newspaper reportes would continue to cover these territories and how the US should be involved in their development to ensure liberties were guaranteed to these people.
