Final answer:
Murray Edelman believed that networks did not provide a comprehensive range of perspectives on policy issues and lacked depth in government and public affairs coverage. He criticized the media for focusing on profits over in-depth reporting, which can influence the public discourse and credibility of news sources.
Step-by-step explanation:
Murray Edelman, the editorial director of VNS, believed that the networks did not take into account the wide range of views on policy issues and the in-depth coverage of government and public affairs. This criticism reflects concerns over media industry practices of prioritizing profits and focusing on the bottom line rather than providing comprehensive news coverage. The media's role, heavily influenced by technology, changed from localized control to a more national perspective, which can impact the information citizens receive and the credibility of news sources. Such changes affect the media's role as a gatekeeper in dictating public policy topics and may contribute to the polarization of political opinions and policies.
