Final answer:
It is true that the media, serving as a common carrier, alerts the public about important issues and events and acts as a linkage institution between the people and their government.
Step-by-step explanation:
When the media serves as a common carrier, it indeed alerts the public about important issues and events. This is a true statement because the media operates as a linkage institution, establishing a vital line of communication between the government and the public. This relationship allows the populace to learn about governmental actions and intentions, while also providing a means for government officials to understand public opinion.
The media plays numerous roles, such as ensuring the electorate is informed about national issues and elections through network news, and socializing citizens with the information necessary for a functioning democracy. Furthermore, the media acts as an agenda setter by deciding which issues should be at the forefront of public attention. With its responsibility to promote the public good, the media acts as a platform for debate and citizen enlightenment.
Technological advancements have expanded the reach and nature of media, with the advent of the internet and social media allowing for rapid dissemination of information which results in both positive and negative consequences for the public dialogue. Despite this, the news media is sometimes referred to as the "fifth branch of government" because of its significant influence on political processes and its ability to shape public perception and salience.
