Final answer:
A series of investigative reports about political corruption in an online news source exemplifies the media's role as a Watchdog, which is essential for holding government accountable and maintaining transparency.
Step-by-step explanation:
A series of investigative reports about political corruption that appears in an online news source is an example of the media playing the role of a Watchdog. This role involves monitoring the actions of government officials and institutions to hold them accountable. It's an essential aspect of a democratic society, as it aims to expose wrongdoings and maintain transparency in public affairs. The Watergate investigations by Bob Woodward and Carl Bernstein are a classic demonstration of the media's watchdog function, as their reporting on the scandal led to significant political changes. Moreover, the media's ability to focus public attention on issues of corruption and report on such instances fulfills its duty to inform the public and provide a check on government power.
