Journalism issue from "Agents of Power"

The issue of investigative journalism and its decline in most modern media outlets is a phenomenon which fascinates and intrigues me. How can it be that the one time primary source of information for writing news can have little or no place in contemporary media? It is a mark of how the world has changed and the increase in demand for daily news. Investigative journalism is when reporters deeply investigate a topic of interest, often involving crime, political corruption, or some other scandal. The investigation is in depth and consumes a large portion of time making it impossible to release investigative stories every day in newspaper and other media. The likelihood of defamation of those involved is also a deterrent for journalists and editors alike due to the possible legal implications. The nature of investigative journalism has become outdated and second to press release and readily available 'news.'
