Answer :
Final answer:
Investigative reporting evolved from the 1960s adversarial approach triggered by events like the Vietnam War and Watergate, to today's challenges of 'attack journalism' and the scarcity of journalists, impacting the depth and regularity of such reporting.
Explanation:
The timeline of events in the development of investigative reporting is a testament to the evolving nature of journalism and its role in society. The 1960s marked a shift from a favorable perception of the president and passive coverage to a more adversarial approach and the birth of investigative journalism.
This shift was influenced by critical events, such as the Vietnam War and the Watergate scandal, highlighting the media's impact during the 1960s and 1970s. The earlier Progressive Era saw the rise of muckraking with exposés like Upton Sinclair's 'The Jungle' and the implementation of consumer protection laws. Despite the prestige investigative reporting has gained since Watergate, challenges such as the rise of 'attack journalism' and the scarcity of journalists in a 24-hour news cycle have caused concerns about the quality and frequency of investigative work.
