Journalism is a method of inquiry and literary style used in social and cultural representation. It serves the purpose of playing the role of a public service machinery in the dissemination and analysis of news and information. Journalistic integrity is based on the principles of truth, accuracy and factual knowledge. Journalistic mediums can vary diversely, from print publishing to electronic broadcasting, and from newspaper to television channels, as well as to the web, and to digital technology.In modern society, the news media is the chief purveyor of information and opinion about public affairs. Journalism, however, is not always confined to the news media or to news itself, as journalistic communication may find its way into broader forms of expression, including literature and cinema. In some nations, the news media is still controlled by government intervention, and is not fully an independent body.In a democratic society, however, access to free information plays a central role in creating a system of checks and balance, and in distributing power equally between governments, businesses, individuals, and other social entities. Access to verifiable information gathered by independent media sources, which adhere to journalistic standards, can also be of service to ordinary citizens, by empowering them with the tools they need in order to participate in the political process.The role and status of journalism, along with that of the mass media, has undergone profound changes over the last two decades with the advent of digital technology and publication of news on the Internet. This has created a shift in the consumption of print media channels, as people increasingly consume news through e-readers, smartphones, and other electronic devices, challenging news organizations to fully monetize their digital wing, as well as improvise on the context in which they publish news in print. Notably, in the American media landscape, newsrooms have reduced their staff and coverage as traditional media channels, such as television, grapple with declining audiences. For instance, between 2007 and 2012, CNN edited its story packages into nearly half of their original time length.This compactness in coverage has been linked to broad audience attrition, as a large majority of respondents in recent studies show changing preferences in news consumption. The digital era has also ushered in a new kind of journalism in which ordinary citizens play a greater role in the process of newsmaking, with the rise of citizen journalism being possible through the Internet. Using video camera equipped smartphones, active citizens are now enabled to record footage of news events and upload them onto channels like YouTube, which is often discovered and used by mainstream news media outlets. Meanwhile, easy access to news from a variety of online sources, like blogs and other social media, has resulted in readers being able to pick from a wider choice of official and unofficial sources, instead of only from the agenda-driven traditional media organizations.
