Final answer:
Adolph Ochs purchased the New York Times to reinstate the ideals of informational and impartial journalism, contrasting with the sensationalism of yellow journalism and setting a new standard for objective reporting.
Step-by-step explanation:
When Adolph Ochs bought the New York Times, he brought back the ideal of an informational and impartial press. Ochs’ vision for the New York Times was to foster a dignified newspaper that emphasized important news on the economy, politics, and global affairs over gossip and comics, thus introducing a new standard for objective journalism. This contrasted with the sensationalism of yellow journalism, which was prominent before the advent of objective reporting. During the Progressive Era, newspapers began muckraking, leading to investigative journalism that exposed corruption in business and government. While the digital age poses challenges for investigative journalism, such as the scarcity of journalists and the fast-paced, profit-driven news cycle, the pursuit of transparency and the impact of exposés maintain their significance.
